288 Meteorological Register. 
is enclosed in 1 box, and suspends a weight upon a small cylinder, 
which, of course, increases in diameter at every degree marked upon 
the dial, which is upon the outer surface, the whole adjusting itself ey 
to the wind by a tail orrudder. The days marked fair agree almost 
exactly with those of 1834, ’3, being for the first of those years 
two hundred and thirty one, and the second two hundred and thirty 
two. The quantity of rain has been a fair average ; the heaviest 
being the 10th of October, 3.63. The greatest change I have no- 
ticed has been in the number of days marked “south winds”—of 
those sultry winds, we had in 1833 sixty five days, and in ’84 forty 
days, and the corresponding years thirty and thirty four north wind 
days against fifty of thisyear. ‘T’o this we must mainly 2, res - 
low range of the thermometer for the latter. The variable 
too have prevailed to a greater extent than usual. 
My other occupations have prevented my making any peste 
observations upon the electrical state of the atmosphere ; perhaps 
those days marked “ thunder” may give you some idea upon that 
subject. The land breeze, which generally springs up between eight 
and twelve o’clock at night, has prevailed to about the same extent 
as-usual. You will observe that the mean of three daily observa- 
tions gives the same result within a fraction, as the mean of two ex- 
tremes per register thermometer. I would therefore recommend 
the use of the latter in a climate like this, as being attended with far 
less trouble ; the only objection is that the quicksilver in the mercu- 
rial tube, is apt to become deranged when the instrument has been 
long used. 
At the time of the remarkable meteoric display in November, 
1833, I did myself the honor of making to you some observations 
upon the subject. I have not yet learned whether they reached 
you.* I remain, sir, with high respect, 
Wet Your very obd’nt serv’t, A. Matuvory.
