REMARKS ON THE FOREGOING TABLES. 



The distinguishing feature in the climate of this section of the State, is the uniformity 

 of its temperature, occasioned by the equalizing influence of the ocean. Although the 

 places of observation arc on a low level, and in the extreme south part of the State, the 

 greate-i heal of summer is 1^° less on an average, than in other parts of the State which 

 arc further north and more elevated. On the contrary, the extreme cold of winter is less 

 by 10 3 to 18°, and has been so uniformly every year for the past fifteen ) ear*.
