ABOUT THE 20tH OF DECEMBER, 1836. 



133 



In order to determine the dependence of the temperature upon latitude and 

 longitude, I classified the observations as below, placing the most western ob- 

 servations on the left and the eastern on the right, and arranging each in the 

 order of latitude. The table shows the greatest heat observed during the storm. 

 and the greatest cold immediately succeeding it.

The average of the maxima at the eastern stations is about three and a half 

 degrees greater than at the western; and the average of the minima fourteen 

 degrees greater. It is remarkable that, with the exception of Quebec, the only 

 stations where the thermometer fell below zero were in the north-west quarter 

 of the United States, and would be cut off by a line joining Detroit and St, 

 Louis. 



III. Rain — amount, &c. 



The following table shows the amount of rain which fell at the different sta- 

 tions, with the time of commencement and termination, so far as the same 

 could be collected from the registers.
