MEDICAL MICROSCOPY. 



Work of the Mich. Board of Health in 1894.— Tlie subject 

 of tuberculosis in animals as a cause of tubercular diseases in 

 man, is being presented to the people. A survey of the cat- 

 tle and milk in different parts of this State will show in what 

 way and to what extent the health and lives of the people are 

 endangered by tuberculous meat and milk. Dr Gray reports 

 that he has conferred with veterinary surgeons in Pontiac and 

 Detroit, has visited the health department in Detroit, that he^ 

 has corresponded on this subject with the three members of 

 the State Live Stock Commission. Hon. J. J. Woodman has 

 said that the presence of tuberculosis in animals is not being 

 reported to the State Live Stock Commission. 



Dr. Baker says he has conferred with the State Veterinarian, 

 who advised further and personal conference by this Board with 

 the State Live Stock Commission. Dr. Baker quotes from the 

 last report of the commission relative to tuberculosis — " It is be- 

 yond question both infectious and contagious, particularly in 

 the pulmonary developement or consumption of the lungs." 

 * * * "Years of added experience and careful observation 

 lead us to the conclusion that tlie annual losses among Mich- 

 igan cattle from tuberculosis are much greater than from all 

 the other contagious diseases affecting our domestic animals, 

 and that the disease is steadily increasing. We have given the 

 subject ver}' careful thought and consideration, and have as 

 yet failed to find a satisfactory plan for its treatment or exterm- 

 ination." * * * " it,^ a.s yet, is one of the unsolved prob- 

 lems, lying all in front and like some bridges, in our pathwa}^ 

 the day is not far distant when an attempt must be made to 

 cross." Secretary Baker thought that now is the time to make 

 the attempt to "cross the bridge," and earnestly hoped that the 

 State Live Stock Commission would co-operate in the effort for 

 the restriction and prevention of tuberculosis in animals and in 

 man. It was voted that the President be requested to call a 

 special meeting of this State Board of Health at such time as 

 arrangements can be made, for a joint meeting with the State 

 Live Stock Commission, to consider the subject of the restriction 

 of tuberculosis in animals and in man. 



As chairman of the Standing Committee on "P^pidemic and 

 Communicable Diseases," Prof. Vaughan made a n^port on the 

 subject of the restriction of tuberculosis in man by means of a 

 proposed State Hospital for Consumptives, this subject having
