GLANDULAR ABSCESSES. 
The pulse was small and wiry; the respiration difficult, and 
even painful, and accompanied by a peculiar contorsive motion of 
the sides ; a loud vascular sound was audible at the upper part 
of both lungs ; and where this sound was less appreciable, another 
sound or rattle commenced, passing chiefly through the large 
bronchial divisions, and recognised, in treatises on auscultation, 
under the name of crepitous rale. 
This sound, when it exists in pleurisy, announces that the pul- 
monary pleura has, at the bottom of the thoracic cavity, contracted 
some adhesions with the costal pleura ; it also indicates the limits 
of the effusion. The animal could hardly stand, with its fore-legs 
set apart from each other, to facilitate the entrance of air into the 
lungs, tottering as it did beneath the weight of the body. Its face 
was distorted ; the eye brilliant, the pupil dilated, the extremities 
cold ; in a word, there was every sign of agony. He did not die 
until the following morning, some moments after he had fallen 
down upon his litter. 
Post-mortem examination . — On opening the body, which was 
done shortly after death, numerous lesions were found, some ap- 
pertaining to the primitive disease, that is to say, to the swelling 
of the seton, and others to a consecutive inflammation of the glands 
at the entrance of the chest and of the pleura. 
The first, which were almost immediately subcutaneous, existed 
in the actual course of the seton, whence all the evil had arisen. 
There was found an indurated tissue giving out a grating sound 
under the knife, and displaying every here and there little lumps 
or swellings, constituting so many abscesses, isolated from one 
another, having thick coverings, and containing a yellow fibrous 
pus. On a level with the entrance to the chest was found a fistu- 
lous wound, through which, a few days before, had flowed the pus 
contained in the glandular abscess. The membrane which lined 
the interior of this abscess (pyogenic membrane) was covered with 
cellulo-vascular buds, the two largest of which had in their centres 
openings into a fistulous passage, which formed the communication 
between these abscesses and other and more deeply situated purulent 
deposits. These latter were surrounded on all sides by lymphatic 
glands, many of which had already begun to soften ; while others, 
and by far the greater number, when cut open, only displayed a 
reddish-brown tissue, greatly inflamed, easily torn, and appearing, 
like the substance of the kidneys, to be radiated from the centre 
towards the circumference. The first mentioned, that is to say, 
those which presented several soft spots about the centre, commu- 
nicated with each other by means of fistulous passages, which ap- 
peared to us to be neither more nor less than the lymphatic vessels 
which, in a natural state, pass from one of these glands to ano- 
ther.
