I subsequently made a second series of experiments to determine the reduced value 
for glass 1, which gave the following results : — 
Temperature of the Air 19°-9-19°-8.

The mean of these two means, 0-657 and 0 , 645, gives as the reduced value in water 
of glass 1, 0-651 grm. 
To obtain the water value for glass 2, I made the following determinations : —

The reduced value for glass 2 is hence = 0487 grm. This glass broke before I 
made a second series of experiments to ascertain its reduced value. 
I made two series of experiments to determine the reduced value of glass 3. The 
first gave the following results : — 
Temperature of the Air 19 0, 3-19°-5.
