ing by fo very flioit a duration of cold during the nights 
in thefe months, and by a well-timed and critical contri- 
vance of fecuring this momentary degree of cold, they 
have procured to themfelves a comfortable refrefliment 
as a recompence, to alleviate, in fome degree, the intenfe 
heats of the fummer feafon, which, in fome parts of In- 
dia, would be fcarce fupportable, but by the affiilance of 
this and many other inventions. - 
Accompanying I beg leave to offer you fome obferva- 
tions, I made in the year 1767 O’), in the province of Alla- 
habad, on the temperature of the weather, which will 
ferve to elucidate the extraordinary and fudden changes 
incident to that part of Afia. Alfo fome remarks on th© 
weather during my voyage to England, particularly fpe- 
cifying the fituation we were in when the obfervations 
were made.

Your moft obedient humble fervant,
