TUBERCULOSIS, one of the most widespread and deadly diseases 

 with which we have to deal, not in this country only, but in 

 the whole of Northern Europe, has now certainly been proved 

 to demonstration to be due to the presence of a specific 

 micro-organism. Almost innumerable researches have been 

 carried on with the object of finding out and piecing to- 

 gether the various facts in the life-history of this organism, 

 the products to which it gives rise, the conditions under which 

 it can multiply in the human body and in the animal body, 

 the nature of the very grave changes produced in the tissues, 

 the mode of transmission directly and indirectly from one 

 body to another, and, last, but not least, the possibility of 

 combating the ravages made on the body by this organism, 

 by interfering with its growth or retarding its development, 

 either outside the body or after its introduction into the 

 tissues. 



Tuberculosis and Phthisis or Consumption account for 

 such an enormous percentage of deaths in our colder north- 

 ern latitudes, that the subject has come to be one of intense 

 interest, not only to physicians and surgeons, but to all well- 

 educated people, and the subject of the treatment of tuber- 

 culosis is unfortunately perhaps for patients taken up
