Report on the Bacteriology of Water. 

 Examination by Phenol Broth-culture, 21.6.1893. 



445 



Thus, on this occasion, all the waters reacted in forty-eight hours 

 with the phenol broth-solution. The following results were obtained 

 on plate cultivating the turbid broth tubes : 



Broth tube. 



(88.) Typhoid-infected Unsterilised Thames + O'l per cent. NaCl, 

 Flask 1 Incubator. (Typhoid Absent.) 



The colonies on transference to potatoes yielded light brown 

 growths, which were certainly not due to typhoid. 



(91.) Typhoid-infected Unsterilised Thames + O'l per cent. NaCl, 

 Flask 1 Refrigerator. (Typhoid Absent.) 



The potato growths from colonies somewhat resembled 

 typhoid ; there was also no indol reaction, but gelatine tubes 

 were slowly liquefied by the organism, which was, therefore, 

 not typhoid. (See similar experiences with No. 79, p. 443.) 



(89.) Typhoid-infected Unsterilised Thames + 1 per cent. NaCI, 

 Flask 1 Incubator. (Typhoid Absent.) 



The potato growths from colonies were thick and brown in 

 colour, quite unlike those of typhoid.
