188 DISEASES OF THE HOESE. 



which may occasionally be scraped off. If sheep-skins cannot 

 be procured, the liniment should be repeated with the addition 

 of half a drachm of croton oil, or a mustard poultice may be 

 aj^plied to the loins. 



A draught should next be given composed of 4 drachms of 

 aloes, and a pint of linseed oil. 



The horse should be allowed plenty of thin linseed tea and 

 warm bran mashes, if he will eat them. 



Copious injections should be frequently thrown up, both to 

 remove the costiveness, and to act as a fomentation. 



If the urgency of the symptoms are not materially abated in 

 the coui'se of six hours, the bloodletting should be repeated, 

 and a scruple of white hellebore, administered twice a day, with 

 a few drachms of gum arable. 



When the horse gets better, the pain Is considerably dimi- 

 nished, as well as the tenderness of the loins, and the urine be- 

 comes gradually of a lighter colour. 



Cai-e must be taken that the horse is not worked too soon, 

 particularly with heavy draughts or burdens. — Ed.] 



Hcematiiria. 



[Bloody urine is sometimes discharged without any appearance 

 of inflammation or constitutional affection ; it is then called H(b- 

 viaturia, and often arises from sudden exertions or strains, when 

 perhaps some small blood-vessel becomes ruptured. 



The horse should be rested, bled, and physicked ; and if the 

 symptoms are very severe, the «ame treatment should be era- 

 ployed as in inflammation of the kidneys. — Ed.] 



It sometimes happens, however, that the urine becomes foul 

 and stimulating from high or unwholesome feeding. In this 

 case the bladder will contract upon a small quantity of urine, 

 and the urine may be rather high-coloured like beer, or turbid 

 like whey, and the horse may appear to strain a little in voiding 

 it ; but this is very different from those distressing symptoms 

 which attend inflammation of the kidneys, nor is it accompanied 

 with loss of appetite, or, any degree of fever, which is always 

 present in inflammation of the kidneys. When the urine be- 

 comes thus stimulating, some cold mashes, with a little nitre, 

 may be given, or what is still better, perhaps, some grass, vetches, 

 or lucerne. If the horse is at all costive, a clyster should be 

 thrown up. An infusion of linseed is a good drink for a horse 

 Avhen the urine is in this state. There are other diseases of the 

 kidneys by which their functions are interrupted, at first par- 

 tially, and with considerable intermissions or remissions, but 

 after a time wholly and permanently. One of these diseases is 

 a gradual decay of the kidney; another is a gradual enlarge-
