sites had a tendency to somewhat modify the symptoms of 
rabies and render the cases apparently more complicated. 
The most prominent symptom presented in these two cases of 
rabies was clonic spasms, which seemed to be particularly 
severe in the muscular tissue about the abdomen. Perhaps 
this can be accounted for by the great number of parasites 
found in the colon and caecum. 
Cobbold, in his work on “ Entozoa of Man and Animals,” 
gives quite a detailed account of the different outbreaks caused 
by these parasites in Great Britain, as reported by differ¬ 
ent veterinarians, and as studied by himself. He describes 
one case in which the symptoms somewhat resemble those 
manifested in the cases I have described. Williams, in his 
“Treatise,” states that the animals which suffered from these 
parasites in an outbreak in 1874, were all rising two years old, 
and that older animals running with them remained well and 
free from the parasites. He also states that in his opinion, in 
conjunction with the ages of the affected animals, diarrhoea 
and emaciation may be considered as diagnostic symptoms. 
In the cases which I have described, diarrhoea was absent, 
the animals were in fair condition, and in case 3 the horse was 
nearly four years old. 
The intestines in which parasites were found presented a 
nearly similar appearance to the description given by Cobbold 
and Williams. The mucous membrane presented a great 
number of small brown or reddish spots which contained the 
parasites. Some of these spots contained two worms, and 
others only one, and they were either coiled in a round ring 
or in the shape of the letter s. The mucous membrane was in¬ 
flamed and thickened, and in it were a few pus deposits or 
small abscesses in which the pus was usually inspissated. 
Cases 2 and 3, as well as other animals on the farm, had de 
rived their drinking water sometimes from a well, at other 
times from an outlet of tiles that were put in the ground to 
drain a low part of the farm. 
After the death of the two animals 1 prescribed ol. terebinth, 
alternated with ferri sulph. and gentian, for other horses on 
the farm and all have done well. •
