No. 15. Kirby and Spence. Introduction to Entomology, 1, 239. 
(Peoples edit., p. 74.) <A larva belonging to the Diptera, perhaps to 
the Tipulide, with which however it do's not so entirely agree as to 
take away all doubt, was passed by a person (sex not given) in 
Ipswich with the urine. It was alive and extremely active. The 
larva is carefully described. 
- No. 16. Jer. Van Rensselaer, M.D. Silliman’s Journ., 1828, 
xu, 229. On a larva liberated with urine. The larva was dis- 
charged by a girl, and is, according to the short description, a 
coleopterous larva, probably that of Tenebrio molitor. 
Rev. L. Jenyns. Trans. Entom. Soc., Lond., 1839, 11, 152, pl. xv, f. 
1-8. Notice of a case in which the larvae of a dipterous insect, 
supposed to be Anthomyia canicularis, were expelled in large quan- 
tities from the human intestines. The larvae, according to the figure 
and the description, belong probably to Homalomyia scalaris, and were 
discharged by an old clergyman in enormous numbers from the 
bowels. One passage in the paper induced me to suppose that some- 
times the larvae were also discharged through the urethra, and for 
this reason the paper is quoted. However the fact is not stated in an 
unquestionable manner. 
No. 17. Dr. Erismann. London Medical Gazette, 1837, xx, 
846, (recorded after Schmidt’s Jahrb. du Med. and Schweizer, 
Zeitsch., 1, 1.) A robust young man was attacked suddenly by 
symptoms of the most acute inflammation of the bladder. After 
suffering intensely for five days, he found himself unable to pass his 
water, and this evidently from some mechanical obstruction in the 
urethra. Before a catheter could be introduced, he discharged a 
body of the size of a pea covered by purulent matter, which was 
found to contain a little beetle, Ptinus fur, which died directly on the 
exposure to the atmosphere. 
The communication resembles those previously quoted from 
Gahrliep, and the final passage endangers even more the trustworth- 
iness of the case. 
No. 18. Dr. Schrader in Rust’s Magaz., 1824, x1x, 487 and 
1826, xxI, 26, describes the larva of a fly discharged with the urine 
as asnail. J have not seen the paper, which is related and corrected 
in Siebold’s article on Pseudoparasites.
