July 15,1921 Effects of Some Cucurbit a Seeds on Animal Metabolism 533 
The feeding of the pumpkin was done regularly three times a day, by 
hand. Considering the young age of the experimental animals it was 
expected that they would consume 5 pounds of pumpkin per 100 pounds 
live weight per day, but the first week revealed that lot I would clean up 
the seeds at first and not go very readily after the pulp, while lot III 
would consume a little over 4 pounds per day per 100 pounds live weight. 
However, beginning with the second week the total weight of the entire 
pumpkin consumed by lot I would be equal to the total weight of pumpkin 
less the seeds consumed by lot III. During the first three weeks of this 
period considerable quantities of the whole seeds were found in the feces. 
Later on, however, this condition became rare. Toward the end of period 
I it became evident that pig 637 of lot II was gaining out of proportion as 
compared with the rest of the lot; on the other hand, pig 639 was a runt, 
being at a standstill. Pig 642 of lot III began to develop a rupture at 
the umbilicus. Before beginning period II these three pigs were dis¬ 
carded. To balance the numbers in the pens, pig 626 of lot I was trans¬ 
ferred to pen Nc/. 3, leaving five pigs per pen. Every effort was made to 
keep the lots as nearly uniform as possible. 
The pigs were weighed weekly. The feeds of the self-feeders were 
weighed at the close of each week, and the weekly consumption of the 
feeding stuffs was thus obtained. For the computation of the consump¬ 
tion and the gain or loss during the week per 100 pounds live weight the 
initial weight of each lot of each week served as the basis for calculation. 
During the second week of period I lot III consumed relatively less 
corn than each of the first two lots; hence, the gain of lot III was affected. 
With the exception of pig 630, lot I gave more favorable results through¬ 
out the entire period than either of the other two lots. 
Period II.—This period began November 27 at noon and closed 
December 11 at noon. The object during this period was to compare 
results obtained by feeding known quantities of ground “cannery” seeds 
mixed with the chopped pumpkin (containing 10.65 P er cent seeds) with 
the results obtained by feeding the chopped pumpkin (containing 10.65 
per cent seeds) alone. Lot I received the mixture of pumpkin products, 
fed- by hand, besides the feed contained in the self-feeder ad libitum. 
Lot II was on the self-feeder only, serving as a control. Lot III received 
chopped pumpkin (containing 10.65 P er cent seeds) fed by hand, besides 
the foods of the self-feeder ad libitum. 
Tables XIV to XVI show the results obtained during period II. 
The feeding of the pumpkins to both lots was done regularly three 
times a day as during period I. Pig 630 of lot I, although he was a poor 
gainer and showed symptoms of indigestion at the end of period I and 
continued in this condition into period II, was retained to await further 
development of his illness. During the second week of period II, pig 
633 of the control lot (lot II) began to scour and vomit and lost 11 
pounds of her weight. The cause of sickness of pig 630, therefore,
