The numbers opposite beginnings of lines refer to Pigeon Nos. of tables. The graphs presented in Figures 4 to 45, inclusive, are based upon the weights of the pigeons recorded at approximately weekly intervals during the experiments, except that the weight of any bird suffering from a congestion of food in its crop, an early symptom of poly- neuritis, was not recorded. Since most pigeons that develop poly- neuritis suffer from this condition of the crop, it was found to be inadvisable to weigh each bird at the time it developed polyneuritis. For this reason, then, the graph of a pigeon usually indicates a shorter period than the survival period for the same bird recorded in the table. Occasionally a graph may indicate a slightly longer period than the survival period shown in the table. In such cases the crop of the bird was normal and the last weighing was made a few days after the development of the disease. The percentage change in weight of each pigeon, as indicated in the tables, is based upon the initial weight and upon the last normal weight as shown in the graph for the s
