the intestinal canal, &c. When thus located they often pro¬ 
duce ascites in young colts, and several such cases are recorded 
in the annals of veterinary medicine. Their adhesion to the 
viscera does not depend upon the peculiarly barbed arrange¬ 
ment of the integument near to their heads, as is the case 
with the jllariae found in the abomasum of lambs, but on the 
development of their sucking-discs.] 
POISONING OF A FILLY BY YEW. 
By J. E. Cornelius, M.R.C.V.S., Shefford, Biggleswade. 
I was requested yesterday evening, November 2d, to 
attend a brood mare and three yearlings, the property of 
Mr. Davis, a large agriculturist, residing near to Biggleswade, 
in consequence of a two-year old filly having been found dead 
in the field, in which she had been kept with the other animals, 
and the owner fearing that he might lose some of them from 
the same cause. On examination, I could not detect any¬ 
thing amiss with the animals, but I deemed it prudent, 
nevertheless, to administer a dose of physic to the brood 
mare. I waited for an hour and a half to see if any indi¬ 
cations of ill health would present themselves, but such was 
not the case. It being now night 1 returned home without 
further investigation, and on the next morning I went over 
again for the purpose of making a post-mortem examination. 
Previous to doing this I walked into the field where the 
animals were kept, thinking it possible that I might find a 
vegetable poison of some kind which might have been the 
cause of death. 
I had not much trouble in tracing the animals into an ad¬ 
joining shrubbery, the gate of which had been accidentally 
left open; and here their foot-marks were plainly visible around 
one of the shrubs, of which it was evident some had been 
eaten. It at once struck me that it was a variety of yew, 
although I was not sufficiently acquainted with these plants 
to decide the question forthwith, and I felt the inconvenience 
of being devoid of a knowledge of botany. By the bye I hope 
the day is not far distant when botany will be added to the 
curriculum of the veterinarv student’s studies. 
I subsequently proceeded to make a post-mortem examina¬ 
tion, when I found the stomach full of ingesta of a natural
