this is not to such a degree as may be imagined, 
as will appear from the following remarks : — On 
examining the Aphides issuing from the eggs, on 
the Apple trees, in the spring of the year 1823, none 
of the eggs appeared to have perished, although the 
frosts had been severe the preceding winter, about 
the middle of which we had it constant or nearly 
so for a period of five weeks ", there was also 
much snow and rain through the winter, and 
although the summer months in the same year 
proved uncommonly wet, this species, and others 
of the same genus, prevailed extensively in these 
parts of the country, and I believe pi’etty generally 
throughout the kingdom. Dry weather does not 
destroy or hinder the increase of these insects, but, 
on the contrai-y, proves more conducive to their 
increase than wet dull weather ; this was, it is true, 
not generally exemplified in the summer of 1826, 
for although it will be remembered, that it was 
remarkable for heat and drought, nevertheless those 
insects did not generally prevail to any serious 
degree. For example, the hops, which are often 
much annoyed by them, were pretty free from 
their attacks ; fruit trees and plants also generally 
escaped without much injury j but the Brassica 
tribe were much infested throughout the summer 
months. Why they prevail at one time more tlian 
another may be partly accounted for in this way. 
It will be allowed by all that the Almighty uses 
various means to put us in remembrance of his 
omnipotence, lus omniscience, his M'lath, and his
