378 REPOET OF THE COMMISSIONER OP AGRICULTURE. 



exudation used was perfectly free froju any putrid smell, and contained, csamiued 

 under the microscope, numerous bacillus-germs, and some haciUi. 



Jioie 10. — No visible reaction in eitht-r animal. 



'June 11. — Ifeilcr No. 'J, no change, escej>t a very slight Rwelliug attacked by a few 

 liico at the placf) of iuocuhition. 



June 12. — Heifer No. 2, changeable appetite. 



June 13. — Heifer No, 2, no morbid symptoms whatever; temperature, 102° F. 



June 14. — Both heifers apx)arently in first-rate health. 



June 15.-— Heifer No. 2 shows signs of illness; breathes fifty-six times a minute; muz- 

 zle dry and alinormally ■warm ; appetite slow and irregular; eyes somewhat tlull. 



Jinte Ifi. — Heifer No. 2 shows at times plain indications of illness, and at times seema 

 to be all right ; conghs some ; dung rather hard, uark-tolored, and coated with sticky 

 mucus. Tempei-ature, 103.4° F. 



Jiiiie 17. — Heifer No. 2 evidently sick ; muzzle dry and hot; appetite irregular and 

 changeable; dung hard and dark-colored as yesterday; resiDiration accelerated. The 

 animal acts rather dull, and shows a tendency to lie down. Temperature, 103.6° F. 



June 18. — Heifer No. 2, in the forenoon the same as yesterday, except the temperature, 

 which was as low as 102-^ F. In the afternoon apparent improvement ; muzzle moist, 

 but temperature 103'^ F. 



Heifer No. 1, till date, has not exhibited any conspicuous symptoms of disease; at 

 least none has been observed by Mr. Moore, who keeps the animal in his pasture, and 

 is perfectly famili-'ir with all the various symptoms of swine plague. Examined the 

 animal at 9 o'clock, a. m., and found the muzzle diy and abnormally warm; the 

 breathing accelerated, and the temperature, taken without any struggling or resist- 

 ance, 103.G° F. 



June 19. — Heifer No. 2, no essential change; muzzle sometimes moist, sometimes 

 dry; temperature, 103.4° F. 



June 20. — Heifer No. 2 about the same: dung of the consistency of stiff dough, and 

 blackish in color (the food consists of very good hay, some oats, and occasionally some 

 bran or chop-feed); temperature, 103.5° F. 



June 21. — Heifer No. 2, no essential change; breathing a little more accelerated, but 

 the eye somewhat brighter; temperature, 103.6° F. 



June 22. — Heifer No. 2. no essential change ; temperature, 104° F. 



June 23. — Heifer No. 2, temperature in the morning, 104.4° F, ; in the evening, 

 103° F. 



June 24. — Heifer No. 2, temperature in the morning, 103° F. Inocnlated the same 

 in the evening once more by means of a hypodermic syringe with ten drops of the 

 pulmonal exudation of Mr. Fhilippi'a pig. 



June 25. — Heifer No. 2 leas; lively, more dumpish than on preceding day ; temperatoro, 

 103.0° F. 



June 26. — Heifer No. 2, no essential change; temperatgre, 104° P. 



June 27. — Heifer No. 2, about the same; temperature, 103.7° F. 



June 28.:— Heifer -^q, 2, appears to be move lively; appetite improved; temperature, 

 103° F. 



June 29. — Heifer No. 2 eats and drinks well ; muzzle moist ; temperature, 103.6° F. 



June 30. — Heiier No. 2, muzzle hot and dry in the morning. Took at 1 o'clock, p. 

 m., a few drops of blood from a vein of its left car, which,- examined under the micro- 

 scope, contained a few moving haciUi and several clusters of bacillus-germs (see draw- 

 ings). The temperature, taken at the same time, was only 102° F. At 6 o'clock, p. 

 m., respiration lifty-six brealhs in a minute, and temperature 104.4° F. 



Heifer No. 1, examined in the afternoon, appeared to be all right. According to Mr, 

 Moore, it had acted dumpish and been out of appetite for a few days, but had recovered. 

 So it may be concluded th.it heifer No. 1 has had a very mild attack, but its vigorous 

 constitutaon has enabled it to overcome the efiects of the infectious principle. 



Jul)/ 1. — Hciftfr No. 2, muzzle hot and dry; temperature 103.8° F. 



./(//// 2. — neifer No. 2, mnzzle moist ; respiration accelerated ; the animal brcatheg 

 over sixty times a minute : auscultation reveals a slight rubbing sound, and increased 

 l)ronchi:ii breathing; temperature 104.6° F. In the evening temperature down to 

 10r.° F. 



Jul;/ 3.— Heifer No. 2, temi>€rature at 9 o'clock, a. m., 103.6° F. (It may be remarked 

 here that heifer No. 2, during the whole experiment, had a; verj-^ quiet, clean, and 

 moderately dark stall, 5x10, where she was not at all, or but very little, mole&ted by 

 flies, where tlie air was always pure, and where nothing occurred liable'to raise tho 

 temperature of the body above normal; on tho contrary, where the conditions were 

 ratlier such as to keep the temijerature at the lowest point, because the animal was 

 tied, h."«d no exei-cise, and was naturally of a very quiet and docile disposition. It 

 scarcely ever offered any resistajice while being examined.) 



At 9.15 o'clock, a. tii., lieifer Ko. 2 was killed by bleeding by a pro- 

 fessional biUclxer.
