sponsible for the physiological disturbances as already described, Dr. 
Bunting of the Medical School of the University, kindly consented to 
make a histological study of the tissues from a number of the abnormal 
calves. In general no striking lesions were revealed. Livers and kid- 
neys showed some degeneration (hydropic) changes, but the nervous 
tissues gave the most evidence of the presence of an excessive amount 
of fluid — a condition of oedema. This histological picture was anal-

Successful reproduction in the presence of the embryo. A ration of corn meal 4 parts, 
corn starch 1 part, wheat embryo 2 parts, corn stover 7 parts. At least for the first gesta- 
tion the 'antidotal' properties of corn meal and corn stover were sufficient to overcome the 
toxic effect of the wheat embryo. Without the corn meal and with only wheat embryo, 
starch, and corn stover in the ration reproduction would have been premature and the calf 
either dead or markedly undersize (see figure 1). 
ogous to that of beri beri, the result of feeding polished rice, and it also 
simulated, if it was not identical, with that obtained from the spinal 
cord of pigs on certain rations as described in a previous publication.^ 
The oedema was observed between the membranes covering the cord, 
around the blood vessels and around the nerve cells. In these instances 
the nerve cell and their nuclei were shrunken, the latter staining more 
intensely than normally. No abnomalities in medullation of the fibers 
of the cord as demonstrable by the Weigert stain were observed. While 
the observations did not point to anything especially characteristic it
