THE AMERICAN SOCIETY OF BACTERIOL- 
OGISTS. 
TuE American Society of Bacteriologists 
held its second annual meeting at Baltimore, 
at the end of December under the presidency 
of Professor Wm. T. Sedgwick, whose ad- 
dress has already been published in Scrence. 
The following papers were presented : 
Distribution of Bacillus wrogenes capsulatus: 
W. H. WeEtc#. 
Dr. William H. Welch presented the re- 
sults of investigations of Mr. L, K. Hirsh- 
berg in the Pathological Laboratory of the 
Johns Hopkins University. There can be 
no question but that the bacillus discovered 
by Welch in 1891 and fully described by 
Welch and Nuttall in the following year is 
identical with Fraenkel’s B. phlegmones em- 
physematose, with Veillon and Zuber’s B. 
perfringens, and with Schattenfroh and 
Grassberger’s Giranulobacillus sacchwrobuty- 
ricus ummobiles liquefaciens described in 1900. 
It is possible that Klein had in his cultures 
B. erogenes capsulatus, but his description of 
his B. enteritidis sporogenes can not be recon- 
ciled with the properties of the former bacil- 
lus, especially his statements as to motility 
and peptonization of milk. It has already 
been demonstrated by Welch, by Howard, 
and by Hitschmann and Lindenthal that 
B. erogenes capsulatus is a widely distributed 
organism, its natural habitats being espe- 
cially the intestinal canals of man, animals
