N.B.—There is a variation in the dimensions of the above boxes, as made, of 1/3 of an inch, on an average, in their exteriors.
168. Percussion-caps and bullets for small arms will be supplied from the Ordnance Yard at Washington.
169. The boxes in which cartridges for small arms, caps, primers, etc., are packed for distribution to vessels, are to be marked with the number they contain, and the kind of arm for which they are intended. At the expiration of the cruise they must be carefully returned into store, and the Gunner will be held peculiarly responsible for their loss.
170. Standard powder-measures for filling cartridges for great guns will be made at the Ordnance Yard, Washington, and distributed as they may be required for the use of vessels and shore magazines. As the gravimetric density of powder varies from 860 to 940, the weight of the contents of ten measures should be ascertained for each lot, and allowance made accordingly before filling the cartridges.
