 Tommasi-Crudeli was announced, constitutes nega- 

 tive evidence of a much stronger character. The 

 Bacillus malar ice, according to all accounts, should 

 be much easier to recognize than Koch's bacillus of 

 tuberculosis, which has already been seen by numer- 

 ous physicians in nearly every large city in this 

 country and in Europe. But who on this side of 

 the Atlantic has seen the Bacillus inalamc? Yet
