194 ON THE SO-CALLED CHIGNON FUNGUS. 
on Dr. Fox's mind that in the excitement he thought it was himself 
who discovered the vegetable growth, and that he has forgotten alto- 
gether what he has seen and said at the two meetings of the Patho- 
logical Society. v 
Dr. Fox's paper, " The Chignon Fungus," is, in its greater part, a 
reproduction of what has been said by Lindemann and a daily Ham- 
burg paper, while a comparatively small portion contains some mi- 
croscopic researches illustrated by thirteen woodcuts. This portion 
is a most unfortunate one, for Dr. Fox not only drew everything 
that came within the reach of his objective, but described it also as a 
stage of development of the Fungus. Thus we find four or five 
different Alga, and three Ltfuoria (Psorocentrum micans, Monet 
termo, and Actynophrys Sol). In fact, amongst the twenty odd ob- 
jects of the paper I find only six belonging to the plant in ques- 
tion, while all the rest were admixtures of the saccharine solution 
in which the growth of the plant took place. But even the former few 
are incorrectly drawn or misinterpreted. Fig. 75, for instance, is y 
no means the knob on the hair as seen under the microscope, but it 
represents rather one already damaged by pressure. The appearance 
of the knob is perfectly regular, and— as may be seen even with the 
naked eye— bulbiform.' Fig. 78 is not a large cell, " undergoing divi- 
sion very actively," but a number of cells imbedded in their original 
stratum. Had Dr. Fox been less anxious to address the public, and 
studied more the division, development, and growth of the cells, he 
would doubtless not have fallen into such error.

Fig. 1. The contents of a knob just taken from the hair and viewed by t ie 
microscope, principally consisting of sporules of Pleurococcus Ben/e i, 
containing two or four, exceptionally three large nuclei, remnants ol nay 
and protoplasma. 2. Another knob, after vegetating fci nty-four hours in a 
saccharine solution, the nuclei converted into small, highly refractory ^ 
some cells (a a) broken and the nuclei escaped therefrom, others (b b b) eing 
much inflated, others again (c) having differently-shaped projections. 3- ^

visible, and representing different stages of intermediate development, 
there appear again the original sporules containing their large nuclei. '
