Kg. 83 represents the appearance of the fungus 

 at the end of fourteen days, seen with an A -inch 

 object-glass. 



Fig. 63. 



Eig. 84 is a portion of the mycelium, taken from 

 the part over the hair, more highly magnified with 

 a ytt object-glass. 



Fig. 84. 



The ends of the filaments seen in fig. 85 are 

 analogous, in fact identical with those forms which 

 I have figured in my work on parasitic diseases of 

 the skin as resulting from the growth of oidium. 

 The globose head containing spores, is an early 



stage of that represented in fig. 86. The double 

 cell figured on the left was of a green colour like 

 many others. 



Fig. 85. 



Accompanying these appearances were, as in the 

 former case, cells — filled with smaller cells and

granules in active motion — furnished with] cilia, and 

 bodies undergoing the "amoeboid" transformation, 

 as seen in figs. 87 and SS, with y%-inch Powell and 

 Lealand.

Here, agaiu, we have the growth taking on an 

 algal phase in one direction, and fructifying into a 

 perfect fungus on the other hand. The drawings 

 I have given were made on the spot from the 

 microscopic objects, and I must do the artist 

 credit to say he has most faithfully and cleverly por- 

 trayed the actual appearances presented by the para- 

 site. The observations now recorded are in complete 

 harmony with those of Dr. Braxton Hicks on the 

 Volvox, and De Bary in his work published in 

 ]864, at Leipsic, "Die Mycetozoen, Ein Beitrag zur 

 Kentnniss Der Neidersten Organismen," and are 

 completely confirmatory of the opinion before a 

 vanced by myself, that the fungi found upon or 

 within man belong to one genus, and undergo an 

 infinity of variations under different circumstances. 

 In the present case the fungus approaches to the
