LETTER OF TRANSMITTAL 



University of Illinois, June, 1912. 

 DR. EUGENE DAVENPORT, 



Director of the Agricultural Experiment Station. 



Sir : I have the honor to transmit and recommend for publication the 

 accompanying paper prepared under my direction by Chas. F. Briscoe, Ph.D., 

 upon the FATE OF TUBERCLE BACILLI OUTSIDE THE ANIMAL BODY. 



This is a companion bulletin with No. 149 of the . University of Illinois 

 Agricultural Experiment Station issued under date of February, 1911, entitled 

 TUBERCULOSIS or FARM ANIMALS, by Chas. F. Briscoe and W. J. MacNeal. 

 That bulletin was based upon a general study of the disease in bovine ani- 

 mals its characteristics, modes of dissemination and infection, methods of 

 recognition and prevention, and the relation to tuberculosis in man. 



The import of the present paper is well expressed in the title, with the 

 understanding that the studies were made principally upon the bovine type of 

 the causative organism. Much previous work had been done upon the same 

 subject, as is indicated in the literature herein cited, but important contribu- 

 tions to existent knowledge are made in the results of the experiments em- 

 bodied in this publication, while earlier announcements have been confirmed 

 or disproved. The whole matter is of such tremendous significance that any 

 additions to knowledge and any further dissemination of knowledge upon the 

 subject is of wide and vital importance. The information here presented will 

 be welcomed by specialists, sanitarians, and the general public. 



T. J. BURRILL, 

 Chief in Botany (including Bacteriology).
