 rally much more violent on the second occasion than on the first* 

 as if Putlam were placed first in the center of a circle described 

 by the storm and afterwards in the circumference of the same 

 circle, the whole series occupying from four to ten hours. 



With reference to temperature the registers are so unsatis- 

 factory that I deem it unnecessary to give any thing more than 

 the general result, namely that the highest temperature men- 

 tioned in them (at noon) is 89° in April, the lowest 78° in

 ever only from 73* to 86°. 



From observations made by myself during the last four months, 

 i find the average temperatures at the times mentioned below 

 to be as follows..

 is certainly greater than I should have expected, the low tem- 

 peratures have been observed on bleak rainy days when squalls 

 from the north-east were prevalent. From these data and cal- 

 culating by a well known formula which appears to be true, or nearly 

 truej for all localities* it results that the general mean temperature
