PLEUHo-PNEUMONIA.
Nature Of the Disease. se.-Appcarances Ar
 ter Death-Its Ravages.

The following in regard to pleuro. pneumonia, the dreaded cattle scourge which has recently broken out il, 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 to 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 Io2 degrees may be locked upon with suspicion; above Ioa degrees or Io5 degrees, they are diseased. The first noticeable indica- tions are the appetite, slower rumina- tion and short dry cough 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 50 far as the other cattle gre concerned.
 In the second stage the animal grows more feverish, stands with its fore legs wide apart and it's mouth open; it shows signs of distress and pain. The breath and bowel dis charges arc fetld. 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. yalescence may be tardy, running through months even, during all of which time the animal may infec, others. The deaths are estimated at from 20 to 25 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 2S per cent.
 Among the predisposed causes of the disease are, distilled food, too rapid fattening, 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 1t as high as I,0oo feet. In Europe, water courses twenty-five feet wide have been known to stay the plague; the limit of contagion is gen erally supposed 10 be from SO to 200 feet.
 The appearances after death are, the lungs enormously enlarged and hepatlzed throughout like sllver;neilh. CT the heart nor stomach is much af, fected. The flesh is in no way differ ent Tn appearance. from that of healthy OK, in the same condition as 10 fat.
 From I'll to I769 this lung pesti fence destroyed POO, 1000, 900 head of cattle in Europe. It reached Prussia Tn 1902, England in I84;I, where, in I855-6, 1t proved fatal to 500, ,ooo head in eighteen months. It came to Brooklyn In IS45, New Jersey in iS44, to Brooklyn again in 1850 and to Boston in 1859. Switzerland ha, tsen called the home of pleuro pneu monia. The conlasion is very subtle; lhe flesh of diseased animal, has con. ycyed the malady.
 Cattle have caught it from graz ing ID pastures or feeding stables months after use by infected stock. All intelligent authorities concur in saving that on hygienic grounds there IS no reason to ir,tr,llct the sale of such n-sh as human food; but due carr should be taken with regard to the spread Of the disease through the meat ri heas,hy cct'l-.
