520. Catarrh, with Chest Complications, is of a more critical 

 character, as the lungs, bronchial tubes, pleura, and the heart coverings 

 become implicated. The breathing is very much quickened, and the 

 temperature runs up to io6^ and 107° F., while the eyes and nose 

 discharge quantities of matter. The symptoms are somewhat similar 

 to those seen in Bronchitis (par. 506), and the Treatment should be 

 as stated in pars. 507 and 508. 



521. Catarrh and Bilious Fever. In these cases the distinguish- 

 ing difference in the symptoms is the yellowness of the under-side of 

 the eyelids, and the lining membrane of the nose and mouth. The 

 attack may come on suddenly with slight symptoms of colic ; or it 

 may crawl on insidiously for two or three days before making itself 

 manifest, when the animal becomes very dejected and weak. The 

 Treatment is similar to that noted for the two former cases, with the 

 addition of small doses of calomel, which I find to answer well when 

 given in half-drachm doses in a little mash, or in a ball every eight 

 hours, until three doses are administered. 



522. CEdematous or Exudative Cellulitis, commonly called 

 Pink-eye, is recognisable by the legs and eye-lids becoming swollen. 

 The lining membrane of the eye-lid, nose, and mouth are in such cases 

 of a pink colour. Pink-eye is of a very variable character ; at times it 

 is so slight that scarcely anything amiss can be noticed, only the eye- 

 lids are puffed-up, with a watery discharge coming from the corner of 

 the eye, and one or more of the legs may be slightly swollen about the 

 joints and shanks. At other times the eyes, face, and muzzle are 

 much enlarged, and the legs very much distended. The animal 

 refuses its food, can scarcely stir, is very languid and much depressed, 

 breathing becomes quick, and the temperature rises up to 103^ and 

 106° F. Treatment: Hypo-sulphate of soda may be given night and 

 morning in two ounce doses, with drachm doses of sulphate of quinine 

 every eight hours. In some cases, chlorate of potass and iron tonics 

 answer well. Further treatment and feeding should be as noted in 

 par. 508.
