INFLUENCE OF RELATIVE HUMIDITY AND MOISTURE CONTENT. 5 
The percentage yields indicated by the curves shown in the accom- 
panying figures are based on the weight of the cleaned and scoured 
wheat samples before the addition of the temper water. 
INFLUENCE OF RELATIVE HUMIDITY ON TOTAL YIELD OF MILL 
PRODUCTS AND INVISIBLE LOSS.

the mill. 
erted on yields by the variation in the quantity of temper water 
which differences in the original moisture content of the various 
samples made it necessary to add in order to temper each of 15 per cent 
moisture, the curve shown represents the combined effect of relative
