1 Obtained for each month by dividing the sum of the absolute maxima during the period 

 covered by observations by the number of years. The annual mean maximum for each station 

 represents the mean of the monthly mean maxima. The years during which measurements of 

 temperature have been taken at the several stations are: Norfolk, 1871 to 1898; Cape Henry, 1874 

 to 1898: Hatteras. 1881 to 1898; Wilmington. 1871 to 1898. 



3 Obtained in the same manner as the mean maxima.
