several different sores without any appearance of blood 
escaping, or the person having the slightest- pain ; affording 
a sufficient proof of the canals being formed in the coagu- 
lated pus immediately on its coagulation, before any other 
approximation to living animal solids had taken place. 
The readiness with which the blood displaces the carbonic 
acid gas contained in these canals, may be explained by the 
great disposition the blood has to absorb this particular gas, 
which forms so large a proportion of its component parts. 
I shall not take up the time of the Society with a farther 
detail of experiments, although many more were made, as 
the results were uniformly the same. 
If I have succeeded in establishing the object of this Lecture, 
which is, that the coagulated pus is rendered tubular by the 
extrication of its carbonic acid gas, and that these tubes or 
canals are immediately filled with red blood, and thus con- 
nected with the general circulation, there will be little diffi- 
culty in making out the succeeding changes, by means of 
which the coagulated pus afterwards becomes organized ; 
since Mr. Bauer’s drawings, laid before the Society last year, 
trace the thin covering of the canals in the coagulated blood 
to the thick arterial coats met with in the testicle after the 
coagulum had remained a month in that situation ; and it is 
the arteries which build up all the different structures in the 
body, as well in the restoration of parts, as in their original 
formation. 
The farther prosecution of this enquiry belongs to the 
science of Surgery ; but as the explanation which I have given 
of the process employed in the regeneration of parts is, I
