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.

171. In taking the weights, the powder is to be scooped up from the
filling-chest with the measure until it is heaped, tapped twice
moderately on the sides with the palms of the hands, and then struck
with a wooden straight-edge. If the weight differs materially from
that marked on the measure, a small compensating measure should be
used t
