VALVULAR DISEASE OF THE HEART. 
subject of colic during the past year, but which required only 
ordinary measures to effect its removal. 
[We thank Mr. Markham for affording us the opportunity 
of examining this morbid specimen. It consisted of about 
two feet of intestine, continuous with the pelvic portion of the 
rectum. A rent, as described by Mr. Markham, existed in 
the mesentery, or as it is sometimes called, the meso-rectum, 
and into this a double fold of the intestine had passed and 
become strangulated. The laceration was evidently of very 
recent date. The gangrenous condition of the impacted 
intestine was of itself quite sufficient to cause death, and the 
nature of the lesion was such as fully to explain the symptoms 
exhibited by the animal. The rupture of the ileum, of which 
Mr. Markham speaks, although likewise recent, was probably 
connected with some long existing functional derangement of 
the organs of digestion and assimilation, and which led to the 
repeated attacks of colic. One of these attacks most likely 
preceded and became the cause of the lesions which were 
found in both the ileum and the meso-rectum.— -The parasites 
were ordinary examples of the entozoon, called the taenia 
serrata. These creatures are usually found in groups of ten 
or twelve in number, and often but in one part of the 
intestinal canal and that the caecum, firmly attached by their 
sucking discs to the mucous membrane. They rarely measure 
more than an inch in length, and whether they are fully 
developed creatures, perfect in themselves or immature forms 
of other taenia, remains as yet an undecided question.] 
VALVULAR DISEASE OF THE HEART. 
By Francis Blakeway, M.R.C.V.S., Stourbridge. 
On January 24th, 1855, I was requested by Mr. W. 
Hazledine to see a bay gelding, two years old, that 
had been unwell for some time. Upon my arrival at his 
farm, at 4 p.m., I found, somewhat to my surprise, that 
the animal was fast sinking. Fie was still standing, but his 
body was with much difficulty supported. The respiration 
was of that character commonly called “ panting,” and numbered 
from thirty-five to forty inspirations in a minute. The pulse 
at the jaw was regular but quick, being ninety per minute, and 
easily compressed. By auscultation, the sound of the heart
