Meteorological Obfervations. 611 
Before the publication of the Boranrc Garpen, 
the world was not in poffeffion of any rational 
theory of the winds; that of .Dr. Halley, 
and others which have fucteeded it, not be-

principles, which (as I believe he was totally 
unacquainted with Dr. Darwin’s at the time 
he wrote) is a circumftance certainly not un- 
favourable to the theory. As many of the 
phenomena of meteorology admit of .an’.eafy 
and fatisfactory explanation by Dr. Darwin's 
theory, and as fome ;circumftances relative to 
the winds at Liverpool, cannot be well under- 
ftood without it, I ,fhall tranfcribe a fhort out- 
line of it, which, the ingenious author give: 
by way of recapitulation. 
‘* Norta - East Winp’ confifts of air pein

-occafionally produced; has an apparent direc-

acquired, in its journey, the increafing velocity 
of the earth’s furface. .Thefe winds are analo-

.and frequently continue in the. vernal months 
for four and fix weeks together, with a high 
barometer, and fair or frofty weather. 2, They
