From Figure 2, it appears that for HC/ the present results agree bet- 
ter with Loomis’s than with Jones’s. In the case of H,SO,, the agreement 
between them all is very good, considering that, for n equal to 0°01, one 
scale division represents only 0°0001 degree in the actual depression (6). 
This sensitiveness, of course, diminishes as the concentration increases, so 
that, for n equal to 0°10, one scale division corresponds to 0°001 degree in 
the depression (6). The regularity of the present values is very gratify- 
ing especially when compared with the HC/ values of Loomis and Jones. 
The HCl curve presents a minimum value of 6/n, about where n equals 
0-01 ; this also appears at about the same point in Loomis’s results.
