DISEASES OF DOMESTIC ANIMALS. 59 



ward. Pressing on the cord on the inside of the leg causes pain, and he 

 will lift the leg quickly. Swelling may extend entirely around the leg. 

 It is very painful. Pulse full and bounding duriug inflammation. 

 Usually the sthenic type of inflammation ; pulse fifty or sixty beats per 

 minute ; breathing much aftected ; bowels costive ; urine high coloured ; 

 pain local and constitutional ; will perspire, not profusely, but just be- 

 dews the body to some extent. Appetite gone, and great thirst, caused 

 by fever, and if relief is not given soon, effusion will take place, and may 

 take on suppurative process. In glanders we have lymphangitis, from 

 poison in the bood. Animal generally stands; does not want to move, 

 but sometimes, from excessive pain, will lie down, and has great difficulty 

 in getting up. Will look at the sides, as in colic. Sometimes milder in 

 the fore than in the hind legs. The parts may regain their natural 

 appearance, but it has a tendency to leave the leg enlarged, especially 

 from repeated attacks. There is some l}Tnph left, which becomes organ- 

 ized and cannot be removed. 



Treatment. — If in a strong animal, from too much chyle, get rid of it 

 as quickly as possible, by giving from eight to ten drachms of aloes ; may 

 give II little calomel ; will derive benefit from tincture of aconite, eight 

 to ten drops at a dose. Give nitrate of potash freely. Give clysters of 

 soap and water. If inflammatory action is of a sthenic type, blood-letting 

 may prove a benefit, but in many cases is not necessary. If you do 

 bleed, do not give so much purgative. It is not material whether you 

 bleed from saphena or jugular vein. 



Local Treatment. — Judicious use of fomentations, but not too hot ; 

 your hand can bear more heat than the horse can ; Use cautiously ; 

 bathe for two, three or four hours. It increases swelling, and encourages 

 exudation Keep heat to the parts as well as you can Hay rope is quite 

 good. Prevent reaction from taking place, by using mild stimulants, 

 camphorated liniments. If there is pain, you may relieve with bella- 

 donna or laudanum. Keep the animal quiet. Give exercise after the 

 inflammatory action has passed off but not before It does reduce the 

 swelling, but it soon returns, and is more difficult to treat than before 

 exercising. Give plenty of cold water. It is sometimes better to with- 

 hold food for twenty four hours, and constitutional stimulants are not 

 very useful. 



Elephantiasis. — Thickening of the limb from repeated attacks of 

 lymphangitis, and may result from one attack, but generally from 

 repeated attacks. From the swelling there remains a slight swelling ; 

 some exudation is left. It swells again, and more exudations ; blood 

 vesse's pass into it ; also nerves, and it is converted into new str. cture. 

 If the ania-al stands over night say twenty-four hours, the limbs become 

 swollen, which exercise will relieve to a certain extent. It sometimes 

 comes from repeated attacks of grease, but more likely to come from 

 lymphangitis, especially if treated with hot liniments. If it is com- 

 pletely established, you can never restore the limb to its natural condi- 

 tion ; but you may give gentle exercise. Give purgative, then diuretic 

 medicine, and hand-iubbing and bandaging may be of use, if he is 

 not fed too high, and is moderately exercised. There is another con- 

 dition of the lymphatics from lymphangitis. It is a dilation of the 

 lymphatics. The walls become dilated or varicose ; these small tubes 

 become obstructed. This is most likely to occur in connection with 

 elephantiasis. There may be rupture of the blood vessels, and not 

 only of th6 vessels of the limb, but it may occur in connection with 

 some of the internal vessels in connection with the mesentery.
