occasionally found in the Human 13ody. 
opinions held by different individuals, I openly assert the fact 
that insects, independently of Entozoa, do occasionally exist in 
the human body, in most cases being found in the larva state, 
but in some cases in the imago state, and 1 trust that the 
Tables placed before the meeting will most fully bear out that 
assertion. 
The Tables are divided into thirteen Columns, and on the differ- 
ent divisions some few observations will be given. I hope, however 
imperfect they may appear, that others may be incited to add to 
them the result of their inquiries, and by an accumulated mass of 
evidence insure the attention of the medical profession, and thus 
assist its members in applying their science and skill to the miti- 
gation and cure of some of the most afflicting diseases incident to 
human life. 
The First Column presents those genera of insects which have 
been found in the body, amounting in number to twenty-three ; 
and it may be here remarked that perfect insects have as yet only 
been observed belonging to one order, namely, the C'olcoptera. 
They are the following genera : Flaps, Tenebrio, Staphylinus, and 
Dermestes. 
The Second Column relates to larvae which have been accurately 
ascertained, and I regret to state in several instances that various 
others have not yet been identified, or the number of cases produced 
on the present occasion would have been much more numerous. 
We have reason to think, from the rapid progress Entomology 
is making in Europe, that this will not long be a subject of com- 
plaint. 
Third Column. — This division gives the numerous authorities 
for the different cases which have occurred. Among them we 
shall find persons of various countries, of all ranks and profes- 
sions. Some instances are recorded by physicians and surgeons, 
many others by naturalists, and amongst the latter may be re- 
corded the celebrated names of Linnaeus, Olivier, Paykull, Ru- 
dolphi, Humboldt, Say, Germar, Spence and Kirby. 
The Fourth Column relates to the countries where the occur- 
rences took place, and we shall find in the New World, as well as 
the Old, the same general parasitic laws of nature. It is pro- 
bable that some countries are liable to peculiar insectal diseases, 
but the cases relating to Great Britain and Ireland form, in my 
humble judgment, a body of evidence in proof of the occasional 
existence of these parasites in the human body which is quite 
irresistible. 
The Fifth and Sixth Columns. — These two divisions give a re-
