Table II.—Results of Individual Experiments. 
Explanat ion of Symbols used in the Table. 
6 — Reading of divided circle, during experiment. 
= Zero reading of divided circle. 
H = Height of wet surface of stationary cylinder. 
Y = Revolutions per minute of revolving cylinder. 
T = Temperature, in degrees Centigrade. 
Up to Experiment 97 torsion-wire No. (l) was in use. Experiments 98 to 208 
were made with torsion-wire No. (2). 
No. (1) was a brass wire. No. (2) was a nickel wire.
