REGISTER OF THE WEATHER AT CORFU. 91 
Adie's sympiesometer I found most useful, and, I may 
mention, that I always found it correspond with a mercu- 
barometer kept in the garrison-library, although the sympie* 
someter always stood about an inch higher than the mer- 
cury, consequently 30.00 must be understood to represent 
29.00 by the register. Leslie's hygrometer has explained 
some of the phenomena attending the Sirrocco wind, which 
is the SW. and SE., but more particularly the SW. winds. 
You will observe by the register the extreme moisture of 
all the south winds, and the no less remarkable dryness of 
the north winds. 
The extreme moisture of the south y/inds, and the very 
frequent appearance of sheet-lightning during their ccmti^ 
nuance, seems to indicate their being highly electrical ; and 
the fact, that meat will not cure, wine keep if bottled, or 
paint dry, during a Sirrocco, I think favours the supposi- 
tion (not to speak of its very unpleasant effects on all living 
beings, such as are invalids particularly), that its great 
moisture alone could not produce ail those effects. I re- 
gret having no means of making any experiments on its 
electrical properties, but hope on my return to do so. 
I am, &c.

F. S, — I may mention that, according to the best obser- 
vations, Corfu is in Lat. 39° 38' SO" N., and Long. 17"
