into the abdominal cavity; or, better still, by the injection of fil- 
tered serum from animals which have recently succumbed to an ex- 
perimental inoculation (one cubic centimetre repeated daily for seven 
or eight days). 
BACILLUS CADAVERIS. 
Obtained by the writer (1839) from pieces of liver and kidney, from yel- 
low-fever cadavers, which had been preserved for forty-eight hours in an 
antiseptic wrapping, at the summer temperature of Havana; also in two

cases from pieces of yellow-fever liver immediately after the autopsy; also 
from liver preserved in an antiseptic wrapping from comparative autopsies 
made in Baltimore. 
Morphology.—Large bacilli with 
square or slightly rounded corners, 
from 1.5 to 4“ in length and about 
1.2 » broad; frequently associated in 
pairs; may grow out into straight or 
slightly curved filaments of from 5 
to 15 » in length. 
Biological Characters.—An an- 
aérobic, non-motile bacillus; not 
cultivated in nutrient gelatin; not 
observed to form spores. 
Bacillus cadaveris is a strict anaé- 
robic and is difficult to cultivate. I 
have succeeded best with nutrient 
agar containing five per cent of 
glycerin, removing the oxygen 
thoroughly by passing a stream of 
hydrogen through the liquefied me- 
dium. The colonies in a glycerin-
