447. oldal - Effects of Rarefaction, by partly removing the Pressure of the Atmosphere, upon Flame and Explosion*." The experiments of the latter show that rarefaction produces striking alterations in the size and character of the flame, but do not touch the...
57. oldal - From the series of observations made at and below London Bridge, compared with the river as far up as Kew and Oxford, Mr. Stevenson is of opinion that the waters of the Thames seldom change, but are probably carried up and down with the turn of the alternate tides for an indefinite period, which he is of opinion may be one, if not the principal, cause of what is termed the extreme softness of the waters of the Thames. Mr. Stevenson has made similar experiments on the Rivers Forth ,and Tay, and at...
449. oldal - It would appear, then, that the heat given out by the compression of gases is the real cause of the combustion which it produces, and that at certain elevations of temperature, whether in rarefied or compressed atmospheres, explosion or combustion occurs, ie bodies combine with the production of heat and light.
246. oldal - In seasons with little rain many of the seeds fail, and a great number of the young shoots die; so that it is frequently necessary to plant a piece of ground several times successively. A plantation of cinnamon, even on good ground, cannot be expected to make much return before eight or nine years have elapsed. The plantations from which a considerable part of the cinnamon is procured are Kaderang, Ekele, Marendahn (Colombo), and Morotta.

248. oldal - Chilaw perceives a shoot of proper growth, he strikes an instrument which resembles a small billhook obliquely into the shoot. He then gently opens the gash to discover whether the bark separates freely from the wood ; should this not be the case, he leaves the sucker for a future time. Some shoots never arrive at a fit state for decortication. Plants of several years...

227. oldal - Course of Lectures on the Theory and Practice of Midwifery, and on the Diseases of Women and Children, Oct.
450. oldal - The cooling power of mixtures of elastic fluids in preventing combustion must increase with their condensation, and diminish with their rarefaction ; at the same time, the quantity of matter entering into combustion in given spaces, is relatively increased and diminished. The experiments on flame in rarefied atmospherical air, show that the quantity of heat produced in combustion is very slowly diminished by rarefaction, the diminution of the cooling power of the azote being apparently in a higher...
