27. The Aide-Memoire portatif de Campagne of 1864, from which the 
preceding data are chiefly derived, contains full instructions on the use and 
employment of the guns referred to under all circumstances : characterized 
by that clearness, conciseness, and practical character which distinguishes 
the military manuals of the Trench; but it would be beside the purpose of 
this paper to quote largely from them. The work itself, notwithstanding its 
primary reference to a special material, may be cordially recommended as 
containing in a very small compass a great deal of matter of general interest 
to the artilleryman. 
* 36 boxes for 6 guns, which with 64 in reserve, carry 150 rounds per gun. 
f These weights differ a little from those at p. 346, which were taken from a different authority. 
ERRATUM. 
Table I. p. 344, for “1 turn of rifling in 8-858 feet,” read “ 1 turn of rifling in 88‘58 inches or 
7-38 feet.”
