On the Effect of Alkaloids upon Some Moulds. 



{Preliminary Note.) 



By 

 Atsushi Yasuda, BigalmshL 



For the parallel-investigation of the fungi 1 ), upon which I have studied 

 the influence of some inorganic salts, I have also tried, according to the 

 suggestion of Professor Miyoshi, the action of some alkaloids on the same 

 fungi. The fungi worked on are Aspergillus niger, Penicillium glaucum, 

 Mucw stolonifer, and Botrytis cinerea. As to the alkaloids, since most of 

 free bases are difficult to dissolve I have used chiefly the hydrochloric salts, 

 which I took the caution of drying before experimenting with them. The 

 alkaloids used are the hydrochlorides of morphine, strychnine, quinine, 

 cocaine, cinchonine, codeine, and sulphate of vera trine.
