ture of Trebizond, the average daily variation for the year, as 
thus obtained being 5°, while that of Beirit the one which ap- 
proximates most, is about 65°. The great moisture of the at- 
mosphere is dbiserved in the tendency of every thing to rust, 
mould, or acquire dampness, even in the most favorable situation; 
_ Where not exposed to the direct rays of the sun. The amount-of 
rain which falls at Trebizond, and the great proportion of cloudy 
weather are also striking features compared with other parts of 
Turkey, and the remarks made in the preceding paragraph will 
furnish obvious reasons for these peculiarities. Its situation on 
the shore of the Black sea, hemmed in behind by mountains, 
and having a prevalent wind from the water, either in the form 
of a sea breeze or otherwise, are the causes referred to. Only 
eighty-three out of two hundred and sixty-eight records made 
in June, July, August, and September, 1843, and only one 
hundred and seventy-two out of three hundred and thirty inser- 
tions in the register for the.same months of 1844, were clear, 
and these months, it is to be remembered, include that part of the 
year when a clear, sky and dry atmosphere: — at all the 
other of our posts of observation. It has been remarked by one of 
the observers at Trebizond that the ordinary rules for predicting 
changes of weather from the state of the barometer, do not seem 
to hold true at Trebizond, but we unfortunately have no such 
records as will enable us to present the facts now alluded to. 
Doubtless the vicinity of mountains and the peculiarity of the 
‘winds must be the ground of the exceptions referred to; as they 
are found likewise to effect equally strange and sudden changes in 
temperature : e.g. March 10th, 1844, we have the thermometer 
71° at sunrise and 58° at 2p. m.; and Feb. 16th of the same 
year, 48° at sunrise, 37° at 2 p.m, and 45° at 9r.m. It may 
be well also to remark that Trebizond is less affected DY the
