The colonies presented some resemlblance to typhoid, so they 

 were further examined by potato growth, indol, gas-bubble, 

 and milk tests, in all of which the resemblance was maintained.

 the difference was not sufficient to place the matter beyond 

 doubt. They were finally proved not to be typhoid by keeping 

 the gelatine tube cultures for some time, when both the surface 

 and depth growths were found to be distinctly yellow in colour. 

 I have repeatedly encountered this same organism, which 

 might be mistaken for typhoid in its earlier appearance in 

 plate cultures, but it must clearly be understood that the 

 resemblance is only a superficial one, and it was only sub- 

 mitted to so many tests because in these examinations anything 

 bearing the slightest resemblance to typhoid was remanded 

 for further enquiries. 



These saline waters were again examined by phenol broth-culture 

 on 13.6.1893, with the following results :
