SUPPURATIVE LARYNGITIS. 
pus highly charged with remnants of the destroyed tissue, 
with sloughy unhealthy-looking parietes, never bounded by a 
true wall, or sound plastic lymph in process of organization. 
In the lungs the true metastatic collections of pus are often 
fetid, of a dark green or brown coffee colour. Such abscesses 
are readily obtained in the viscera, suppurations also oc- 
curring in the joints, when pus is injected into the aorta of 
a horse, dog, or other animal ; and may be seen after injecting 
the jugulars too, if repeated introductions of pus into the 
venous system, at short intervals, are effected. 
If all instances of multiple abscesses within the body, with 
the exception of true glanders, are to be classed under the same 
head, it appears undoubted by this case, by no means a solitary 
one, that a distinction must be drawn between traumatic and 
idiopathic pyaemia. My brother, in 1853, defended the opinion 
of the occurrence of abscesses, in various parts of the body, not 
traceable in their origin to pus carried through the blood from a 
suppurating wound, or formed in an inflamed vein. 
The idiopathic pyaemia of my brother is clearly the pyogenic 
fever of Dr. Jenner. The Gulstnian Lectures, that were 
delivered by the latter gentleman, and published in the 
Medical Times and Gazette for 1833, contain a very inter- 
esting account of this acute purulent diathesis ox pyogenic fever ; 
and as I think that to it may be referred Mr. Vincent’s case 
of abscess in the cerebrum,* your case of metastatic abscesses, 
and many of those instances of internal suppurations in 
strangles, I shall transcribe some most important sentences 
from Dr. Jenner’s lecture. 
“ Immediately after the termination of the acute specific 
diseases,” the Doctor tells us, (i it is by no means uncommon 
for one or two small abscesses to form in the subcutaneous 
cellular tissue.” 
“ These disseminated abscesses in the subcutaneous tissue, 
after or during the progress of the acute specific diseases, are 
allowed pretty generally to have their origin in a diseased 
condition of the blood ; only by some they are held to be 
critical, the evacuants of peccant matter ; while by others 
they are regarded merely as local inflammations, excited by a 
diseased condition of the blood.” 
‘‘The idea that these subcutaneous collections of purulent- 
looking fluid of small size, and the formation of which is 
attended with little constitutional disturbance, are due to any 
foreign solid matter, be it pus-globules or any other, circu- 
lating in the blood, has never, so far as I know, been ad- 
vanced ; it would be too untenable to be entertained for an
