hemolytic and nonhemolytic strains by the superficial streak 
method on blood agar plate followed by differentiation by the 
use of sugar media: lactose, mannite, and salicin. 
To simplify our work we followed the last-mentioned classifi- 
cation. I will give now a preliminary report of the results of 
our investigation and will reserve the technical part of the 
work for a later publication when I hope to be able to report 
the results of investigations covering a greater number of cases 
than at present. We made bacteriological examination of the 
secretion from the cervix uteri and posterior cul-de-sac in every 
patient, before and after delivery. Doderlein’s classification of 
vaginal secretion was not made. In a series of eighty cases 
examined, antepartum and postpartum, the results are as follows : 
Bacterial findings in the eighty cases examined anterpartum. 
Cases. 
Hemolytic streptococcus 15 
Nonhemolytic streptococcus 3 
Bacteria other than streptococcus 53 
Sterile 9 
Results as to distribution of bacteria in the eighty cases examined 
antepartum. 
Cervix : Cases. 
Hemolytic streptococcus 12 
Nonhemolytic streptococcus 3 
Bacteria other than streptococcus 39 
Sterile 26 
Vagina (posterior cul-de-sac) : 
Hemolytic streptococcus 15 
Nonhemolytic streptococcus 3 
Bacteria other than streptococcus 53 
Sterile 9 
Bacterial findings in the same eighty cases postpartum. 
Cases. 
Hemolytic streptococcus 20 
Nonhemolytic streptococcus 10 
Bacteria other than streptococcus 47 
Sterile 3
