TRANSACTIONS OF THE 



Average Annual and Seasonal Temperature in Sacramento. 



The statement below shows the average temperature, for each year, for 

 thirty-six years; also the spring, summer, autumn, and winter temper- 

 ature for the same time. The coldest year, inferring from the average 

 temperature, was that of 1880, 57.2°; the warmest was 1864, 62.8°; the 

 mean average for the past thirty-six years, 60.2°, showing the coldest to 

 have been 8° below the mean average, while the warmest year was that of 

 1864, when it was 2.6° above the mean average of thirty-six years. By 

 careful study of the table, there will be noticed but a slight difference 

 between the coldest and the warmest year, as compared with an average of 

 thirty-six years; generally not more than 3°. Therefore, we might safely 

 say that the average temperature of any year is not likely to vary more 

 than 3° from 60° either way, between the hottest and coldest year, as com- 

 pared with the mean average temperature of many years :
