centimetres being mixed with boiled ground rice. The results of the majority of experiments are given in Table NOTI. Others were made from time to time, at varying periods, yielding similar results, and therefore need not be recorded.
The conclusions to be drawn from these experiments are:
(1) Feeding guinea pigs with broth cultures of the B. pestis frequently induces the disease.
(2) The type of the disease produced is either acute septicaemic plague, bubonic plague, or intestinal plague.
(3) The type of the disease is to a certain extent dependent upon the dose, but this is found to be very variable.
(4) The production of intestinal plague by broth cultures is very uncertain and obtains only as a complicating accompaniment.
Series No. II.
A similar series of experiments was made.
