to the genus Protomyces of De Bary,*? but now he transfers 
it to the genus Schinzia founded by Negeli*? on a fungus 
which causes galls on the roots of Cyperus, and calls it 
Schinzia leguminosarum, thus considering it to be closely 
related to the fungus in galls on the roots of Alnus first de 
scribed by Woronin.** It is quite important in view of 
Frank’s change of opinion at a subsequent date to note that 
an examination of the illustrations and descriptions which 
accompany this paper leaves no doubt that at that time he 
considered the bacteria-like bodies to be budded off from the 
hyphz though he did not actually see the budding take place 
This paper of Frank’s brought out a rejoinder from Kny** who — 
states that the bacteria-like bodies are the spores of the 
plasmodium. a 
The general effect of these investigations was to give# 
feeling of confidence in the view that the etiology of the tuber 2 
cles was primarily due to the irritating or stimulating influence 
of some organism in the soil, though there was great diver- q 
sity of opinion as to the character of the organism. : 
This feeling of confidence, however was soon shaken by the 4 
appearance in 1885 of a paper by Brunchorst.*® Bruncho® — 
He affirms the older views that they are normal ae aq

He believes them to be differentiated portions of the p! 
protein contents of the cells. While they possess 
bacteria they are inert and serve as receptacles 
of proteid substance by the plant since they were ? 
exceedingly rich in protein matter and that later oS hological g 
are absorbed by the plant. Because of their mo 0 eroids 
resemblance to bacteria Brunchorst termed them ee 
He observed the fungus hyphe but did not conse none 
stand in causal relation to the tubercles since he fou
