STANDARDIZATION OF DISINFECTANTS 

 TABLE V 



Valuable information regarding the comparative toxicity of 

 many substances used as disinfectants may be obtained from 

 study of the comparative medicinal doses. For example, the 

 medicinal doses of phenol, betol, resorcinol and corrosive sub- 

 limate are i grain, 3 grains, 4 grains and J^o grain respectively. 

 These doses are practically in proportion to the toxicity of the 

 substances named and stating the dosage in the terms of the 

 phenol toxicity coefficient as proposed by Hale, we would get the 

 'ollowing results: 



Phenol 



Betol 



Resorcinol 



Corrosive sub. . .
