CONTRIBUTIONS TO THE PATHOLOGY AND 
work of a moment ; when I found, upon looking down into the 
tube itself, that it was more than three parts filled with what 
appeared to be a circumscribed egg-shaped tumour, which, on 
cutting down upon and puncturing, I found to be filled with very 
thick whitish purulent matter. The mucous membrane forming 
the roof of the tumour was healthy, and unchanged in its natural 
light pink colour; the quantity of matter liberated would at least 
be three ounces by measure. The cartilages upon which this pu- 
rulent matter rested were very much thickened, and, upon cutting 
into them, all I could observe were three black patches, situated 
within their centre. The heart, and the large vessels in immediate 
connexion with it, were all healthy, and, when divested of its 
fat and large vessels, weighed exactly eight pounds eight ounces 
avoirdupois. I also examined the brain and the spinal cord, and 
found their tissues in a very healthy state. 
Case III . — Hemorrhage of the Liver , Disease of the Heart , fyc. 
September 25 th , 1847 — I was requested, about ten o’clolock, A.M., 
to attend upon a horse, the property of Messrs. Nowell and Hat- 
tersley, railway contractors, in this town. 
History , §c . — The animal is of a grey colour, of the very heavy 
draught breed ; stands sixteen hands two inches high ; is consi- 
dered, upon good data, to be about ten years of age, and has been 
the property of his present owners between three and four years, 
during which period he has always been well kept and well 
worked. For the last fifteen months the animal has been em- 
ployed at Huddersfield, upon the line of railway which is making 
between here and Manchester. 
The horse is affected with a cough, which is hard, dry, and 
loud-sounding; and, in addition, is considered to be also affected 
in his wind. I have at various times given him balls to remedy 
these defects, but without avail, save in a temporary manner. On 
several occasions he has been attacked with fits of vertigo, which 
have manifested themselves very suddenly, particularly when 
made to walk quick, if journeying up hill. I cannot ascertain 
how long the animal has thus been subject to vertigo ; but the 
horsekeeper says, that, about two years and a half ago, this horse 
was employed for some weeks working in deep water; that he 
had a very severe attack of inflammation of the lungs in conse- 
quence, from which resulted the fits, the cough, and the affected 
wind. During the winter I attended him for an attack of epidemic 
catarrh ; and also, on two occasions since, for colic. This morning 
he did not eat well, and, when taken to work, he appeared dull and 
blundering in his movements. After working about an hour, he 
became so weak as to be incapable of further exertion, and the
