XI, B, 3 Gibson and Concepcion: Development of Neuritis 131 



centimeters, respectively. The growth curves for the dogs and 

 pigs are given in the accompanying charts. 



Our experiments have indicated that the antineuritic vita- 

 mine is present in milk in slight amounts only and that the 

 continued feeding of either fresh milk or autoclaved milk to 

 animals (dogs and pigs) without suitable additions to the diet 

 induces certain beriberi symptoms — namely, degeneration of the 

 peripheral nerves, persistant oedema, and aphonia. There is no 

 evidence that autoclaving the milk for two hours has in any way 

 affected its nutritive value. Not even scorbutic changes have 

 been observed. At the best, the antineuritic powers of the 

 milk are so slight that in infant feeding the diet should be 

 extended as soon as possible. The young of healthy mothers 

 probably come into the world with a reserve supply of the 

 vitamine substances sufficient to tide them over nutritively 

 until the time when, under natural conditions of life, they would 

 begin to eat other foodstuffs.
