Art. .^Determination of the Longitudes and Latitudes 
of thirty four places in the Mediterranean. By Mr Char- 
les Rumker. Communicated by the Author. 
_L HE longitudes of the places contained in the following 
Table, have been fixed by measuring, with the timekeeper, their 
meridional distance from La Valette on several short excur- 
sions which I made from that port, the longitude of which has 
been assumed at 14° 38."6, as determined by observations 
given in a preceding paper. (See p. 280.) 
In those places where the latitude is not given, I had no 
opportunity of observing it with the sextant, the visible horizon 
being obstructed by land, and the sun’s meridional altitude 
being too greatfor the artificial horizon. I then made use of the 
latitude taken from the chart in computing the hour-angle.
