The six turbid broth tubes, indicated above as selected for further 

 examination by gelatine plate culture, yielded the following results :-- 



Broth tube. 



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

 Flask 1 Incubator. (Typhoid Absent.) 



The colonies yielded pink growths on potatoes and liquefied 

 gelatine ; they were therefore not those of typhoid. 



(79.) Typhoid-infected Unsterilised Thames + O'l per cent. Nad, 

 Flask 1 Refrigerator. (Typhoid Absent.) 



The colonies presented some resemblance to typhoid, as did 

 also the growths on potatoes obtained from them. No indol 

 reaction. On inoculating into gelatine tubes, the latter were 

 found to very slowly liquefy on long keeping. On inoculating
