to plethora— a bloodless state. The circulating fluid lacks 

 the elements of nutrition, and the animal is weak, flabby, 

 wasted, and rapidly wasting. The mucous membranes 

 are pale, the pulse weak and small, and the heart sounds 

 are strangely audible. Dropsical swellings appear beneath 

 the jaws, on the lower parts of the abdomen, as well as 

 inside, causing a " pot-bellied " appearance. The appe- 

 tite is lost, the bowels are noisy, and wind passes con- 

 stantly from them. Diarrhoea comes on later, and pro- 

 bably causes a lingering death; otherwise an offensive 

 dysentery terminates the sufferings. 



Treatment.- — Remove the cause. Supply good food in 

 moderate and regular quantities, with attention to fresh 

 air and water. Treat the diarrhoea as advised (p. 208) ; 

 followed by tonics 4 or 5, and later alternated with 1 

 or 2. 



Rheumatism.— The Cold, Joint, or Chine Felon of the 

 old farriers. This disease is due to the state of the blood, 

 having its origin in impaired digestion and assimilation ; 

 it is charged with elements inimical to its constitution, an 

 arrest of function probably being the cause of their accu- 

 mulation and non-removal. The joints are the usual 

 seat of the malady, the offending element locating itself 

 in the substance of cartilage, bones, and tendon, which 

 enter into the formation of the parts. The heart, with its 

 coverings, and the lining membrane of the chest, are also 

 liable to participate seriously and fatally. 



Treatment. — Aperients, followed by febrifuges in the 

 acute stages, morning and evening. Hot fomentations 

 are also useful, followed by sedative embrocation No. 2. 

 After the pain and inflammation are subdued, No. 4 may 

 be substituted, twice daily. Fresh air and gentle exer- 

 cise are essential as recovery progresses. Subcutaneous 

 Injections, No. 2. 



Ur/Emia is a condition of blood poisoning by the 

 retention of those elements which should pass out by the 

 urine. The skin exhales a strong and sickly odour of 

 urine in fully developed cases, the mouth is offensive and 

 slimy, and the faeces are small, hard, glazed and likewise 

 offensive. The end then rapidly approaches ; dulness
