414 Capt. Noble. Note on the Energy absorbed [Feb. 4, 



The curve shown on p. 413 exhibits for the charges used and 

 explosives I have named the results of these experiments, and, 

 employing these values, the following tables give for uniform and 

 parabolic rifling the value of R, that is, the pressure tending to 

 give rotation calculated from formulae (1) and (2). They also give 

 the pressure acting on the base of the shot, and the velocity in the 

 bore. 



T) able III. Parabolic Rifling, Amide Powder.
