What an illustration does it furnish of those refined celestial measurements to which we have referred; but even the sun himself, who seems so near and essential to us, so much our daily neighbour and companion that we regard him with more familiar minds, furnishes a perfect retinue of wonders. The paper in this volume, entitled "The Sun," is full of what the author calls "statements so enormous in all their proportions, that I dare say, before I have done some of my hearers will almost think me mad; or intending to palm upon them a string of rhodomontades, like some of the mythical stories of the Hindoos." What an astonishing paragraph, for instance, is the following:

This paper, on The Sun, while it is perhaps most simply written, is also the most startling in the volume. The telescope has revealed wonderful things in this great friend and most essential force of our whole system, in whose being-we trust we may say, we live and move without irreverence

and have our being; and in a manner and to an extent of which very few units compared with the thousands of millions of our race, have ever had any conception. It is remarkable that experiment has been brought with such an infallible refinement to bear upon that immense and distant orb that, by the operation of its powers we have become aware of the very materials of which it is composed. The paper under notice is a simple, readable essay, such as might beBut how shall I attempt to convey to you guile a parlour fireside of its dulness. Pro

fessor Tyndall more elaborately, in his essay on Heat considered as a mode of motion, evolved from the solar spectrum, by decomposing the light of the sun, the remarkable calculation that "the chances are more than 1,000,000,000,000,000,000, to 1, that is in the atmosphere of the sun."

Professor Kirchhoff has carried this splendid generalization forward to the discovery of calcium, magnesium, sodium, chronium, and other metals in the solar atmosphere; although others, and with us the rarer and more valuable, have as yet been undetected. The records of science are now full of these mysterious achievements and adventures of the human mind. Navigators discovering unknown shores strike upon our human sense of interest, but that solar spectrum, most beautiful and marvellous phenomenon, has led even, like a wonderful ship, to a strange coasting about upon the shores of that great continent of heat and light, seeming to bring its constitution and material a little nearer to us; and still, how almost less than nothing do we know. Most of our readers must be, at any rate, popularly acquainted with this interesting modern marvel of light; yet we think they will like to read Sir John Herschel's very popular description of it:

A ray of light is a world in miniature, and if I were to set down all that experiment has revealed to us of its nature and constitution, it would take more volumes than there are pages in the manuscript of this lecture.

When the sun's light is allowed to pass through a small hole in a dark place, the course of the ray or sunbeam may be traced through the air (by reason of the small fine dust that is always floating in it), as a straight line or thread of light of the same apparent size, or very nearly so, from the hole to the opposite wall. But if in the course of such a beam be held at any point the edge of a clear angular polished piece of glass called a prism the course of the beam from that place will be seen to be bent aside in a direction towards the thicker part of the glass and not only so bent or refracted, but spread out to a certain degree, so that the beam in its further progress grows continually broader, the light being dispersed into a flat fan-shaped plane: and if this be received on white paper, instead of a single white spot which the unbroken beam would have formed on it, appears a coloured streak; the colours being of exceeding vividness and brilliancy, and following one another in a certain fixed order -graduating from a pure crimson red at the end least remote from the original direction (or least deviated), through orange, yellow, green and blue, to a faint and rather rosy violet. This beautiful phenomenon the Prismatic Spectrum, as it is called - strikes every one who

sees it for the first time in a high degree of purity, with wonder and delight; as I once had the gratification of witnessing in the case of that eminent artist the late Sir David Wilkie, who, strange to say, had never seen a Spectrum till I had the pleasure of showing him one; and whose exclamations, though a man habitI shall not attempt to give any account of the ually of few words, I shall not easily forget. theory of this prismatic dispersion of the sunbeam; but an illustration of it may be found in a very familiar and primitive operation-the winnowing of wheat. Suppose I had a sieve full of mixed grains and other things-shot, for instance; wheat grains; sand; chaff; feathers; and that I flung them all out across shot would fall in one place, the wheat in ana side wind, and noticed where they fell. The other, the sand in another, the chaff in another, and the feathers anywhere nowhere; but none of them in the straight direction in which they were originally tossed. All would be deviated; and if you marked the places of each sort, you would find them all arranged in a certain order-that of their relative lightness in a line on the ground, oblique to the line of their projection. You would have separated to speak, on the ground; or a picture of what and assorted them, and formed a spectrum, 80 had taken place in the process; which would in effect have been the performance of a mechanical analysis of the contents of your basket.

Sir John touches, but does not discuss, the often-mooted question "whether the material universe be finite or infinite." Of still unanswerable. What we do know is, course any answer only leaves the question that light bears testimony to the uniform and all-pervading energy which sustains the universe; the evidence for gravitation fails us beyond the region of the double stars; or only leaves us with a moral conviction, amounting to a presumption, in its favour; but light bears testimony for unity of design and action throughout the wide system of the material universe. The lectures on "light" in this volume, form the most elab-, orate and lengthy papers: and here again we are brought face to face with marvels. One of these is the singular phenomenon or idiosyncrasy, as the author calls it, inherent in the molecules of material bodiesof "right and left-handedness;" also in colourless, transparent, and perfectly homogeneous fluid, which are found able to deviate the plane of polarisation of a ray passing perpendicularly through them.

Still stranger that it should do so constantly in one direction for the same fluid, but in opposite directions for different fluids; strangest of all, that even vapours should be found possessing the same property; such is the case.

Thus

oil of turpentine and its vapour turn the plane of polarization to the right hand, solution of sugar to the left, and so for a variety of other substances. This property has been made the basis of an elegant instrument called the saccharometer, by which the quantity of sugar contained in a given solution is ascertained by simple inspection of the tint so produced.

Such are among the wonders of which this little volume discourses-in that calm, reverent, and yet popular spirit, which can only produce upon the mind of the reader

a healthy wonder, rather than a vain curiosity. It is impossible to do more, in the space of a page or two, than merely to indicate its character, as really what it purports to be, a series of familiar papers, touching upon some of those great potential speculations; like the modern theories of heat, for instance, and its relation to the generation of every kind of force-speculations and discoveries which, as we said in the commencement of the paper, are like an entrance upon an infinite forest of thought, and creative essences and forms.

PARTON'S FAMOUS AMERICANS.*

The New York Times publishes the following card from Mr. Parton:

"The Times has been so indulgent in noticing my performances, that perhaps I ought to submit in silence to its censure, and I would do so if those censures related merely to the literary execution of my articles on Famous Americans. But when you accuse me of writing 'recklessly' you bring against me a moral charge of which I know I am not guilty. It is with me an invariable rule never to begin to write until I have exhausted every source of information accessible to me. If, in the use of the material thus accumulated, I commit errors, which of course I do, it is always from want of ability, never from want of care. Nor can I feel it to be true that I have no respect for anything human.' I trust that for every kind of human excellence, I have the respect that is due to it. I do not respect a reputation not founded upon merit, nor talent ignobly employed. Valor, self control, integrity, perseverance, consideration for others, I hold in the deepest respect,

recklessness with the assertion that he reads all the books that bear upon his subject, and then writes with what he considers care, but does not tell us what share the thinking faculty takes in his work, nor whether he uniformly aims at truth, never at effect. He answers the charge that he has "no respect for anything human" we should rather undertake to maintain that he has too much respect for things human by specifying certain qualities which he admires, and declaring that two of his great

It is true that he does not consider Clay absolutely faultless nor Webster altogether without merit; but the one is to be praised and the other to be condemned. Before he takes up his pen, if not, indeed, before he commences to read mind. Wishing the reader to be of his for an essay, the author has made his up opinion, he sets up on every page a guidepost, which points to the foregone conclu

sion.

In the opening sentence of the article close of the war removes the period precedupon Henry Clay, Mr. Parton says: "The ing it to a great distance from us, so that we can judge its public men as though we were the posterity to which they sometimes appealed." But it is certain that Mr. Parton is incapable of judging the great men of whom he writes, in this impartial spirit. are if written before the attack upon Fort His biographies would have been what they Sumter.

He has been saved thus far the quality of Mr. Webster's intellect dif- from the fate of many popular authors by ferent opinions obtained years ago, as they his industry, his skilful choice of subjects, still obtain. Mr. Parton gives a popular his activity of mind, his clearness of stateexpression to views long held in political ment, and by his common sense, when he circles, but he contributes nothing new. gives himself time to use it. The most striking portions of his article upon Webster, for example, those which have excited most controversy, were evidently inspired by Theodore Parker's well known sermon. What Mr. Parton has done is to translate Mr. Parker's language into his own vernacular and to find illustrations of his views in trivial incidents. His narrative is thus colored and the reader's mind is made up for him without his knowledge. It is not thus that a great man's character should be approached. The hidden sources. of his strength, the hidden springs of his conduct, the real inspiration of his language must be sought in a spirit of love and reverence. It does not do to cut the Gordian knot of such a man's complex motives. It must be patiently untied. A "speaking likeness" which says nothing to those who know the subject best is not a portrait that will live.

We might not have thought of making these suggestions had not Mr. Parton invited them. He ought to be content with a popular reputation, and not undertake to play the part of "posterity" for which he is in no respect qualified. As a popular writer he has great merits. Nobody goes to sleep over his articles. His commonplace is vitalized. His crude and frequently erroneous generalizations are soon forgotten in the bustle of the narrative. He just fails of being an excellent writer. He does not take the pains to condense or to prune, perhaps has not the discrimination necessary to judicious criticism of himself. He always writes just about so well, appearing to have no aspirations above a certain level. It would be difficult to find one felicitous expression in his last volume, or one graphic picture; yet there are numerous expressions that just fail of being felicitous, and sketches that just fail of being pictures:

"Oh, the little more and how much it is! And the little less and what worlds away."

The North American Review has been censured for admitting Mr. Parton's articles into the numbers which they enlivened, and undoubtedly our leading quarterly ought to be a model for its readers in point of taste as well as in point of temper and of scholarship; but it is, first of all, necessary that it should have readers, and these Mr. Parton attracted.

JOHN PENINTGON.

Mr. John Penington, of Philadelphia, who died on the 18th inst., was the last, if not the only, American bookseller who represented the old traditional booksellers. A scholar of fine parts, thorough in his knowledge of bookselling, with judgment and skill, a bibliographer in its broadest and best sense, he was an honor to the craft, and he took pride in it. He was a man of fine taste, of large reading, and of exhaustless service to all who were curious in scholarship or earnest in the study of letters. Descended from one of the old, respected, and wealthy Quaker families of Philadelphia, it was accident that made him a bookseller. His father's large fortune was suddenly lost. During his youth Mr. John Penington had gathered a valuable collection of books, and had frequently contributed to the literary proceedings of the various learned societies of his native town. Not caring for general mercantile pursuits, and suddenly thrown on his own resources, he quietly turned his library into his stock in trade, and with it opened one of the best bookstores of the country. Proud of his books, and contented with his shop and the fair profit which it brought him, he never allowed himself to be tempted from his chosen pursuit. His shop became the gathering place of scholars and men with a taste for letters, and one generation after another grew up almost under his

Bookselling with him was not so much a trade as an art; books with him were valuable for their real, substantial merit; the book-buyer was precious in his eyes who knew what he wanted and why he wanted it. He never got rid of his old love of books for their own sake, and that love was too well founded in a knowledge of books ever to be lost in a poor ambition to become a great booksellera mere trader in so many thousand volumes of which he knew nothing and thought less. One of the matters of his trade in which he took pride was the fact that his list of subscribers to the new edition of Brunet was the largest outside of Paris, and thus he brought together the oldest bibliographer of the Old World and the youngest student in the New. With Brunet and with Bossange, as with all the other leading booksellers in Europe, his relations were intimate, and ripened always into fast friendships, each man finding in the other much to like and to respect. The sound judgment which characterized him in his private business was not lost in other things; and in political and public matters his advice was always safe. He was frequently called upon to assist members of Congress in framing such parts of the successive tariffs as were within his special business knowledge, and his recommendations were never biassed by his own interests. The loss of such a man, capable in his business, proud of it, and making himself dear to his friends, is at all times a great one. Particularly is this the case now and here, when study and scholarship are taking their accustomed places, from which they had been seriously disturbed by five years of war. The trade of book-selling in his hands was elevated to the dignity that it really acquires in the hands of competent men. Such men are rare everywhere. Here, unfortunately, they are growing rarer every day. In growing great rapidly we are not always growing wise, and the men who mean to study and want a book-shop and a bookseller to furnish them with the tools they need, will look long and vainly for such help as they

M. THIERS has attacked the foreign policy of the Empire in a speech which will be read with breathless interest by most Frenchmen. Seldom has there been more vigorous or skilful invective delivered against the conduct of the French Foreign Office. The moment was not inopportune. Half France has been wondering whether it is possible that the newfangled policy of Imperialism is, after all, a series of suicidal blunders, and that NAPOLEON III. is an overrated man. M. THIERS has seized the critical occasion to pronounce with all the authority of a connoisseur that, considered as a diplomatist, the EMPEROR is a failure. The old tribune, which this year has reappeared by Imperial permission in the Chamber, seems to have been restored just in time. The veteran debater and ex-Minister spoke of the familiar rostrum as of an old and valued friend, and, standing where he had not stood for twenty years, seemed like the ghost of old French Governments inveighing against the spirit of the new. M. ROUHER, himself no mean orator, was scarcely equal to the task of coping with the complete and polished essay of his animated antagonist. The admiration of the Chamber was equitably divided between the two opposite harangues, but the vehement address of the Opposition leader has produced out of doors a deep impression which the assurances and protestations of the Minister have not yet removed.

The charge brought by M. THIERS against the policy of the Empire is that it is not the policy of common sense. It has only succeeded, he thinks, in leaving France stranded and isolated in the middle of the Continent. Her true interest, he conceives, is not to preside over the rise of nationalities or the agglomeration of nations, but to stand by the balance of European power. Reduced to plain terms, this means nothing more than that, when Europe is weak, the French Empire will be strong. The "balance of power" is only a courteous way of expressing the hopeless division of the Con
