but was allowed only four to rear, in order not to overtax her mammary 
capacity. These four young were successfully reared to weaning age. 
Experiment II, Lot L—(Charted in fig. 2.) This experiment shows 
the successful normal growth of the young of rat 200 to maturity. These 
animals were permitted to interbreed, and it will be noted that rat 471 
reared the third generation successfully. Rat 200 was then bred to one 
of her sons and successfully reared all the eight young which she brought 
forth at birth. (Not shown on fig. 2.) Our efforts to substitute the 
uncooked seed for the cooked met with failure, due evidently to the toxic 
principle in the raw seed.

milk. Dotted lines represent normal curves of growth. Y~young. 
Experiment III, Lot CXIII.—(Charted in fig. 3.) On a ration com¬ 
posed of 40 per cent velvet bean hay (finely ground whole plant), 60 per 
cent starch, and a liberal supply of skimmed milk, rat 454 successfully 
reared the four young to which she gave birth.

Experiments IV, V, Lot CXIII.—(Charted in fig. 4 and 5.) This 
experiment showed that quite satisfactory growth was secured through 
the second and third generations on this simple and monotonous ration 
of whole plant 40, starch 60, and a liberal supply of skimmed milk. We 
attribute the poorer showing of the animals on Figure 4 to hot weather and 
less consumption of milk due to rapid souring. The whole plant and 
starch mixture was readily eaten by all of our animals on this ration.
