drenches, all these abated considerably, and she was considered 
to get perfectly well again. 
Within six weeks afterwards the animal again cestrated, and 
was put to the same bull, that was then serving in the district ; 
but, after having been served, the symptoms of oestration still con- 
tinued, and she was again put to him. This was repeated for 
four times, and without any effect in diminishing the tendency to 
bulling ; and, the vaginal discharge having become increased and 
somewhat bloody in nature, it was thought that the cow would not 
hold, and further attempts were declined. A veterinary surgeon 
was called in, and examined the sheath and penis of the bull, but 
found no diseased condition there ; and, having looked at the outer 
parts of the cow, saw no appearance of her having been bull-burnt, 
and therefore concluded her entirely amiss, and advised her imme- 
diate sale. The owner, however, did not do so, but determined to 
keep her on, and, consequently, put her out to grass at his earliest 
convenience ; and it will be seen in the sequel, that, had the real 
disease been fully investigated, the animal might have been cured, 
and made, in a short time, as valuable as ever. 
During all this time there still existed the muco-purulent dis- 
charge from the vagina; and, as was stated, after the repeated 
embraces of the bull it had become bloody, and still continued to 
be so. These symptoms, however, did not seem to excite any 
attention for an investigation of the deeper-seated parts, and the 
animal was allowed to go on unheededly. Having been brought 
into her hovel for a few days, she unfortunately came under the 
influence of the contagion of pleuro-pneumonia, and fell a victim 
to its ravages in a few days. The body was opened within twenty- 
four hours, and under the inspection of a medical friend, a former 
pupil of my class, who, at my request, carefully removed the 
entire organs of generation, and transmitted them to me for exami- 
nation. 
Post-mortem Dissection of the Organs of Generation . — The 
vagina was slit up along its inferior wall into the rectum. In the 
whole of its surface not the slightest morbid condition could be 
observed, except at its angle of attachment to the os uteri. Its 
entire surface was abundantly lubricated with muco-purulent mat- 
ter; but this was not derived from its parietes, but from the os and 
cervix uteri. The passage of the urethra and the interior of the 
bladder were perfectly healthy. The caliber of the vagina was of 
the usual size, and no impediment seemed opposed to complete 
penetration. 
In the os and cervix uteri, however, abundant evidence of dis- 
ease was found. That portion of the uterus that projects into
