»The drip was collected and weighed but once a day. The volume was roughly observed at 
1 p.m., 7 p.m., and 7 a.m., and this volume taken as a rough indication of the actual weight of drip 
for the different periods. The small amount of drip observed at 7 a. in. was divided equally between 
the two night periods. The figures in this column also include the perspiration in clothes, which 
amounted to 21, 23.8, 20.4, 18.3, 15.3, and 18.8 grams on the successive days of the series. The amount 
for each day has been divided equally between the periods ending at 1 p. m. and 7 p. m.
