external meatus^ and had been treated both locally and 
generally with a variety of medicaments. 
The diifferences between the description given by Robin 
and that which I have to offer are such as to lead to the 
belief that the objects are not similar. 
1st. 1 detected no cysts^ but flocculent membranous-look- 
ing masses. 
2d. He describes the stipe as long^ and containing within 
it small granules (or having a granular interior). Now 
although the accompanying has a rather long stipe,, it does 
not contain spherules or granules. 
3d. The pileus is said by Robin to be small and of a 
greenish colour^ whereas that here shown is comparatively 
large and of a reddish-brown colour. 
4th. The position and character of the spores are distinctly 
different. Robin speaks of them as granules, single or 
double, spread over the surface of the upper swollen extre- 
mity of the stipe ; but those here exhibited are closely 
packed oval spores, completely enveloping the upper extremity 
of the stipe, forming a compact pileus. 
Further, there is a difference in the cases furnishing the 
growth, the contrast between a scrofulous child, eight years 
of age, and a healthy man in the prime of life, is as great as 
could be, and tends to show that the scrofulous habit has no 
special influence in favouring the growth of the parasite.
