It is an old obfervation, that a N.E. wind in this coun- 
try generally makes the barometer rife. This naturally 
leads to an enquiry, whether there be any general con- 
nection of the rife and fall of the barometer with the fet- 
ting of the wind. Upon comparing the general account 
of the barometer for the year 1774, hated at the end 
of the meteorological journal, wdth the journal at large, 
I found, that in feven months out of the twelve the 
greateft height of the barometer was accompanied with 
a North-eaherly wdnd; and in eight months out of the 
twelve, the leaft height of the barometer was accompa- 
nied with a S.W. This incited me to take the trouble of 
making out the preceding table, w^hich fliews the mean 
height of the barometer which accompanied each wind in 
every month, and for the whole year. And it appears, that 
though the barometer may be almoft at any height w ith 
any wind, yet the mean height was greater, in the courfe 
of the laft year, with the winds which fet from that fe- 
micircleof thecompafs, which is intercepted between the 
points of W.S.W. incluhve and E.N.E. excluiive, going 
round by the W. and N. than with the winds w^hich fet 
from the oppofite femi-circle intercepted between E.N.E. 
incluhve and W.S.W. excluhve, going round by E. and S. 
In the former femi-circle the W. and N.E. give the great- 
eft mean height, and in the latter the S.S.E. and S.W., 
o;ive the leaft ''-b

* It is to be noted, that the means of the whole year, ftated in the lowernioft 
horizontal row, are not found by collefting the means of all the months Into 
one fum, and dividing by the number of months (for this method would always 
be fallacious, except each wind had blown for the fame number of days in all the 
different months); but by adding together the heights attending each wind day 
by day, and dividing the fum by the number of days each wind blew in the 
whole yeati 3
