508 PROFESSOR HENRY A. MIERS : AN ENQUIRY INTO 
In Series II., 20 cub. centims. of a saturated solution were examined and dduted 
down by successive additions of 2, 4, 6, or 8 cub. centims. of water. This series of 
observations was made in a single day. The results are given in Table XIII. and are 
represented by dots in Diagram IV, 
In Series III., 10 cub. centims. of a supersaturated solution, weighing 14-39 grammes 
and containing 7-843 grammes of substance, were placed in the trough and dduted by 
successive additions of 2 cub. centims. of water up to No. 12 ; warm water being used 
up to No. 5; water at the ordinary temperature from No. 6 onwards; Nos. 13 and 
14 were made after the addition of 4 cub. centims. each. 
The results are given in Table XIV. and are represented by dots in Diagram lY. 
The irregularity in the series of crosses is fully accounted for liy the break in the 
continuity of the observations.
