TABLE 10. 

 DISINFECTANT ACTION OF HYDROCHLORIC ACID ON B. coli IN i PER CENT PEPTONE SOLUTION. 



TABLE ii. 

 DISINFECTANT ACTION OF SULPHURIC Aero ON B. coli IN i PER CENT PEPTONE SOLUTION. 



TABLE 12. 



DISINFECTANT ACTION OF HYDROCHLORIC ACID ON B. typhi IN i PER CENT PEPTONE SOLUTION. 



In these tables the dissociation values given are those determined 

 for distilled water, and not those which actually obtain in a peptone 

 solution. The amount of dissociated hydrogen required for disin- 

 fection, when estimated in this way, is seen to be nearly 10 times as 

 great as in tap water. For comparison the results are brought 

 together in Table 14.
