DECEMBER 28TH. 
MICROSCOPICAL MEETING.—ANIMAL PARASITES 
—EPIZOA. 
Mr. Wonror remarked that since their last meeting, when it was 
determined to have ‘‘ Epizoa” as the evening’s subject, he had put him- 
self in communication with several friends who could help in supplying 
objects, and he was happy to say Dr. Ormerod had lent a series of 
parasites from his cabinet, among which he might mention the mole 
flea as a notable one ; Mr. T. Curties, of Holborn, had very kindly 
sent, from his cabinet, a very choice collection of specimens, among 
which were the new elephant parasite, chigoes, a series of ticks, and 
picked specimens of parasites from man and other animals, as well as 
human and other acari; Mr. Hennah had brought a collection of bird 
parasites, &c. ; Mr. Sewell and he had also a number of objects. He 
would, therefore, suggest that they should take the specimens in order, 
by which means the greatest number could be seen by those present, 
if the objects were simultaneously changed. 
The suggestion being approved of, the meeting became a con- 
versazione, when Messrs. Hennah, Glaisyer, R. Glaisyer, Marshall 
Hall, Sewell, Turner, and Wonfor exhibited the various objects. The 
first shown were ‘‘ fleas,” which included the common flea, and those 
from the cat, dog, mouse, squirrel, bat, hare, mole, chicken, the 
chigoe, or jigger,—the female of which inserted herself under the toe- | 
nails, and then increased in size until she was as large as a pea, when 
she deposited her eggs,— and larvee and eggs of fleas. 
‘‘ Ticks” were then put under examination, and here a variety 
was seen from sheep, dog, ox, red-deer, hare, tortoise, ferret, and 
elephant, the last named, which was new to science, having quite 
a long proboscis. 
Then followed acari from pig, horse, camel, bat, swift, water-rat 
(remarkably like their host in form), mole, a very curious fellow, and 
man. The last named produces that intolerable irritation, associated 
with a Scotch musical instrument. To these succeeded “ lice” from 
man,—three forms, head, clothes, and crab lice,—mouse, pig, calf, 
dog, horse, spider-monkey, roach, canary, bee, &c. Next in order 
came bird parasites, the most notable among which were those from the 
swift, pigeon, moorhen, Australian crane, white goshawk, &c., and
