Sir

I am pleased with your observations and returns but there are one or two things which you appear not to understand.

The Sum of the columns is the arithmetical sum of all the observations which is limited by the number of days on which observations were taken to find the ?? or it is the total number of degrees during the month for the sum: divided by number of observations for ?? when in reference to the directions of wind if you observe it more than once in the day it is necessary to give the time of each observation. And I also observe that you sometimes take out the amount of evaporation incorrectly: If you correct these matters your returns will then be one of the most satisfactory that I receive from the country observers.

I have the honor to be
