APPENDIX OBSERVATIONS ON THE PORTS AND HARBOURS FROxM TRIPOLY TO DERNA, IN THEIR ACTUAL CONDITION.

In addition to what we have already observed with respect to the shores of the Syrtis and Cyrenaica, we have thought it necessary to subjoin the following short description of them, and of the supplies that ships may expect to meet with at the different places situated along the coast from Tripoli to Derna. The several places therein alluded to, will be found in the accompanying chart, which has been constructed from a succession of angles, carried on along the coast, assisted by astronomical observations, and chronometrical measurements, between three distant points, whose positions were well determined by Captain W. H. Smyth, R.N.

The instruments with which we were furnished, in consequence of the difficulty of carriage, were small, and their number limited ; they consisted of a five-inch theodolite, one four-inch and two eightinch sextants, a telescope for observing the eclipses of the satellites of Jupiter, a Rater’s azimuth compass, two pocket chronometers.

Nos. 2164 and 2184 of Mr. Arnold’s make*, and a measuring chain and tapes, &c.

Before entering into any particular description, we shall premise by stating that, between Tripoli and Bomba, there is not a harbour * In justice to Mr. Arnold, we must say that these two watches gave results beyond our mostsaiiguine expectations.
