A Chart of Ceuta and Tetuan Bays; in avhich are pointed out the most advantageous Places of Rendezvous for the Purposes of Victualling and Watering a Fleet. Surveyed, and particularly designed for the Use of the British Navy, by Captain John Knight, of the Royal Navy. 5s. Steel.

THIS chart is chiefly interesting, as it includes a considerable portion of the African shore. There is also inserted in the plate a plan of the Zaffarine Islands, which lie about fifty leagues E.S.E. from Gibraltar, and ten leagues S. E. by E. from Cape Treforcas. We shall extract a part of the observations.

Captain Knight having found the Spanish and other charts of this part of Africa to be extremely incorrect, and the advantages of Tetuan Bay to be little known, was induced, by these considerations, to survey it in 1799.

The bays of Ceuta and Tetuan afford good shelter for a fleet with a west by northerly or southerly wind. In both are some spots of foul ground, more particularly in Ceuta Bay, in ten to seventeen fathoms depth. Off the mouth of the river Maravi, near to the south part of Tetuan Bay, and off the white tower on the hill, is a most admirable watering-place for a fleet;-and here, on application and some slight compliments being made to the governor, fresh provisions of every kind may be obtained reasonably and in abundance, with wood for fuel. In June 1799, the British fleet under the orders of vice-admiral lord Keith anchored here, and was plentifully and expeditiously supplied with water from the river. Here ships may ride in perfect safety, on a sandy bottom, in eighteen to twenty-two fathoms, with the wind from N.W. to S.S.E. at two miles distant from the shore; but within that depth the ground is in some places rocky.

The mode of watering is by landing the casks, and rolling them over a sandy beach, about thirty yards wide, into the river. The native Moors and Arabs are civil.

In Ceuta Bay is also a good anchorage, and ships lie there better sheltered; but, on account of its vicinity to the garrison of Ceuta, it it less frequented in time of war. When the easterly or Levant winds spring up, it becomes necessary to get under way. The approach of these winds is generally indicated by a current from that quarter, and by a clear atmosphere for some hours before the passing clouds begin to cap the hills. In these bays, as on the opposite coast towards Gibraltar, the flood sets to the westward, and on the days of full and change the tide begins to set to the eastward at one o'clock.'

A Survey of Bear Haven and Bantry Harbour, in Bantry Bay, by John Knight, Esq. Rear Admiral of the Blue. 5s. Steel.

BANTRY Bay is sufficiently noted in modern history; but as we believe the French are disgusted with fruitless attempts on Ireland, there can be little apprehension of their using this chart in any future invasion. It does honour to admiral Knight's abilities in this department, and may be useful in correcting the maps in this interesting part of Ireland. Bear Haven lies beyond Great-Bear Island, and the entrance is grandly marked by Hungry Hill, which, according to this Survey, is 2160 feet above the level of the sea.

A Chart of the East Coast of England from Lowestoff to Cromer, en which are laid down Yarmouth Roads, from a Survey by John Knight, Esq. Rear-Admiral of the Blue; and Hasborough Gat, from a Survey by Captain Joseph Huddart; and published by Order of the Trinity House. 45. Steel.

THE public is greatly indebted to admiral Knight for this delineation of a shore proverbially dangerous. It is accompanied with several views of land, and some short observations by the intelligent author.

A Chart of the River Thames from London Bridge to Woolwich Warren; drawn from an accurate Trigonometrical Survey. 45. Steel.

USEFUL, and neatly engraved. It is accompanied with the rules concerning ballasting in the port of London; by a perpetual table of high water at London Bridge, and by some observations, amongst which is the following:

"Variation of the Compass.-In the year 1580 the variation of the magnetic needle, as observed in Limehouse by William Borough, was 11° 5' east: it has ever since been approaching westward, and is now 24° 30' west, having varied its position thirty-five degrees and a half in about 220 years. Its motion appears to have been unequal. In the last fifty years it has increased seven degrees.'

This chart includes an exact representation of the new docks and canal in the north of the Isle of Dogs.

A Survey of the Virgin Islands, by George King, Land-Surveyor to those Islands. 45. Steel.

OF this West-Indian groupe the two chief islands are Tortola and St. Thomas. There is reason to believe that this Survey, which is accompanied with views of land, is one of the most accurate which has yet appeared.

Chart of the White Sea from the North Cape to Archangel and Onega; deduced from the latest Surveys and Observations, by John Hamilton Moore. Two Sheets*. 7s. 6d. Sold by the

Author.

THIS large chart includes several small surveys:-1. The river Dwina to Archangel; 2. The entrance of the river Puszlachta; 3. The Bight at Cape Sweetnose. It appears to be delineated with considerable accuracy; but we should have expected that the names even of the smallest islands would have been inserted in a chart on so large a scale. There are several minute views of the North Cape; but the vacant and useless paper is so extensive as to leave room for many other views of land which might have been of great consequence to the ma

riner.

A New Chart of the British Channel, enlarged and improved by John Hamilton Moore. Three Sheets. 75. 6d. Sold by the Author. THIS extensive chart reaches to more than twelve degrees west of Greenwich; thus including the south of Ireland. The eastern boundary extends beyond three degrees to the longitude of Cadzand. There are small compartments off Falmouth, the Downs, Dartmouth, Plymouth, Cork Harbour, and Portsmouth, with the Isle of Wight; there are also several views of headlands, &c. Major Rennell informs us that there is no good chart of the British Channel; and the present is probably one of the best extant. It is executed in a coarse bold style.

A New Map of Great-Britain, particularly showing the Inland Navigation by the Canals and principal Rivers. Bowles and Carrington.

WE before mentioned a map of the same nature, published by Mr. Smith. The present map includes the whole course of the rivers; but the extent to which they are navigable is not in

dicated with that precision which might have been expected. The mark of an anchor at the mouth, and of another on the precise spot to which they are navigable, is adopted in the French maps of this nature; and it would be a still further improvement if there were merely a stroke across the river, and the number of tons added.

REVIEW OF MAPS;

CONTAINING

Extracts from the foreign Journals, concerning those which seemed interesting, but have not yet reached England, or, at least, have not fallen under our Observation*.

AT Vienna has appeared a new and corrected edition, in two large sheets, of Ecker's Northern and Southern Hemispheres, laid down stereographically for the horizon of Vienna. These maps were first published in 1794, and form a part of Schrable's General Atlas of Germany. From the account of them given in the Journal of Gaspari, it appears that they do not contain the discoveries of Vancouver or of La Pérouse. They seem to be in imitation of the two Planispheres, published at Berlin in 1783, by professor Bode; but the outline of the coasts is not delineated with equal exactness, and there are several errors of longitude and latitude. There is a volume of letter-press, which is itself far from being immaculate.

Sotzmann has published at Berlin a Map of the Northern Part of Upper Saxony, which contains the March of Brandenburg and the duchy of Pomerania, with the post-roads, &c.; being a kind of reduction of his provincial maps. But these maps are not trigonometrical; and it is surprising that the Germans, who pretend to such geographical hypercriticism, should not give the example of tolerable maps of their own country. Yet the barbarous division into antiquated circles, and the distinct interests of the petty sovereignties, must prove obstacles to such a design. There seerns also to remain a radical want of

It is almost unnecessary to mention, that, in this part of our Review, we must chiefly abide by the opinion of the foreign journalists.

taste in the Germans, who are more inclined to plod in the quarries of literature, than to build palaces. The very use of the old black letter in their publications is a sufficient proof of barbarism; and even the maps published under the eye of the journalists, from observations at the observatory near Gotha, -ironically, by some of our map-sellers, called Mr. Seeberg's works, from the German Sternwarte Seeberg, i. e. an observatory,may indeed be accurate, but are such poor productions, and so destitute of taste and information, that no collector of maps would wish to possess one of them.

Baron Hermelin's Atlas of Sweden is nearly completed; the first division containing the northern provinces, the second di vision Finland, and the third Sweden Proper. It is accompanied with views of various parts of the country:

.

1. The fall of the Hadtjajock on the lake Saggal, in Lulea Lappmark;

2. View of the range of mountains at Quickjock, in Lulea Lappmark;

3. Gilliware, from the southern bank of the Wassera Elf, in Lulea Lappmark;

4. View of the mountain Wigeln over the lake Oresund, from Beckaas in Norway;

5. View of the mountain Ruten from the north-east end of the lake Malmagen;

6. View of the range of mountains between Herjeadalen and Norway, taken from Mount Funnesdal;

7. View of the forges and smelting-houses at Ljusnedal, in Herjeadalen ;

8. View from Wermasvuori towards the lakes Jockijavoi and Umolanselka.

9. View of Stockholm.

The latter sheets are superior in neatness and accuracy to the first; but the journalists of Weimar exclaim as usual against the neglect of astronomical observations. We must remind them that the study of geography is very widely diffused; while not one in a thousand pays any attention to the astronomical part, after having learned the elements of geography. In reading books of history or travels, &c. maps are consulted with a view to the relative situations of places, and a general conventional accuracy is all that is expected. Few readers are so ignorant as not to know that a map or plain surface cannot represent any part of a sphere with complete mathematical precision; nor must it be forgotten that astronomical observations depend on the skill of the observers, and that many are found to be erroneous.

We agree however with the foreign journalists concerning
