Thirteen cases were examined, in seven of which filaments 
and spores were clearly discernible, in the others epithelial 
scales only were found. These filaments and sporules were 
in no respect distinguishable from those found in the various 
diseases already described, and to which they have been said 
to be peculiar. 
Lepra, 
Case 1. — Epithelial scales, surrounded by a growth some- 
what doubtful. 
Case 2. — Epithelial scales only. 
Case 3. — Brownish-red ovoid clusters of sporules, with a 
filamentous growth, jointed, and epithelial scales. 
Case 4. — Ovoid spores, jointed filaments, and a beautiful 
mass of granular matter with numerous sporules. 
Case 5. — Mycelia filaments, jointed, with sporules. Epi- 
thelial scales (fig. 8) . 
Case 6. — Masses of filamentous matter and detached epi- 
thelial scales. 
Case 7. — Mycelia filaments and sporules, with epithelial 
scales. 
In seven specimens examined I found mycelia filaments, 
and spores in five of them, and in two epithelial scales only. 
These fungoid vegetations were very similar to those found 
in Psoriasis, no doubt identical with it. 
Ichthyosis. 
Case 1. — The disease in this case was a congenital hyper- 
trophy of the epidermis without any other indication of 
disease. The appearances presented under the microscope 
were large epithelial scales, massed and blended without a 
marked separation, the whole intermingled with filaments ; 
showing that a congenital disease or malformation may, 
under certain conditions, prepare a soil for fungoid growth. 
Ltchen. 
Case 1. — Neck and scalp. Disintegrated epithelial scales, 
mycelia filaments and sporules, reddish-brown, covering the 
hair (fig. 10). 
Case 2. — Scales only. 
Case 3. — Epithelium in abundance, with mycelia with a 
few spores. 
Case 4. — Filaments with spores, and epithelial scales. 
So that, in three cases out of the four examined, evidences
