DISEASES OF SWINE AND OTHER ANIMALS. 23 



September 15. — Pig is o. o, eyes closed ; is very loath to move, and 

 shows plain symptoms of pneumonia. Pig ISTo. G, too, shows symptoms 

 of pneumonia, but they are less jjronounced ; is without appetite, and 

 Just as much emaciated as No. 5. The skin of both animals is hard and 

 dry ; and their coat of hair rough and staring ; their bowels are costive ; 

 but little dung is voided. Both animals betray plain indications of pain 

 and sufi'ering ; neither one seems to be very thirsty. 



September 10. — Pig No. 5 very weak, breathes one hundred times per 

 minute ; its flanks are working forcibly ', slight lameness in left hind leg. 

 Pig Xo. is also very weak, but is yet able to run ; passed a large 

 quantity of urine of a bright yellow color. The ax)petite of both pigs 

 for food is reduced to nothing, but both exhibit a vitiated appetite, and 

 eat each other s dung, or their own, as soon almost as it drops. The 

 skin is very hard to the touch, parchment-like, and seems to stick to the 

 bones. In the evening pig IsTo. 5 is extremely weak ; is scarcely able to 

 move ; its breathing is difficult and distressing. No. G is about the same 

 as ui the morning. 



September 17. — Pig No. 5 shows symx>toms of dropsy in the chest, and 

 breathes with great difficulty, about one hundred times per minute. In 

 the evening the pumping motion of the flanks is uicreased, but the res- 

 piration is slower — about fifty-six breaths per minute. Pig No. G is a 

 little more lively than No. 5, but also very sick, and has no appetite. 

 Both pigs failed to void any dung from S o'clock a. m. to G o'clock p. m. 



September 18. — Pig No. 5 exceedingly emaciated, some rattling noise 

 in the respiratory passages. Pig No. G about the same as yesterday. 



September 19. — Pig No. 5 emaciated to the utmost, but otherwise ap- 

 parently not worse. Pig No. G shows apparent imjirovement ; is a little 

 livelier than before; has some appetite; consumed one ear of com dur- 

 ing the last twenty-four hours. In the evening pig No. 5 breathes with 

 the greatest difficulty, one hundred and four times per minute. No. G 

 unchanged. 



September 20. — Pig No. 5 very sick; breathes with great difficulty. 

 No. G apparently improving 



September 21. — Pig No. 5 just ahve. Both pigs have been lying nearly 

 all day in one comer of tlieir sty, their noses buried in the bedding. 

 In the evening pig No. 5 is perspiring ; sweat cold and clammy. 



September 22. — Pig No. 5 breathes sixty-four times per minute, with 

 jerking motions of the flanks, and so far has been more or less consti- 

 pated, but now has diarrhea ; feces grayish-gTeen, semi-fluid, and ex- 

 ceedingly fetid. Pig No. G is less emaciated than No. 5, has no dianhea, 

 and eats a little. Urine of No. 5, examined under the microscope, con- 

 tained innumerable bacillus-germs (micrococci of JIallier), and a few 

 bacilli suis.* (See drawing I, fig. 1.) 



September 2;J. — Pig No. 5 a mere skeleton, and extremely weak; 

 breathes only forty-eight times per minute. Pig No. G not quite so low ; 

 breathes only thirty-six times ])er minute. In afternoon ])ig No. 5 too 

 weak to stand on its legs ; breathes fifty-two times ]>er minute ; is sweat- 

 ing; the sweat cold and clammy. Seeing that tlu^ animal could not 

 possibly live till next morning, and desiring to make the post-mortem 

 examination before putrefaction should set in, 1 killed pig No. 5 by 

 bleeding at G o'clock p. m. (As to result o\^ posit-mortcm examination, see 

 chapter on ]\rorbid Changes.) 



September 24. — Pig No. G very sick; eats scarcely anything. 



*I Lave chosen the name '^hactUuH sjjjs" because the hac'dli, as will appear here- 

 after, seem to be peculiar to s\viue-])lagnc, and have not been before uauicd as far an 

 I have been able to learn.
