Стр. 5 - when a body cools in vacua, surrounded by a medium whose temperature is constant, the velocity of cooling for excess of temperature in arithmetical progression increases as the terms of a geometrical progression, diminished by a constant quantity.
Стр. 37 - OQ, and the second vertical, with its circumference resting on the flat surface of the first at P, so as to be driven round by the motion of the first disc. The velocity of the second disc will depend on OP, the distance of the point of contact from the centre of the first disc; so that if OP be made always equal to the generating line, the condition* of the instrument will be fulfilled.
Стр. 4 - The well known uniformity in the principal physical properties of all the gases, and particularly the perfect identity in the laws of their dilatation, render it very probable, that in this class of bodies the disturbing causes, to which...

The marginal edge of the incisive condition of the tooth and the median ridge of the molar stage are more...
