From the average thus obtained for each day in the year, I 

 obtain averages for each month, for each season, and for the year, 

 as follows : 



Averao^e for January 25.29 July 70.28 



February .. 25.39 August 68.08 



March 32.26 September. 60.47 



April 43.21 October... 49.66 



May 55.66 November. 39.12 



. " June 64.93 December. 25.56 



From which it appears, as we should expect, that July is the 

 hottest month in the average, and January the coldest. 

 The average for the season is as follows : 



Spring 44. 2 1 Autumn ._ 49.52 



Summer 67.68 Winter.. 25.41 



The average for the year is found to be 47.20 deg. This is 

 obtained, however, not in the usual way of adding together the 

 averages of the months and dividing by twelve, or the average of 

 the half months and dividing by twenty-four, but by taking the 

 averao-e for the davs and dividino^ bv 365, nes^lectino^ the one- 

 fourth day due to February on account of the bissextile addition. 

 I then made an average for each week in the year, which, together 

 with some other computations, I have also thrown into the accom- 

 panying tabular form. In the Jii^st column is the day of the month 

 on which the week ends ; in the second is the average for the 

 week, obtained from the observations and the above averages for 

 the days in the 3^ear. For the tJiird column I have computed 

 what the temperature for the day for each seventh day (beginning 

 with Jan. 4th) should be, provided the 47.20 deg. were distributed 

 according to astronomical influences alone ; namely, the sun's alti- 

 tude and the length of the day. For a fourth column I have, in 

 like manner, computed what the temperature for the day for each 

 seventh day, beginning likewise with the 4th of January, would
