1 Found to be slightly fermented. 
From these data we note that drying even at this lower temperature 
(70° C.— 75° C.) for a period of 20 hours, gives results much higher 
than those obtained from the specific gravity estimations; and, further, 
the percentages of moisture — or rather of loss — increase with con- 
tinued heating, though not so rapidly as when a temperature of 98° C. 
is used (see Table L.). 
Drying on (a) ASBESTOS, AND (b) SAND, IN PLATINUM DISHES, 
IN PARTIAL Vacuum AT 70° C. 
The apparatus used in these trials was exceedingly simple. A 
tubulated desiccator was placed inside the steam bath (the same as 
used in the foregoing experiment) and connected as shown in the 
illustration with an exhaust pump attached to the water service. With a 
current of dry air at the rate of one bubble per second being drawn 
through the desiccator, a vacuum of approximately 8 inches was main- 
tained. The temperature of 70° C. was without difficulty kept con- 
stant for a week or more at a time by almost filling the bath with 
water and arranging a series of small gas jets (from an S-burner) at 
a distance of 3 to 4 inches from the bottom of the bath. The flames 
were protected from draughts by a casing of asbestos board. 
The absorbent materials were sand and asbestos, and platinum 
dishes (flat and round bottoms) were used in the place of glass tubes.
