particularly if, as is frequently the case, an obstinate purging supervenes. _Post-mortem._ The whole cellular tissue is found to be infiltrated, and a yellow serous fluid everywhere follows the knife. The muscles are soft and flabby, having the appearance of being macerated. The kidneys are pale, flaccid, and infiltrated. The mesenteric glands are enlarged, and engorged with yellow serous fluid. The belly is frequently filled with water, or purulent matter; the peritoneum is everywhere thickened, and the bowels adhere together by means of an unnatural growth. The heart is enlarged and softened, and the lungs are filled with tubercles. The principal alterations of structure are in the liver, which is pale, livid, and broken down with the slightest pressure; and on being boiled, it will almost dissolve away. When the liver is not pale, it is often curiously spotted; in some cases it is speckled, like the back of a toad; some parts of it, however, are hard and schirrous; others are ulcerated, and the biliary ducts are filled with flukes. The malady is, unquestionably, inflammation of the liver. This fluke is from three-quarters of an inch to an inch and a quarter in length, and from one-third to one-half an inch in its greatest breadth. These fluke-worms undoubtedly aggravate the disease, and perpetuate a state of irritability and disorganization, which must necessarily undermine the strength of any animal. _Treatment._ This must, to a considerable extent, be very unsatisfactory. After the use of dry food and dry bedding, one of the best _preventives_ is the abundant use of pure salt. In violent attacks, take eight, ten, or twelve ounces of blood, according to the circumstances of the case; to this, let a dose of physic succeed--two or three ounces of Epsom salts; and to these means add a change of diet, good hay in the field, and hay, straw, or chaff in the yard. After the operation of the physic--an additional dose having been administered, oftentimes, in order to quicken the action of the first--two or three grains of calomel may be given daily, mixed with half the quantity of opium, in order to secure its beneficial, and ward off its injurious effects on the ruminant. To this should be added common salt, which acts as a purgative and a tonic. A mild tonic, as well as an aperient, is plainly indicated soon after the commencement of rot. The doses should be from two to three drachms, repeated morning and night. When the inflammatory stage is clearly passed, stronger tonics may be added to the salt, and there are none superior to the gentian and ginger roots; from one to two drachms of each, finely pounded, may be added to each dose of the salt. The sheep having a little recovered from the disease, should still continue on the best and driest pasture on the farm, and should always have salt within their reach. The rot is not infectious. SCAB.
