epithelium surrounds the broken hair about one fourth of its 
length. 
Case 11. — Alopecia circumscripta. My celia filaments and 
spores projecting ruggedly from the edges of dirty brown 
hair; filamentous masses very fine, drying up, and spores 
also ; a peculiar branch of mycelium, with lance-like termi- 
nation, from one of the hairs. 
So that in eight cases there was most decided evidence of 
fungoid growth, finding in them filaments and spores. In 
three cases, one of which was the product of syphilis, no 
fungoid growth was found. The hair from the margin of 
the bald spots was taken for examination in most instances. 
PoRRiGO SCUTULATA (Trichophyton tonsurans). Syn. Tinea 
tonsurans. Herpes tonsurans, Ringworm of the scalp. 
Case 1 . — Ringworm taken at school. Character : patches 
of the scalp covered with minute vesicles, the discharge from 
which had dried into thin crusts; hair on these patches 
thin, light, and friable, and very scanty, being broken off 
short, and standing out abruptly from the skin. A fine 
fungoid growth was visible, the mycelia and filaments branch- 
ing off very beautifully ] a hair was seen covered with black- 
ish fungi ; epithelial scales abundant (fig. 3) . 
Case 2. — Ringworm. This child was sister to the above, 
and her scalp presented similar appearances. Epithelium 
thickened and running along the hair like a pyramid; ves- 
tiges of vegetative growth. 
Case 3. — Ringworm. Filaments and spores over hairs, 
with peculiar bulbous protuberances. 
Case 4. — Ringworm. Fungi shooting from the root of the 
hair; epithelial scales with filaments. 
Case 5. — Ringworm. A remarkable twisting and diseased 
condition of the hairs, with numerous ovoid spores, but no 
filamentous growth seen. 
Case 6. — Ringworm. Hairs matted together, and project- 
ing from them mycelia filaments, and sporules separated 
and distributed; a chain of sporules projecting from a hair, 
as seen in cases of Plica polonica given by Kiichenmeister. 
Case 7. — Ringworm after dropsy. Hypertrophied epithe- 
lial scales glued together ; the bulbous portion of the hair is 
also covered with adherent scales, upon which mycelia fila- 
ments and sporules are freely distributed ; chains of sporules 
as in former (fig. 4) . 
Case 8. — Ringworm. Branched fungoid filaments and a 
few sporules visible.
