decided rise in temperature. Healthy animals show no reaction at all 

 or at most a very slight reaction. No animal with a normal tempera- 

 tuire of over 103 is fit to test for tuberculosis. 



Prevention of Tuberculosis 



Under ordinary conditions a course of treatment is not advisable be- 

 cause of the danger of spreading the disease to oth^r stock. Out door 

 life night and day with an open shed for shelter is probably the most 

 effective treatment. 



All calves using milk of tuberculosis cows should have their milk 

 boiled, and such milk should not be used for family use. 



Barns where tuberculosis cattle have been should be thoroughly 

 cleaned after the cattle are removed and all parts oi the building washeid 

 with 1 gallon of formaldehyde to twenty of water. New cattle should 

 not be purchased unless they have had the tuberculin test and passed. 

 If more people required it there would soon be a great reduction in tu- 

 berculosis. 



Facts About Tuberculosis 



I One seventh of the human deaths are due to tuberculosis. 



II That scientific men have made sufficient study of the relation of 

 bovine and human tubdrculosis to draw an accurate Qonclusion. 



in Out of authentic tests, east of the Missouri river, covering 15 

 years, approximately 10 per cent of the number of cattle tested have 

 proven tubelrcular. 



IV That bovine or the kind of tuberculosis effecting cattle is fatal 

 quite often to children, fed cows' milk. 



V There are con^ant opporttunities of transmitting tubiBiV:ulosis 

 to childlren. 



VI The germs are in the air of the buildings housing tuberculin cows 



and often get in clean cows milk. 



VII Investigations have shown that about two tuberculin cows out 

 of nine pass the germs in the milk as it is drawn, from the udder. 



Relation of Bovine Tuberculosis to the Human Family 

 Dr. Park ,of the New York City board of health has probably made 

 a more extensive study of the relation of bovine tuberculosis to the hu- 

 man family than any one else in the United States. His yedrs of study 

 are briefly summarized as follows. 



15 cases of tuberculosis out of 955 cases of tuberculosis in adults
