Meteorological Observations: 63 
under the authority of the vice-chancellor, giving precise di- 
rections for the use of the instruments, and for making me- 
teorological observations with correctness. These directions 
have evidently been digested with great care, arid after ma- 
ture consideration, and should they be generally adopted, 
they can hardly fail of producing the desired result. . The 
ideas*are, in general, similar to those of Professor Dewey, 
as stated in- the | preceding paper ; the As scree are too exten- 
sive to admit of insertion here ; as, however, the method pro- 
posed for obtaining the mean state of the winds, and the 
mean temperature, is peculiar, we will copy that yen from 
the printed tions. 
‘“* Count the number of times that each point of the com-

Do ee same with the entries of fair and cloudy, under the 
f Weather, counting the entries of snow and rain 
among a cloudy. 'To these subjoin the number of days on 
which it has rained or snowed, counted in the same manner, - 
and the quantity shown by the gauge ; also the warmest and 
_ coldest days shown by the mean, the highest and lowest de- 
gree of the thermometer, and the prevailing wind of the 
nth. 
Observations by the thermometer must be made every morn- 
ing, when it shows the lowest degree, every afternoon when 
it shows ighest degree, and every evening an hour after
