The author gives a preliminary note of a number of experiments on the rôle of suctorial insects in the dissemination of anthrax. The experiments were made with an artificially infected guineapig, which died of the disease upon the third day. The flies were applied two "and a half hours to a few minutes before the death of the animal. Guinea-pigs were used to receive the infective bites of Stomoxys calcitrans and Tabanus striatus. With both species the infection was successfully transferred by the direct method in which the flies were interrupted while feeding on the sick animal. The exposed animals died during the evening of the third day, typical symptoms of anthrax being exhibited, and in addition a gelatinous and haemorrhagic oedema was observed in the subcutaneous region of the area upon which the flies were applied in biting. The agar cultures when iniected reproduced the disease in guineapigs with fatal results. Similar results were obtained in all essentials when horse flies were used to transfer the disease. A series of experiments is at present being conducted with anthrax in cattle and horses, guineapigs and other rodents being employed as intermediate hosts for the disease.
