Faiinia caniciilaris etc. 
expulsion of the larvae was followed by a regaining of the appetite 
and sleep. In 1876 Judd described the discharge of the larvae of 
F. scalaris from the intestine of a boy in Kentucky, U.S.A. 
Thebault (1901) records the occurrence of dipterous larvae in the 
intestine with the production of haemorrhage, as is sometimes the 
case. 
Stephens (1905) records the larvae of F. scalaris as having been 
passed per rectum. Cattle (1906) refers to a case in which large 
quantities of the bot-fly occurred in the intestine, there were few 
symptoms and the larvae were being discharged per anum seven months 
after he first saw the patient. The writer (1909) has also recorded the 
occurrence of F. canicularis in the stools. Kecently, Soltau (1910) has 
recorded the occurrence at Plymouth on the 28th of May of the larva 
of F. canicular'is in the stools of a man who had not previously had 
intestinal pains. The occurrence in September, 1909, in the faeces 
of a boy aged 12, of the larvae of a species of Fannia has been 
described by Garrood (1910). 
Occurrence in the Urinary Tract. 
It would appear most unlikely for the larvae of these insects to be 
discharged from the urinary tract and yet there are a number of records 
of such occurrences. These have been excellently summarised by 
Chevril (1909), who found twenty cases of myiasis of the urinary tract 
recorded in literature. Six of these may be considered authentic, ten 
as very probable or probable, and four doubtful. 
Tulpius (1672) records the passage of 21 small larvae from the 
lu'ethra. From the figure which is given it would appear that these 
are F. canicularis. In 1792 Veau de Launy recorded the occurrence of 
and figured a larva which resembles F. canicularis. This larva was 
o 
expelled with the urine by a man of 45. Hagen (1879) gives a 
summary of the literature up to that date in which twenty cases of 
insects of various orders are recorded as being expelled with the urine. 
Eleven of these insects were Diptera. Lallier (1897) gives eleven cases 
of insects expelled from the urinary tract; three of these cases were not 
recorded by Hagen. Chevril {1. c.), in addition to a critical examination 
of the previous records, as already mentioned, gives an additional case 
of the occurrence of the larva of F. canicularis in a woman of 55 who 
suffered from albuminuria and urinated with much difficulty. On 
May 26th, thirty to forty larvae of F. canicularis of different sizes were 
passed.
