 Coward & Drummond reported an abundance of Vitamin B in nuts; but in walnuts, almonds, brazil nuts, peanuts and Barcelona nuts did not report any material amount of Vitamin A. In this research for Vitamin A they had not examined the pecan.

The most recent research conducted discloses that the pecan does contain an appreciable con- tent of Vitamin A—as shown by the report of the Salmon & Livingstone experiments in the Mareh 1925 issue of the Journal of Home Economics. Vitamin A is present also in butter, milk, cream, ege yolks and in greens-—-therefore the use of peeans in the dietary in combination with those foods, as found in this recipe book, is ebviously a double safeguard assuring. ample supply of this needed Vitamin A, and of the associated Vitamin D, which is now considered as more closely affect- ing rickets. The high lime content of the pecan is again advantageous here.

It is significant also that in reporting their experiments on white rats which led to the dis- covery of an appreciable content of Vitamin A in pecans, Salmon & Livingstone directed attention to the fact that the addition of 50% of cod liver oi] or butter to the ration did not perceptibly better the growth, showing that the slowing up in rate of growth had not been due to a lack of fat soluble vitamins.
