310 JAUNDICE. 



If horses, destroyed on account of other complaints, are examined when they 

 are not more than five years old, the liver is usually found in the most healthy 

 state; but when they arrive at eight or nine or ten years this viscus is fre- 

 quently increased in size— it is less elastic under pressure — it has assumed more 

 of a granulated or broken down appearance — the blood does not so readily per- 

 meate its vessels, and, at length, in a greater or less quantity, it begins to exude, 

 and is either confined under the peritoneal covering, or oozes into the cavity of 

 the belly. There is nothing for awhile to indicate the existence of this. The 

 horse feeds well, is in apparent health, in good condition, and capable of con- 

 stant work, notwithstanding so fatal a change is taking place in this important 

 viscus; but, at length, the peritoneal covering of the liver suddenly gives way, 

 and the contents of the abdomen are deluged with blood, or a sufficient quan- 

 tity of this fluid has gradually oozed out to interfere with the functions of the 

 viscera. 



The symptoms of this sudden change are pawing, shifting the posture, dis- 

 tension of the belly, curling of the upper lip, sighing frequently and deeply, the 

 mouth and nostrils pale and blanched, the breathing quickened, restlessness, 

 debility, fainting, and death. 



On opening the abdomen, the intestines are found to be deluged with 

 dark venous blood. The liver is either of a fawn, or light yellow, or brown 

 colour— easily torn by the finger, and, in some cases, completely broken 

 down. 



If the hemorrhage has been slight at the commencement, and fortunately 

 arrested, yet a singular consequence will frequently result. The sight will 

 gradually fail ; the pupil of one or both eyes will gradually dilate, the animal 

 will have gutta serena, and become perfectly blind. This will almost assuredly 

 take place on a return of the affection of the liver. Little can be done in a 

 medical point of view. Astringent and styptic medicines may, however, be tried. 

 Turpentine, alum, or sulphuric acid, will afford the only chance. The veteri- 

 nary world is indebted to the late Mr. John Field, for almost all that is known 

 of this sad disease.
