SHORT NOTES ON PROFESSIONAL SUBJECTS. 
No. 2. 7" M.L. polygonal rifled gnn, 7 tons, firing flat-ended hollow shot of 
compressed steel, 133£lbs. weight, 20 lbs. charge. 
No. 3. 7" M. L. “ Woolwich ” rifled gun 6^ tons, firing Palliser shot ogival 
headed, 114 lbs. weight, 22 lbs. charge. 
The projectiles were fired at a 6" wrought-iron plate backed by 42" timber, at 
a range of 10' yards. 
Besult :—No. 1 gun. Striking velocity 1410'; foot tons per inch of shot’s 
circumference 83. Punched a piece out of plate and drove it into backing, depth 
of indent 8J", shot broke up. 
No. 2. Striking velocity 1280'; foot tons per inch of shot’s circumference 71. 
Indent and bulged it behind, shot broke up. 
No. 3. Striking velocity 1432', foot tons 75, penetrated through all. Base of 
shot broke up, during penetration, head with point uninjured, weighing 22-| lbs., 
brought up by bulk head of ship. 
The difference of results given by No. 1 and 3 is very remarkable, considering the 
much greater striking power of the former, viz. 83 against 75 foot tons, the supe¬ 
riority of the latter must therefore be entirely due to material and form of shot. 
13. Expenditure of ammunition by the Prussian army during the 
campaign of 1866. The following information on this subject is extracted from 
Lieut.-Colonel Beilly’s memorandum on the Prussian army in relation to the 
Campaign of 1866. 
Infantry.* The greatest number of rounds fired during the war in the Second 
Army was 43 rounds per man. In the Eirst Army, the three battalions of the 
71st regiment at the battle of Koniggratz, expended about 72 rounds per man; 
but other regiments named only expended about 12 rounds per man, in the same 
action. The expenditure of infantry ammunition was, thus, very small. The 
actual expenditure of the Eirst Army, Second Army, and Armies of the Elbe and 
Main, and of the detached corps in Silesia, of about 400,000 men was 1,854,000 .
