3. One prismatic compass, three and a-half inch, with silver ring:
5 pounds 5 shillings.
4. One six-inch semicircular protractor, with Vernier: 3 pounds 3
shillings.
5. One glass plane artificial horizon, ordnance pattern: 4 pounds 4
shillings.
6. One brass rolling parallel ruler, two feet long; must not weigh
less than five pounds.
7. One twelve-inch brass sector: 1 pound.
8. One set of six-inch ivory plotting-scales, with offset scales
complete: 4 pounds.
9. Two steel straight-edges, three feet each.
10. Four sixty feet land chains.
11. One small compact case of good sector-jointed, drawing
instruments with ivory parallel ruler: 3 pounds 3 shillings.
12. One very small achromatic telescope of the strongest make, not
to exceed six inches in length, when closed: 1 pound.
13. A small chemical blowpipe with ivory mouthpiece, and two
platina tips; also some platina foil and wire.
14. Two Nautical Almanacs, 1858 and 1859.
Leather cases and straps for theodolite, circle, and prismatic
compass. A catalogue of instruments with prices.
N.B. I should wish the theodolite and circles to be packed very
differently from the usual way, as many instruments are seriously
injured by the box warping either inwards or outwards; in the one
case pressing too much on the instruments, and in the other, which
is worse, leaving them too much space, so that they shake about
whenever the box is carried.
