Thermometers 500, 501, and 502 had nearly spherical bulbs, whose mean 
diameters were respectively about 9°16, 10°54, and 11°67 millimetres. 
The observa- 
were kept, throughout the observations, in an upright position. 
tions themselves commenced very shortly after the customary immersion in 
boiling water. The equations are— 
Yano = 2AT(‘92125)" + 220(-045)", 
Yoon = ‘210(-86875)" + -200(-03838)", 
Yoon = '268(90986)* + °243(-14482)", 
the unit of x being 30 days.
