60 CAUSES, SYMPTOMS ANL> TREATMENT Ot 



mesenteric glands. It is rare in the lower animals. It is sometimes a 

 sequel of a debilitating disease, as strangles in very young animals. In 

 young cattle it is quite common. In this disease the mesenteric glands 

 become involved, and prevent the introduction of the chyle into the sys- 

 tem, and the result is a gradual decline. It is due to tubercular degen- 

 eration 



Symptoms. — Great emaciation; feces pass in semi-digested state ; pulse 

 weak, not very quick, but quickened to some extent ; belly pendant, or 

 pot-bellied ; muscular system soft and flabby. The animal dies a gradual, 

 lingering death ; abdominal pain in last stages. 



Treatment not very satisfactory. Support the stiength as well as you 

 can by a generous diet. Give iodide of potash ; feed upon the best of 

 food. Iron is beneficial; cod liver oil has been recommended. I have 

 noticed this from .strangles, it usually terminates fatally. Post mortem 

 reveals tubercular degeneration. There may be tubercular deposits in the 

 lungs or some other organ as well. 



Anasarca may come in connection with the limb, due to an accumu- 

 lation of serous fluid. It comes from a percolation of the fluids into the 

 flesh. It may contain a small amount of albumen. There are two kinds 

 — inflammatory, and from venous obstruction. They receive distinctive 

 names from the place in which the fluid accumulates. If in the thoracic 

 cavity, it is hydrothorax. If in the cranial cavity, it is hydrocephalus. 

 If in the tunica vaginalis, it is hydrocele These may come from inflam- 

 mation, or venous obstruction or debility. If from venous obstruction, 

 they will pit upon pressure. It is sometimes found in the human, from 

 standing up for a considerable time ; not due to any particular disease, 

 but may be symtomatic of some other disease, such as diseases of the 

 lungs, kidneys and liver, in which cases you will have well-marked symp- 

 toms in the organ affected, except in the heart. It generall}' occurs in 

 the hind leg, and a term frequently applied to it is stocking. Heavy 

 horses are more subject to it ; legs swell at night ; and it may come from 

 well marked causes, as washing and not drying; exposure and hard work ; 

 horses kept in the stable during winter, and then made to do a hard daj^'s 

 work in the spring, etc. Improper bandaging may produce it, and it is 

 good practice to see to placing a bandage yourself, as it may be put on 

 too tight, and so do more harm than good. 



Sjm/>^om5.— Swelling of the limb, and if not due to inflammatory 

 action, there will be no pain, but in some cases there is some stiffness, 

 and in some thf^re is none. It is common in the spring. 



Treatment. — Keep off work, and give a laxative ; also change the feed, 

 and give a good diuretic ; three drachms sweet spirits nitre, three drachms 

 resin, and sutticient amount of soap, is a good diuretic ball. If you can- 

 not keep off work, hand-rub the leg well, and bandage, but not too tight. 

 Or you may give more powerful remedies— white liellibore, one scruple to 

 one-half drachm, or even one drachm. In cases where there is much 

 swelling, give nitrate and iodide of potash ; but do not push diuretics too 

 far, but give one or two doses, and then have recourse to tonics, regular 

 exercise, and get the system in a good condition ; may give iron in the 

 morning and diuretic at night, or vice versa. This swelling may have a 

 great tendency to become organized. It is more likely to occur in a very 

 old animal. Blisters are entirely inapplicable in such cases. Iodine 

 ointment may be used in some cases, if you just wish to stimulate absorp- 

 tion to a certain extent. Another cause is undue pressure upon the limb. 

 Injury to one foot, and standing upon the other has a tendency to produce 

 it. 



Swelling* ol' the Sheath i.s common. You can generally get rid of
