The force of powder is owing to an elaftic fluid generated at the explofion, the fuddennefs of which depends upon the proportion of the ingredients, the contact between the nitrous and combuttible particles, and the fize of the grains, &c.

Page 28 - This is a consequence that may be deduced from a variety of experiments, and is perfectly agreeable to the principles of mechanics ; since the recoil and the range ought to be in the reciprocal ratio of the gun and the shot, making allowance for the resistance which these bodies meet with. Page 23 - If daily observations on powder put into damp magazines, and carefully preserved in barrels, are not sufficient to establish this fact, the following experiment will render it incontestable : — Let a quantity of well-dried powder be nicely weighed, and put into a close room, where the air is temperate, and seemingly dry, and be left for three or four hours ; on weighing it again, its weight will be increased.

The materials are put into a wooden trough, where they are ground together, to render the contact of the nitrous and combustible particles intimate and equal throughout the whole mass. The mixture...
