234 Barker.—A Fragrant ‘ My coder ma' Yeast , 
vulose, maltose, and saccharose ; the fermentations, except in 
the case of laevulose, were very vigorous. Their genus Endo - 
blastoderma was based on the property of endogenous cell- 
formation by its members, and they claimed that this manner 
of formation had been observed by them in the case of the 
organism just described. 
Briefly stated, the method of endogenous cell-formation 
was as follows:—in a young cell a refractive particle made 
its appearance, and increasing in size made its way bodily 
through the cell-wall: it then developed in exactly the same 
manner as a bud produced in the ordinary manner by con¬ 
striction from the mother-cell. The authors pointed out the 
great similarity of their organism to Hansen’s Saccharomyces 
anomalus , and laid stress on the fact that the exact relationship 
could only be determined by testing the power of the latter 
to form cells endogenously in the manner just described. 
Klocker ( 6 ) undertook this work, and failed to discover in 
S. anomalus any trace of endogenous cell-formation apart from 
the ordinary spore-formation. He noticed, however, the 
appearances on which Fischer and Brebeck based their view 
that endogenous cell-formation took place, and found that they 
were due to ordinary budding, the buds in some cells being 
produced in a direction more or less vertical to the cover- 
slip. On growing, these buds shifted their petition in such 
a way that they appeared to move from the inside of the 
mother-cell to its exterior. Similar results were also obtained 
by him, when a variety of Mycoderma was investigated. 
There appears thus to be no ground for Fischer and Brebeck’s 
construction of the new genus, Endoblastoderma. Klocker 
stated in his paper that there could be no doubt that 
5 . anomalus and E. pulverulentum are identical, from the 
description given of the latter. 
Nielson ( 7 ) has investigated the effects of temperature on 
spore-production by S', anomalus. At temperatures above 
33° C. no spores were formed. At 30°C. they made their 
first appearance in seventeen to nineteen hours ; at 28° C. in 
seventeen and a half to nineteen hours; and at 25° C. in
