DISEASES OF SWINE AND OTHER ANIMALS. 335 
__ September 14.—Pig No. 5, both eyes nearly closed; is weak, though not very; ema- 
ciates rapidly ; appetite is poor. No. 6 has its eyes yet open; otherwise about the 
same as No, 5. 
September 15.— Pig No. 5, eyes closed; is very loath to move, and shows plain symp- 
toms of pneumonia. Pig No. 6, too, shows symptoms of pneumonia, but they are less 
pronounced ; 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 sufiering ; neither one seems to be very thirsty. 
September 16.—Pig No. 5 very weak, breathes one hundred times per minute; its 
flanks are working forcibly; slight lameness in left hind leg. Pig No. 6 is also very 
weak, but is yet able to run; passed a large quantity of urine of a bright yellow color. 
The appetite 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 No. 5is extremely weak ; is scarcely able to move; its breathing is 
difficult and distressing. Ng. 6 is about the same as in the morning. : 
Sepiember 17.—Pig No. 5 shows symptoms of dropsy in the chest, and breathes with 
great difficulty, about one hundred times per minute. In the evening the pump- 
ing motion of the flanks is increased, but the respiration is slower—about fifty-six 
breaths per minute. Pig No. 6 is a little more lively than No. 5, but also very sick, 
and has no appetite. Both pigs failed to void any dung from 8 o’clock a. m. to 6 
o’clock p. m. 
September 18.—Pig No. 5 exceedingly emaciated, some rattling noise in the respira- 
- tory passages. Pig No. 6 about the same as yesterday. 
September 19.—Pig No. 5 emaciated to the utmost, but otherwise apparently not 
worse. Pig No. 6 shows apparent improvement; is a little livelier than before; has 
some appetite; consumed one ear of corn during the last twenty-four hours. In the 
eyening pig No. 5 breathes with the greatest difficulty, one hundred and four times per 
minute. No. 6 unchanged. 
September 20.—Pig No. 5 very sick; hreathes with great difficulty.. No.6 apparently 
improving. 
September 21.—Pig No. 5 just alive. Both pigs have been lying nearly all dayin one 
corner of their sty, their noses buried in the bedding. In the evening pig No. 5 is per- 
spiring ; 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 constipated, but now has diarrhea; feces 
grayish-green, semi-finid, and exceedingly fetid. Pig No. 6 is less emaciated than No. 
5, has no diarrhea, and.eats a little. Urine of No. 5, examined under the migoscope, 
contained innumerable bacillus-germs (micrococci of Hallier), and a few bacilli suis.* 
(See drawing I, fig..1.) 
September 23.—Pig No. 5 a mere skeleton, and extremely weak; breathes only forty- 
eight times per minute. Pig No. 6 not quite so low; breathes only thirty-six times 
per minute. In afternoon pig No. 5 too weak to stand on its legs; breathes fifty-two 
times per minute ; is sweating; the sweat cold and clammy. Seeing that the animal 
could not possibly live till next morning, and desiring to make the post mortem exam- 
ination before putrefaction should set in, I killed pig No. 5 by bleeding at 6 o’clock 
“p.m. (As to result of post mortem examination, see chapter on Morbid Changes. ) 
September 24.—Pig No. 6 very sick; eats scarcely anything. 
September 25.—Pig No. 6 shows slightly increased appetite, and fully as much, if not 
more, liveliness than on any day last week. It almost seems as if some real improve- 
ment is going on, notwithstanding very serious morbid changes must have taken 
lace. 
: September 26.—Pig No, 6 eats some in the morning, but does not seem to care for 
any food at noon; appears to be a trifle bloated; droops its head, and holds its nose 
to the ground. 
September 27.—Pig No. 6 decidedly worse; breathes seventy-two times per minute; 
head drooping; nose to the ground; back arched; skin very dry and hard to the 
touch; no appetite whatever. 
September 28.—Pig No. 6, which was very low last night, has somewhat reeuperated, 
and is moving again; consumed some water, and also a little food. 
September 29.—Pig No, 6 exceedingly emaciated and yery weak; breathes thirty- 
eight times per minute ; holds its nose persistently to the ground, and has no appetite 
whatever. 
September 30.—Found pig No. 6, at 7 o’clock a. m., lying dead in a corner of its sty.

*T have chosen the name ‘‘bacillus suis” because the bacilli, as will appear hereafter, seem to be pe- 
culiar to swine-plague, and haye not been before named as far as I have been able to learn.
