PLEURO-pNEUMoNIA.
Nature of the Disssse.--appearances Al
 ter Death--Its Rayages.

The followlnS ln regard 10 picuro'
 pneumonia, the dreaded cattle scourge which has recently broken out iu
 Chicago and other points, is gleaned
 from the very best authorities on the
 subject in America, England, France and Germany.
 The disease is divided into two stages. In the first Stage the blood
 is viscid and thick, in the second dark and fluid. The dark may last from two 10 six weeks. The earliest sign is given by the thermometer; un. der one hundred degrees the cattle may be considered healthy, above that and under ioa degrees may be locked upon with suspicion; above Ioa degrees or Ios degrees, they are diseased. The first noticeable indica- tions are the appetite, slower rumina. tion and short dry congh which in. creases. The breath quickens from fifteen to twenty or thirty per min. ute, the hair loses its lustre, etc. This is the most dangerous stage So far as the other cattle gre concerned.
 In the second stage the animal grows more feverish, stands with its fore legs wide apart and its mouth open; it shows signs Of distress and pain. The breath and bowel dis. charges are feud. It froths at the mouth, ihe eyes and nostrils dis. charge. The animal wastes away and dies in from nine days to three weeks. The disease is more rapid with young and vigorous animals. Recovery may take place in either stage, but con valescence may be tardy, running through months even, during all of which time the animal may infect others. The deaths are estimated at from 20 to $ per cent in mild inva- sions. In severe epidemics they range as high as 90 per cent. The average of exposed cattle which take the dis ease Tn this country has been estimated at sS per cent. ....
 Among the predisposed causes of the disease are, distilled food, too rapid fatlening, excessive milking, marshy pastures, cold, damp exposure, hot damp stables, changes of food and of climate, overcrowding, etc. Authorities differ on the distance which the infection may be carried through the air; some say not more than twelve to eighteen feet; others place it as high as I 1000 feet. In Europe, water courses twenty-five feet wide have been known to stay the plaguej the limit of contsgion is gen. orally supposed 10 be rom so to 200 feet.
 The appearances after death are, the lungs enormously enlarged and hePatized throughout like silver;neith CT the heart nor stomach is much aE. fected. The flesh is in no way differ. ent in appearance from that of a | healthy OK, in the same condition as to fat.
 From 17II to I769 this lung pesti- fence destroyed 200, ,ooo, 900 head of cattle in Europe. IL reached Prussia | in 1892, England in IS4I, where, in | IS55-o, Il proved fatal to 500, 900 head Tn eighteen months. It came 10 l Brooklyn in IS43, New Jersey in IS44, to Brooklyn again in 1850 and | to Boston in 1859. Switzerland has been called the home of pleuro pneu. monia. The contagion is very subtle; the flesh of diseased animals has con. | veyed the malady.
 Cattle have caught it from graz. | ing In pastures or feeding stables months after use by infected stock. | All intelligent authorities concur m saying that on hygIenic grounds there IS no reason 10 inttrdict the sale of such flesh as human food; but due care should be taken with regard to the spread oi the disease through lbe meat of healthy cattle. The flesh of mil. lions Of such diseased animal. has been con umed in various pats of the world. yet there has never beer case where injurious consequences have been traced to its use And as with he flesh, so with the milk, which the most enlightened phJ sician p,onoun. ces harmless.-New York Market Jcuinal.
