The Rot in Sheep.

with much of their food even when they are young, contrasts 
greatly with the feeding and arrangement liad recourse to in the 
bringing up of cattle or sheep. Later on in life the uses to which 
horses are put likewise prevent to a great extent their reception 
of the penultimate forms of the fluke. Nevertheless, distomata 
have now and then been found in the horse and also in the ass, 
and they were so by Daubenton. The late Professor Sewell, of 
the Royal Veterinary College, likewise discovered some flukes in 
the ass, specimens of which are preserved in the College Museum. 
In addition to these examples, it may be mentioned that we were 
recently consulted by Mr. Pritchard, M.R.C.V.S., Wolverhamp- 
ton, respecting a case communicated to him of flukes in the liver 
of a horse. Elsewhere we have spoken of the susceptibility of 
the pig and also of the hare and rabbit to flukes ; so that the 
instances of simple-stomached animals being affected are not so 
unfrequent as might have been inferred from the formation and 
office of their digestive organs. 
In herbivora of such large size as the horse and ox, the ill 
effects of the entozoa are not so marked as in the sheep and 
smaller animals. Besides which, their number is generally 
limited, few existing as a rule. Dr. Budd has justly observed in 
his work ' On Diseases of the Liver^ 1857, that "the supposition 
that the distomata cause, in some way or other, a serous discharge 
from the gall-ducts they inhabit, accounts for their producing 
less effect on larger cattle than on sheep, hares, and rabbits. A 
loss of albumen that would exhaust these small animals would 
have little effect on an ox." 
According to Kiichenmeister, the entozoon has likewise been 
found in man by several persons, among whom he names Mal- 
pighi, Chabert, Biddloo, Pallas, Brera, Mehlis, and some others. 
In our own country similar cases of their existence are recorded 
by Mr. Busk, F.R.S., and Professor Partridge, of King's College. 
Mr. Busk took fourteen specimens of the variety called the Dis- 
toma crassum from the liver of a Lascar, one of which is preserved 
in the museum of the Royal College of Surgeons. The particulars 
of Mr. Partridge's case are narrated in Dr. Budd's work on the 
Liver, previously referred to. 
In addition to these cases, distomata have also been discovered 
under circumstances which, although very remarkable, are good 
evidences that the entozoon can be matured within the exter- 
nal tissues of warm-blooded animals, as in those of the cold- 
blooded. Thus it is recorded that Giesker, of Zurich, took one 
from the sole of the foot of a woman, the wife of an overseer 
of a silk-factory near to that town, which it is supposed had 
embedded itself in the skin as a cei'caria while she was engaged 
in " washing linen in the more stagnant parts of the Lake of
