 When it is remembered that Vitamin B is so generally accepted as of great importance, the position of the pecan as a safe source of Vitamin B, accepted by the leading nutritionists, is well worth noting. In 1920, Cajori stressed the advantages of the pecan in supplying Vitamin B, and researches since then have emphasized the importance of that statement. He showed that one gram of pecan kernels per day furnished suf- ficient quantity of Vitamin B for the normal growth of the white rats, in his report in the Journal of Biological Chemistry.

Turning to the recent experiments by Salmon & Livingstone we find further confirmation of his statement. Their tests were made on both pigeons and rats, with every care to check their accuracy. Two pigeons which were fed on-a diet lacking in Vitamin B—the anti-neuritic vitamin—lost weight rapidly and died of polyneuritis in 18 to 28 days.

- The other birds were fed pecan kernel! in vary- ing ratio and observations made regarding the development of polyneuritis. Those receiving but a half gram to a gram daily declined slowly, but not as fast as those entirely lacking pecans. As definite symptoms of polyneuritis developed, the pigeons were restored by administering pecan kernel, with an increase in the daily dose. In most cases 2 to 3 grams of pecan restored these
