life of their presence, and the celebrated rabbit of Dr. Thudichum had 
flourished on trichinows muscle, though, after death, every part of the 
voluntary muscle, except the heart, was full of them. 
As regarded the epizoa, their cabinet contained some very choice 
slides, among them the chigoe flea, or Pulex infestans, 
He had, very fortunately, been able to verify the life history of 
the common flea. Mr. R. Glaisyer had obtained for him some fleas, 
and sent them to him in a bottle. On the sides of the bottle he 
noticed some white bodies, which, on examination, proved to be eggs. 
Keeping the bottle in his waistcoat pocket, at the end of a few days 
he saw some larve had hatched out. Some of these he exhibited at 
one of their meetings alive. After a time some of them formed 
cocoons, from which eventually came fleas, one of which he had 
mounted. As far as he could recollect, the time from the eggs to the 
perfect insects was about 25 days. 
In answer to a question, Mr. Wonror stated that at different 
times he had examined pork, ham; and bacon purchased in Brighton, 
and had never found trichinz present, though some Hambro bacon 
given him by a friend in London, was so full, that many cists con- 
tained two or three individuals.) He might say one ounce of the 
muscle contained thousands. Had any of this been eaten without 
proper cooking, to kill the entozoa, they would have become sexually 
mature in the stomach, and deposited their eggs, the young trichinze 
from which would have commenced boring through the intestines to 
the muscular system. It was at this boring stage that they were so 
dangerous. 
The meeting then became a Conversazione, when some very 
beautiful specimens were exhibited of ascarides, tape worm, hydatids, 
eysticerci, strongylus, and muscle from the pig, rabbit, and man, 
infested with trichina spiralis, by Messrs. Sewell, Hennah, Glaisyer, 
and Wonfor.
