DIRECTIONS FOB USE. Suppose the specific gravity found at 18 C., to be T030, this 

 is represented in the Table, on the horizontal line at the top, by the last two figures, viz. 

 30. Under the figure 30, the number corresponding to the temperature 18 C. (in the 

 vertical column at the sides of the table) is found, which in this case is 30'6, and represents 

 the specific gravity at 15 C.
