and animal inoculation the glands of cattle which had reacted to the 

 tuberculin test, but in which lesions were not found by ordinary 

 post-mortem examination. In more than half of the cases tubercle 

 bacilli were positively identified, showing that tuberculosis was really 

 present in these carcasses in an incipient form, the lesions being too 

 slight for detection by ordinary post-rnortem examination. The per- 

 centage of accuracy of the tuberculin test may be said, therefore, to 

 be even higher than indicated by the figures previously stated. 



REPORT OP INTERNATIONAL COMMISSION ON CONTROL OF BOVINE 



TUBERCULOSIS. 



In this connection, reference should be made to the very valuable 

 report recently submitted by the International Commission on the 

 Control of Bovine Tuberculosis, an advance typewritten copy of 

 which is in possession of the committee (Appendix AC), the report 

 having not yet been printed for distribution. The report was not 

 only agreed to without dissent by the members of the commission, 

 but received subsequently the unanimous approval of the American 

 Veterinary Medical Association at its recent convention in San Fran- 

 cisco. The labors of the commission extended over the period of a 

 year. 



At the meeting of the American Veterinary Association at Chi- 

 cago, 111., in September, 1909, the following gentlemen were con- 

 stituted an international commission to study the methods of the con- 

 trol of bovine tuberculosis and to report its conclusions at the next 

 annual meeting of the association. In order that all interests af- 

 fected might be adequately represented, the commission embraced 

 among its personnel Senator W. C. Edwards, a member of the Ca- 

 nadian Parliament and one of the most extensive live-stock breeders 

 of the Dominion; J. J. Ferguson, chief of the animal husbandry 

 work of Swift & Co., Chicago, 111.; J. W. Flavelle, head of one of 

 the large packing companies of Canada; W. D. Hoard, editor of 

 Hoard's Dairyman (a representative journal of the dairy interests) 

 and a former governor of Wisconsin; C. A. Hodgetts, health officer 

 of the Province of Ontario, Canada; J. N. Herty, secretary of the 

 Indiana State Board of Health; Dr. John R. Mohler, chief of the 

 pathological division, Bureau of Animal Industry, United States 

 Department of Agriculture; V. A. Moore, professor of pathology, 

 Cornell University; M. P. Ravenel, professor of bacteriology, Uni- 

 versity of Wisconsin; M. H. Reynolds, professor of bacteriological 

 science, University of Minnesota ; E. C. Schroeder, superintendent of 

 the Bethesda Experiment Station, United States Department of Ag- 

 riculture; T. W. Tomlinson, secretary of the American National 

 Live Stock Association ; F. Torrance, professor of bacteriological sci- 

 ence, University of Manitoba; and J. G. Rutherford, veterinary 

 director general of Canada. A cursory inspection of the make-up of 

 this commission gives absolute assurance of the soundness of its con- 

 clusions, and breadth of view is guaranteed by the diversity of inter- 

 ests represented. Notwithstanding the participation in the labors of 

 the commission, of recognized representatives of the packing and 

 dairy interests, the report of the commission was a unanimous one. 

 It is prefaced with a reference to the great economic and sanitary
