80 TWENTIETH ANNUAL REPORT ON THE STATE CABINET, 



furnisli data from which other and most important inferences 

 could be drawn ; and as illustrating several such points, and as a 

 slight contribution to our knowledge on local climatology, I give 

 in a tabular form the average temperature for every day in the 

 year, with the maximum of heat and of cold for the day as ob- 

 served in the observatory in this place for a period extending 

 over twelve years, from 1854 to 1865 inclusive. During the first 

 year the records are incomplete ; still, however, if any one should 

 wish hereafter to continue the average here given, he has only to 

 multiply that which is given by twelve, and add that for any 

 other year and divide the amount by thirteen.
