The spores from the first ten cultures were transferred to 

 pure sugar cane extract, March 23, but no growth resulted. 



Potassium Hydrate. 



Kept to January 4 ; no further development. 

 Sodium Hydrate. 



Kept to February 8 ; no further development. 



The last two experiments agree in showing that the growth 

 of Thielaviopsis is inhibited directly the solution becomes dis- 

 tinctly alkaUne.
