OBSERVATIONS ON THE PORTS AND HARBOURS PROM TRIPOLY
TO DERNA, IN THEIR ACTUAL CONDITION.
I n 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
th a t 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 b y astronomical observations, and chronometrical
measurements, between three distant points, whose positions were
well determined b y 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 eight-
inch sextants, a telescope for observing the eclipses of the satellites
of Jupiter, a Kater’s azimuth compass, two pocket chronometers,
Nos. 2164 and 2184 of Mr. Arnold’s m ak e* , 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
heyond our mostsanguine expectations.
