bore into the skin of their host, and then develop in the subcu¬ 
taneous connective tissues. Then they act as foreign bodies, 
cause inflammation and supuration, and gradually pigeon-egg sized 
tumors, which eventually rupture. The larvae remain about nine 
months in the spaces, then leave them through the opening already 
formed, and complete their further development in the ground. 
Ochromyia ant/iropophaga , according to Raillet, cause a sim¬ 
ilar malady in the skin of dogs from the passage of larvae into 
thin skin, as does the oestrus bo vis in cattle. The nodules reach 
the size of a hazel-nut before they burst. They are most com¬ 
monly found on the tail, ears and paws. 
Lucilia serinata , (Jennes and Vaq Laer), which is probably 
identical with musca Caesar, causes a disease in Dutch sheep, 
which is known under the name of u de Vliegenziekte de Scha- 
pens,*’ and is caused by the fly in question depositing its ova un¬ 
der the skin in places where it is thin, and especially in the neigh¬ 
borhood of the rectum. The result is a sieve-like piercing, and 
more or less extensive undermining of the skin. 
Leptus autumnalis , (harvest mite) causes not only in man, 
but, (according to Defrance and Fiedberger) in the dog, a pustu¬ 
lar skin eruption. There appear on various portions of the body 
small red nodules, on which the mites are located. Later on, the 
nodules coalesce, and finally there are formed quarter-dollar sized 
irregular round areas, on which the skin is hairless, hypersemic 
and thickened.

SOME PECULIAR TERMINATIONS OF POST-PHARYNGEAL AB- 
CESSES IN SOLIPEDS. 
By L. C. Wakefield, D.Y.S. 
In view of giving the readers of the Review a chance for a 
more extensive prognosis in cases of post-pharyngeal abcesses with 
diseased guttural pouches, provided they are not called until the 
animal is in the last stages of the disease, as has been the case in 
my practice, I subjoin two cases that I have met with lately, as 
they differ from most cases that I have seen which have proved
