Average body temperature xo.ii ” C. Difference between average body temperature and air temperature 
4.7 “C. 
TOMPJSRATURE OF THE ITALIAN WORKERS 
A striking result noted in the tables was the small range in the differ¬ 
ences between the maximum and minimum temperature readings at the 
different temperatures, as is shown in Table II. This is especially notice¬ 
able at the higher temperatures. In Table I there is a range of 5.5° C. 
between the maximum and minimum temperatures in the readings of 
100 bees. We find in Table II a variation in the differences from 9° at 
21.4® to 1.5® at 27® and 43.5° with the difference of 2.5® at the tem¬ 
peratures of 30.5®, 35®, 52®, and 58®.
