Dates of Maximum Temperature at Different Depths . — The in- 
tersections of the curves give, as above shown, an indication of the 
date of maximum temperature at the particular depth. In Table 
XII. will he found the depths corresponding to the principal 
intersections and the mean dates. The actual dates of maximum 
temperature will always be a day or two later than the mean dates. 
The number of observations is too small to enable us to say what 
the maximum temperature at these depths has been.
