VITAMINE CONTENT OF FOODSTUFFS

(701) used decorticated barley to produce beriberi. Steenbock, Kent 

 and Gross (702) observed that for rats, barley, like other cereals, was 

 deficient in vitamine A, protein and salts. 



Oats 



McCollum, Simmonds and Pitz (I.e. 372) regarded the composition 

 of oats as unfavorable for the nutrition of animals. Tested on rats, 

 it showed a lack of vitamine A, protein and salts. This applies much 

 less to pigeons, as we ourselves have shown. 



Wheat 



Voegthn and Myers (I.e. 271) 

 believed that vitamine is found ex- 

 clusively in the germ; we have 

 already published our findings in 

 this respect (I.e. 271). How the 

 various parts of the wheat kernel 

 are related to each other, we may 

 see from the following diagram, 

 taken from the work of the above 

 investigators, from which we may 

 note the method of sectioning used 

 by them in their experiment on 

 the localization of vitamine B. 

 McCollum, Simmonds and Pitz 

 (703) investigated, in particular, 

 the vitamine value of wheat germ. 

 Qualitatively considered, this por- 

 tion of the wheat has been shown to be adequate, but for practical 

 reasons, an addition of salts must be given. Vitamine B occurs 

 in the germ in large quantities; vitamine A, on the other hand, 

 in smaller amounts. Osborne and Mendel (704) investigated the 

 nutritive value of various milling products of wheat kernels, and 

 did not believe in the exclusive localization of vitamine B in the 

 germ. The contiguous portion was also rich in vitamine B, as was 

 also the periphery of the kernel, the endosperm and bran not con- 

 taining very much.
