and isolated spores in the earlier stages in the growth of 

 fungus, taken from that article. It will be noticed that the 

 morphological characteristics as established by me agere 

 with these found by Mr. Grolden in the main features. 



One o the objects of my investigations was to estab- 

 lish a possible polymorphism in the life of this fungus 

 which wis suggested by the two different names "Euro- 

 tium Orzae" and "Aspergillus Oryzae" under which the 

 fungus vent at the time. 



Furt.er observations published by me in the "Original 

 Commnications of Zymotechnic Institute" Vol. 2, page 

 65 (isfie of October 18, 1892) in which I succeeded in ob- 

 tainin; plain preparations of the fully grown fungus, 

 showig the Sporangia completely developed in every re- 

 spectustify the appelation of "Aspergillus." 



Th* is readily apparent from figure 2 taken from my 

 lateipublication and which I think will be of additional 

 inteist as it completes the morphological biology of this 

 funus, which (although the industrial expectations at- 

 taced to the same at one time may not have been reali- 

 zec will always be a subject of great scientific interest, 

 ru only to the mycologist and microscopist but to the 

 p^siologist and chemist as well.

Nuclear Phenomena in Smuts. — Harper (Trans. Wis. 

 Acad. Sci. Arts & Lett. 12 : 475-498 separate) finds that 

 the nuclear phenomena in germinating Ustilago scabiosa 

 are as follows : The promycelium pushes out without nu- 

 clear divisions having taken place in the spore. The nu- 

 cleus wanders out of the spore and is to be found in the 

 promycelium when it has reached one-thirdof the mature 

 length. When the promycelium is mature the nucleus 

 lies near its middle. When Flemming's triple stain is
