Reaction Time.

Through the courtesy and kind co-operation of Dr. Charles H. Judd, in charge of the Yale Psychological Laboratory, these students were subjected to the same careful tests during the five months of their experiment as were applied to the soldier detail. The results which are presented in the following report, kindly prepared by Dr. Judd, indicate quite clearly that there was no general nervous change in the reactors as a result of the low proteid diet. The data presented by Dr. Judd in this connection will be found in the accompanying tables, which, while indicating no noticeable improvement in the nervous condition of the men, make it quite plain that no deterioration whatever occurred as the result of the lowered proteid metabolism.
