and isolated spores in the earlier stage* in the growth of 

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

 morphological characteristics as established by me agere 

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



One of the obje(;ts of my investigations was to estab- 

 lish a possible polymorphism in the life of. this fungus 

 which was suggested by tlie two different names "Euro- 

 tium Oryzse" and "Aspergillus Oryzie" under which the 

 fungus went at the time. 



Further observations published by me in the "Original 

 Communications of Zymotechnic Institute" Vol. 2, page 

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

 taining plain preparations of the fully grown fungus, 

 showing the Sporangia completely developed in every re- 

 spect justify the appelation of "Aspergillus." 



This is readily apparent from figure 2 taken from my 

 later publication and which I think will be of additional 

 interest as it completes the morphological biology of this 

 fungus, which (although the industrial expectations at- 

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

 zed) will always be a subject of great scientific interest, 

 not only to the mycologist and microscopist but to the 

 physiologist 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
