Temperature may be conceived to depend upon the velocities of the vibrations; increase of capacity on the motion being performed in greater space; and the diminution of temperature, during the conversion of solids into fluids or...
Página 422 - It seems possible to account for all the phenomena of heat, if it be supposed that in solids the particles are in a constant state of vibratory motion, the particles of the hottest bodies moving with the greatest velocity, and through the greatest space; that in...

Página 206 - It is covered with a whitish bark, slightly bursting in longitudinal furrows. Near the ground this bark is, in old trees, more than half an inch thick, and, upon being wounded, yields plentifully the milky juice from which the celebrated poison is prepared.

His figure was drawn from a branch of that which was called the male tree, sent to him from the same place, and established the identity of the poison tree of Macassar and the other eastern islands with the antshar of Java. The account of this author is too extensive to be abridged in this place, it concentrates all that has till lately been published on this subject : but the relation is mixed with many...

But it requires much bruising, washing, and a long immersion in water before it can be used; and even when it appears completely purified, persons wearing this dress, on being exposed to the rain, are affected with an intolerable itching, which renders their flimsy Covering almost insupportable. It will appear from the account of the manner in which the poison is prepared, that the deleterious quality exists in the gum, a small portion of which still adhering to the bark,...
Página 204 - It is in fact more surprising that a subject of so much notoriety in the district of Blambangan, and of so great celebrity and misrepresentation in every other part of the world, should so long have remained unexplored, than that it should finally have been noticed and described; and since my visit to that province, I have more than once remarked the coincidence which led two persons, of nations different from each other, and from that which has been long in possession of the island, who commenced...

He became engaged with private pupils in "November following, and took the degree of BA (with superior credit, being second Wrangler,) in January 1759. He was elected fellow of Trinity college...

The stars shone with a lustre that far exceeded the brightness which they exhibit when seen from the usual level ; and had so little tremor in their light, as to leave no doubt on my mind that, if viewed from the summit of the mountain, they would have appeared as fixed points. How improved in those altitudes would be the aids which the telescope gives to vision ; indeed, the clearness of the air was such as led me to think that Jupiter's satellites might...
