The year 1861, with respect to its temperature, exhibited, as a 

 ^hole, nothing extraordinary, the mean of the year differing from the

 The monthly means, moreover, did not differ in a marked degree from 

 the means proper to the several months derived from twenty-two 

 years, the average deviation, without regard to sign, being 2°.24 ; 

 while the average deviation in the whole period of twenty-two years, 

 and referred to the same standard, was 2°.44. If, however, the signs 

 of the deviations be taken into account, it will be seen that the com- 

 pensations by which the annual mean was maintained, were of the 

 kind that may be styled unseasonable, being such as tended to weaken 

 rather than to intensify the distinctive characters of the different 

 parts of the year. Thus, from May to August — comprising the 

 greater part oi the year in which the temperature is above the yearly 

 mean — the monthly means were relatively low; while in February
