Page 11 - These experiments were undertaken with a view to determine the resistance of the air to some forms of heads of elongated shot which were likely to be of practical use. The chronograph used was the one described in the...
Page 26 - A mathematical treatise on the motion of projectiles, founded chiefly on the results of experiments made with the author's chronograph.
Page 8 - The experiments referred to in this report have regard chiefly to initial velocity alone ; and for the small distance concerned, the law of resistance adopted may be thought of small practical importance, especially as before the experiments now...
Page 20 - The differential character of this instrument makes the results obtained from it worthy of a high degree of credit, " since in this way each experiment supplies means of testing the accuracy of the results, which are wholly wanting when only two intervals of time are measured, and that by two different instruments...
Page 23 - ... appears to have been in use for some years before that time in the School of Artillery of Metz, but Professor Bashforth without being aware of this, independently deduced the same law from his own experiments, so far at least as the law can be considered true, viz., for a limited range of the velocity.
