PROFESSOR HENRY A. MIERS; AN ENQUIRY INTO 
►Sti’ongiy supersatiiratecl solutions of unknown constitution were next examined by 
the total reflection method with the prism of angle 44° 58' and index 1-51704. 
In Series I., 50 cub. centims. of a supersaturated solution were placed m the 
trough aud diluted by successive additions of 2 cub. centims. of water. The results 
are given in Table V., and are represented by dots in Tliagiam II. 
of the substance. 
50 cub. centims. of the solution Sj were diluted with 25 cub. centims. of water ; and 
50 cub. centims. of this new solution {S) were then examined in the trougli and 
diluted Ijy successive additions of 5 cub. centims. of water. The results are given in 
Table VI., and are represented by dots in Diagram II. : this set should, of course, be 
continuous witli the preceding ; they are connected by a dotted liim on the diagram. 
In Series IT, 50 cub. centims. of a supersaturated solution So v'ere diluted^ by 
successive additions of 5 cub. centims. of water. The results are given m Table A IT, 
and are represented by crosses in Diagram II. 
Tlie strength of these solutions is obtained liy assuming that No. 3 has the same 
coiistitutioulis No. 6 ill Table V., the two having nearly the same refractive index.
