HEAT UPON LIVING MATTER. 7 
met with in abscesses and other situations, where 
pyemia or low typhoid states of the system exist, 
in the human subject. There were, in addition, a 
large number of ZYorula corpuscles, as well as of 
brownish nucleated spore-like bodies, gradually in- 
“credsing in size from mere specks, about zy3qqth up 
to gs/yath of an inch in diameter. Lastly, there was 
‘a small quantity of a mycelial Fungus filament, 
bearing short lateral branches, most of which were 
capped by a single spore-like body. (See Fig. 1.) 
Experiment IT. A strong infusion of common cress 
(Lepidium sativum), to which a few of the leaves and 
stalks of the plant were added, was inclosed in an 
hermetically-sealed flask in the same way, heated in 
the digester at the same time (and therefore to the 
same temperature), and was subsequently exposed to 
the influence of the same conditions as I have already 
mentioned in connection with the last experiment. 
This flask was, however, opened one week later—that 
is at the close of the ninth week after it had been 
heated in the digester to 270-275° F. Before break- 
ing the neck of the flask the inbending of the glass 
under the blowpipe flame showed that it was still 
hermetically sealed. The reaction of the fluid was 
found to be distinctly acid, though there was no 
notable odour. The fluid itself was tolerably clear 
and free from scum, but there was a dirty-looking
