cover the places deprived of hair consist of the parasite mixed 
with a certain quantity of epithelial scales. 
Case 1. — The hair near the bulb. Mycelia and filaments 
running along its surface^ as in PI. IV, fig. 1. 
Case 2. — Baldness of portions of the scalp and whiskers. 
Parts examined_, hair-bulbs and crust from the cheek. Fun- 
goid filaments with masses of epithelial scales ; portions of 
hairs were covered with filaments lying on the epithelial 
masses. 
Case 3. — Circumscribed Alopecia of the scalp. Hair with 
mycelia growing and protruding from the sides, the hair 
itself filled with a blackish-brown colouring matter. 
Case 4. — Alopecia of nearly the whole scalp. The few 
straggling hairs which were pulled off the scalp presented no 
bulb, but were distorted and broken stumpily ; tufts of spores 
were grouped on the external surface of the hair. 
Case 5. — Complete Alopecia of the scalp, eyebrows, and 
eyelashes, except a few straggling hairs on the scalp. Bulb 
and hairs entirely deficient of their animal matter, the whole 
depolarizing light; sporules and broken filaments scattered 
about (fig. 2). 
Case 6. — Circumscribed bald patches on occiput and be- 
hind the ears. Hair-bulb rugged, and hair uneven and 
devoid of central medullary matter ; striae and all marking 
on the surface obliterated and covered with spores and fila- 
ments. 
Case 7. — Alopecia circumscripta. Bald patches on the 
scalp, the remaining hair growing in profusion. 
First examination. — Bulb rugged and covered with a fila- 
mentous growth standing out with a dark, well-defined 
outline ; central pulp absent, and transverse markings oblite- 
rated. 
Second examination (after three months^ constitutional 
treatment). — Appearance improved; strise distinctly seen, 
and medullary matter or pulp in a great measure restored ; 
no filaments or spores visible. 
Case 8. — Alopecia circumscripta. Three bald patches; 
hair generally long and profuse ; bulb broken and rugged ; 
no vegetative growth visible. 
Case 9. — Alopecia syphilitica. Hair with a peculiar 
socket-like insertion; and there is seen projecting from the 
root and running upwards, a casing of very transparent epi- 
thelium ; this is divided into two portions a short distance 
from the root. 
Case 10. — Mr. M — . Bald spots with gray patches. Hairs 
bent and deprived of their medullary matter ; a sheathing of
