392 The Rev. S. Haugliton's Account of Experiments to 



made on the recoil of the two-groove rifle with the three bullets 

 already described. 



Table I.— Minie BiOlet. 



Mean velocity = 847 feet per second. 



Mean quantity of motion measured in avoirdupois pounds 

 moving through 1 foot per second = Si'SS lbs. 



Table II.— Sugarloaf Bullet. 



Mean velocity = 863-7 feet. 



Mean quantity of motion = 82"63 lbs. 



Table III.— Belted Bullet. 



Mean velocity =1021-68. 



Mean quantity of motion = 70'39 lbs. 



The Minie regulation-rifle barrel having been attached to the 

 pendulum, formula (1) was calculated with the following con- 

 stants, and the results are given in Table IV. 



The carbine barrel was then attached to the pendulum and 

 the recoil observed. The results arc contained in Table V.
