4. Period IT. — The pumpkin seeds used during this experiment were 
obtained from a seed grower. The roasting was done after the hulls 
were removed. The hull-free seeds were placed in a flat glass dish and kept 
in a dry-heat oven for three hours at a temperature of 110° F. or 43° C. 
The table below shows the quantities of pumpkin seeds ingested at each 
meal during the experimental Period II.

were also used in Period II of this experiment.

6. Discussion. — To reduce the effect of the variation factor upon the 
study of results and to obtain a more satisfactory comparison the hy- 
pothetical mean of results of each period was computed.
