Liver Diseases, or the farriers’ “Yellows,” so called from the fact that such cases are marked by the eyelids, linings of the nose, and lips when turned up, being found to be tinged more or less with yellow.

Here mercury must be administered, and aided by subsequent purging, as is necessary with the human subject.

Thus, give half a drachm to a drachm of calomel mixed in a little flour, and put in a mash of bran one evening, and next morning follow it up with the aloes purge-ball ([page 108]).

If the “yellows” be very marked, with other derangement of the system, give for two days one drachm of calomel daily in doses of half a drachm each, mixed in mashes as described above; and after two drachms have been taken in this way, administer on the third morning the aloetic purge.

Inflammation of the Kidneys and Bladder.—With regard to internal inflammation arising from various causes, the symptoms of distress bear a general resemblance to each other: legs spread out, extremities cold, breathing accelerated, and a look of pain pervading the animal’s whole appearance, except that in diseases of the urinary organs there is generally a straddling gait; and on observance of the genitals, some marked action in this region on the part of the beast will be discovered.

Such attacks can only be properly treated by a professional man, therefore lose no time in procuring his services; but, in the meanwhile, I shall observe that inflammation of the kidneys is, sad to say, too common to admit of its being passed by without offering some caution and advice regarding it, more for the purpose of prevention than cure.

Disease of the kidneys is generally brought on by the misuse by grooms of their favourite diuretics; a dose of nitre to “fine his legs,” or “bloom his coat,” or for any other purpose to save themselves trouble, is the groom’s specific for the poor creatures under their care; but so injurious are diuretics that masters ought to make their secret administration, as commonly practised by the class referred to, a case of instant dismissal.

The kidneys of the horse are peculiarly susceptible of action; so much so, that purges frequently, in place of acting as intended, will take effect on them.

It should, besides, be borne in mind that while the kidneys are in artificial action and secreting an extra quantity of urine which is being passed away, the creature should have the same opportunity of rest, and as much consideration given him, as if he were in a state of purgation. The secretion is blood in its changed form, and is a serious call on the system. All this does not enter into the head of an ignorant groom, who, on the contrary, will work or treat the poor suffering creature as if he was in his best vigour.
