ON THE IlE-ABSORPTION OF PUS. 
fest itself; but it had made fearful progress, and the animal was 
brought to the hospital. 
He was exceedingly feeble—sadly depressed—without appe¬ 
tite—the nostrils dilated—the flanks heavy—the respiration ac¬ 
celerated and irregular—the expired air penetratingly fetid—and 
there ran from the nose a little rose-coloured fluid with a well- 
characterized gangrenous smell. Auscultation was had recourse 
to; nothing was to be heard but a very feeble respiratory mur¬ 
mur in the left lung—a much more feeble one in the right—and 
no murmur at all in many parts of both lungs, and particularly 
of the right lung; nevertheless, both sides of the chest resounded 
loudly on percussion. 
Diagnostic. —Gangrenous inflammation of the right lung and 
of some part of the left one. 
Prognostic. —Death at hand. 
It is of importance to remark, that, two days before the ap¬ 
pearance of the disease in the lungs, the owner had ob¬ 
served a diminution, and then a complete suppression, of the 
suppuration of the wound on the side. It was on the day of the 
suppression that he was attacked with pneumonia. When he 
was brought to the hospital the wound had a livid redness round 
it, with a leaden tint at its centre, where opened a fistula which 
extended three inches forwards under the subcutaneous muscle. 
Treatment. —The application of a mild vesicatory ointment to 
the wound; chloruretted fumigations; an electuary containing 
two ounces of bark and two drachms of camphor; nitrated white 
drinks. 
He died in the night of the 30th and 31st. 
Opening, four hours after death. —The internal surface of the 
chest beset with numerous ecchymoses. The left lobe of the lung 
equally ecchymosed on some points of its surface, and presenting 
within, ten or tioelve gangrenous spots, varying in size from that 
of a small nut to a pulled s egg. The centre of each of these little 
masses was composed of a purulent matter, of a white grey colour, 
and mingled with broken doioi gangrenous particles. These 
morbid products had no determined envelope—their limits were 
those of the mortified tissue. The cellular tissue between them 
was sound; but there was one portion of this tissue so infiltred 
with blood, that it resembled a clot of blood of one or two lines 
in thickness. This clot was, in its turn, surrounded with cellu¬ 
lar tissue that crepitated between the fingers. All these gan¬ 
grenous portions communicated with the bronchial tubes. 
The right lobe was entirely changed into a deliquium of the 
colour of the lees of wine, and of an infectious odour, and in 
which it was impossible to truce any organization. The left ven-
