252 BACTERIA. 



supported to be able to oust the bacillary theory from its 

 present position. Leprosy is found in all climates ; it is not 

 specially confined to the seashore, it occurs in regions where 

 fish diet cannot be resorted to, and where other articles of diet 

 such as pork and rice (to both of which have been ascribed a 

 causal agency in the production of this disease) are not used 

 at all. The only factor that is common to all forms of the 

 disease, and that is met with in every case, is the leprosy 

 bacillus, and in spite of the fact that we have not yet been 

 able to trace the method of contagion or infection through 

 the agency of this bacillus, we must, from what is known of 

 the presence and action of bacilli in other diseases, assign to 

 it the role of leprosy producer, until much stronger evidence 

 than we have yet obtained can be adduced in favour of any 

 other cause.
