* ‘* Middlings ” is millers’ term for fine flours. 
It is evident, as is well known, that the phosphorus compounds 
of the wheat kernel are found mainly in the outer coatings and 
germ from which are derived the bran and middlings. As the bran 
phosphorus is mostly contained in the compound phytin, it is self- 
evident that this substance exists in much larger proportion in the 
whole wheat bread than in fine flour. These statements are offered 
as suggesting a problem for further study. 
A pharmacological study of the compound phytin—In view of 
the possible pharmacological properties of this compound, as in- 
dicated in these experiments, it was thought to be very desirable 
that experienced investigators should undertake a study of its 
physiological influence. Correspondence was entered into with Dr. 
R. H. Chittenden of Yale University and he very kindly consented 
to undertake pharmacological observations with this substance. 
There was prepared, therefore, in our laboratory the anhydrooxy- 
methylenediphosphoric acid, which is phytin freed from its bases, a 
quantity of which was sent to Dr. Chittenden. We understand that 
the studies indicated are now in progress under the direction of Dr. 
L. B, Mendel. | 
The increased flow of urine, caused by feeding the unwashed 
bran ration.—Several points need consideration in this connection. 
Marked changes in temperature undoubtedly have an influence on 
urine secretion but as both of these animals stood in a room which 
was warmed to the point of comfort by artificial means, this factor 
hardly needs consideration. It has already been made clear that
