ditional remarks proposes that the name Scholechiasis used by Kirby 
and Spence for all diseases occasioned by the larvae of insects, should 
be retained only for those arising from Lepidopterous larvae. The 
disease by coleopterous larvae he calls Canthariasis, and those by 
dipterous larvae, Myasis. On pl. x x11, f. 2-5, are represented various 
larvae from the human body contained in the musem of the College 
of Surgeons; fig. 2 is a worm, or at least no insect, f. 3, 4 are larvae 
of Homalomyia, f. 5 is Oestrus hominis. 
The paper is important as the only list in existence and quotes 108 
cases; seven of which belong to the urinary passages. The quotations 
in the paper are rather lax and not over correct. Dr. Koch in 
Ammon’s Monatsschrift f Medicin., 1838, 1, 542, has given also a 
list of the larvee observed in the intestines of men. 
No. 19. R. Owen. Trans. Ent. Soc., Lond., 1840. Proc. p. 7, 
April 6. Report of a dipterous larva, distinct from Anthomyia and 
wanting the lateral filaments, several of which had been discharged 
from the urinary bladder of a patient. 
Th. v. Siebold, in R. Wagner, Handworterbuch d. Physiologie, 
1844, 11, 683, gives in his excellent article, Parasites, a chapter 
on Pseudoparasites. He speaks at some length on insects discharged 
from the bladder, and is strongly inclined to disbelieve the trust- 
worthiness of the published cases. Prof. v. Siebold remarks, p. 688, 
that he possesses alarva of Clerus formicarius, communicated to him 
as an urine-worm, but it doubtless fell in the vessel by some chance. 
No. 20. Dr. Cutler of Watertown, Mass. A larva of Homa- 
lomyia discharged with the urine by a country boy. 
I by no means pretend that the list of authors enumerated by me 
presents a full record of all published cases, but I have gone 
through a large number of books and periodicals without finding 
more. Nevertheless a careful perusal of medical journals will doubt- 
less furnish other published cases. 
In four of the twenty recorded cases I was unable to examine the 
works myself. The value and trustworthiness of all the cases are very 
far from being equal. The two with Oniscus (Turner and String- 
ham) and the one with Eristalis (Brera), the case by Lochner of 
which nothing is known should be at once discarded. But even of
