TABLE IX. 



Showing the Mean Monthly and Annual Temperature (Fahrenheit) at 

 Different Places over the Globe. 



Note. — Under Column of "Hours of Observation," the A.M. Observations are placed before the colon [:], the 

 P.M. after it. The means in the Table are the arithmetic means for the times of observation. 

 The expression 7 : 1, 9, 9 signifies that, in striking the means, the observations at 9 P.M. have 

 been taken twice ; and m, 8 : 2, 8 that the means are the averages of the daily Minimum, 8 a.m., 

 and 2 and 8 p.m., &c. In the same column " M.m." signifies that the Mean Temperature is 

 deduced from the Maximum (m) and Minimum (m) Observations, "M.T."that the Means have been 

 reduced to Approximate Mean Temperatures. A Minus sign before Latitudes indicates Latitude 

 South, and before Longitudes, Longitude West. In the last column are entered the corrections 

 which have been applied in constructing the Table.
