Not illustrated. 1875 Excerpt: ... tension of fired gunpowder when filling completely the space in which it was exploded, but also to determine the law according to which the tension varied with the density, it has been our endeavour to render both varied and complete the experiments instituted to ascertain these important points. In the first experiments described in this paper, as well as in the earlier series which formed the basis of Captain Noble's lecture delivered to the Royal Institution, the method adopted to determine the variation of pressure was as follows: --The space in which the powder was to be fired having been carefully established, the weight of the powder to be experimented with which would accurately fill the space was ascertained, and Yiq, -q, -fa, &c. of the vessel was successively filled with powder, which was then fired, and the resulting pressures determined. Later on it was found that, as with each description of powder the gravimetric density varied, it was more convenient to refer the pressure not, as at first, to a density arrived at by taking the weight of powder which completely filled a given space as unity, but to the specific gravity of water as unity. The densities given hereafter must therefore be taken to represent the mean density of the powder inclusive of the interstitial spaces between the grains, or, what is the same thing, the mean density of the products of explosion referred to water as unity. The gravimetric density of the modern pebble powders closely approximates to 1; that of the old class of cannon-powders, such as L. G., R. L. G., &c., varied generally betweenf-870 and-920; that of F. G. and sporting-powders was still lower. This statement applies only to the powder taken in considerable bulk. In our explosion-vessels, the gravimetric
