Stimulation oFSterigmatocystis by chloroform 



Marion Elizabeth Latham 



* 



The response of fungi to the influence of salts and other chem- 

 ical compounds, as manifested by accelerated growth, increased 

 weight, and active evolution of carbon dioxide, has been the sub- 

 ject of several investigations within a recent period. Raulin's * 

 early observations have been much extended by Richards f who 

 has ascribed! the action to a more economical use of the nutri- 

 tion at hand, that is, he has proved the economic coefficient of 

 Kunstmann § to decrease as the stimulant approaches its point 

 of optimum efficacy, Ono, |j Yashuda,^ Hattori, ** Stevens,!! 

 Iwanoff,!! Benecke§§ and others have extended the range of
