Page 178 - Movements that may be executed toward either flank are explained as toward but one flank, it being necessary to substitute the word ' 'left " for ' 'right " and the reverse, to have the explanation of the corresponding movement toward the other flank. The commands are given for the execution of the movements toward either flank. The substitute word of the command is placed within parentheses.
Page 36 - The forts at Alexandria were badly bruised, but the more modern parapets were not seriously harmed. In the generality of cases the real damage they sustained could have been easily repaired in a single night. If the bombardment was directed against the forts in this, their defensive capacity, it must be pronounced a failure. If its object was the dismounting of the new rifled guns, it must be conceded that such results as attended the work of the inshore squadron (only one gun of this type being...
Page 124 - Measurements of the rate of explosion can be employed for determining the course of some chemical changes. In the explosion of a volatile carbon compound with oxygen, the gaseous carbon appears to burn first to carbonic oxide, and afterwards, if oxygen is present in excess, the carbonic oxide first formed burns to carbonic acid. . 6. The theory proposed by Berthelot — that in the explosion wave the flame travels at the mean velocity of the products of combustion— although in agreement with the...
Page 124 - ... that in the explosion wave the flame travels at the mean velocity of the products of combustion— although in agreement with the rates observed in a certain number of cases, does not account for the velocities found in other gaseous mixtures. 7. It seems probable that in the explosion wave — (1) The gases are heated at constant volume, and not at constant pressure ; (2) Each layer of gas is raised in temperature before being burnt ; (3) The wave is propagated not only by the movements of the...
Page 7 - Nothing can convince tyrants of their folly, but gunpowder and steel ; so put your trust in God, my boys, and keep your powder dry.
Page 124 - ... interaction of the steam. 4. Inert gases are found to retard the explosion wave according to their volume and density. Within wide limits an excess of one of the combustible gases has the same retarding effect as an inert gas (of the same volume and density), which can take no part in the reaction. 5. Measurements of the rate of explosion can be employed for determining the course of some chemical changes. In the explosion of a volatile carbon compound with oxygen, the gaseous carbon appears...
Page 152 - ... soft parts w 11 not only be limited to the track, of the bullet, but the utter destruction is noticed some distance into the tissues. The wound of exit appears like a bursting forth of the skin ; the track leading to the bone is conical in shape, the base of the cone corresponding to the wound of exit in the skin and the apex to the seat of fracture.
Page 124 - The propagation of the explosion wave in gases must be accompanied by a very high pressure lasting for a very short time. The experiments of MM. Mallard and Le Chatelier, as well as the author's, show the presence of these fugitive pressures. It is possible that data for calculating the pressures produced may be derived from a knowledge of the densities of the unburnt gases and of their rates of explosion.
Page 246 - In the event of the Prize being awarded to the winner of a previous year, a gold clasp, suitably engraved, will be given in lieu of a gold medal.
Page 1 - The dynamite gun is a new instrument of warfare, which has its own peculiar function in time of war. It cannot replace any existing weapon, nor can its place be wholly taken by any other. "2. The value of compressed air as a means of throwing projectiles from a gun is chiefly due to the ability of the gunner to exactly reproduce a shot, or to accurately increase or decrease the range at will, and to the accuracy of fire with low velocities. "3. The machinery employed by the Company...
