At the present time no subject is attracting as much attention from investigators as the relation of bovine and human tubercle to each other and to man and animals. To what extent man can be infected with tuberculosis by cattle, or cattle by man, is as yet only partially answered, and hence any contribution which is in any way likely to settle, or help to settle, the question, is welcome. In Bulletin No. 57, of the Arkansas Experiment Station, Dr. R. R. Dinwiddie reports some experimental work he has done, and gives his deductions. These experiments were made on various animals, the main object being to test the susceptibility of cattle toward human sputa, and incidentally to make a comparative test with the bovine tubercular material also. The results as given by the investigator, while not of startling importance, go to corroborate the generally prevailing views. He summarizes the matter
