3io Ward. — Some Thames Bacteria. 
liquefying form, o *6 ju in diameter, associated in irregular 
glomeruli, and forming a pale rose pigment. 
Mention may also be made of M. agilis (Ali-Cohen 1 ), 
a motile form, i \x in diameter, and which sometimes liquefies 
slightly after a long time : a pink layer is formed on Agar 
and potato. 
In addition to the foregoing non-liquefying forms, may 
be mentioned a series which liquefy the gelatine : — Bumm’s 
Diplococcus roseus 2 , a liquefying air form ; Sarcina rosea 
(Schroeter 3 ), also a liquefying aerial form ; M. roseus (Eisen- 
berg 4 5 6 ), a slowly liquefying form found in sputum. 
Sarcina mobilis 5 (Maurea), said to be motile (?), liquefies, 
and will not develop on potato. 
Finally, reference may be made to Bacillus prodigiosus , 
which is often termed Micrococcus prodigiosus , owing to the 
shortness of its rodlets : this seems identical with M. haema- 
todes described by Zopf G as the form concerned in bloody 
sweat. 
The resemblances to Zimmermann’s M. carneus , which he 
regards as probably identical with Maschek’s form 7 , is so 
marked that only one point of importance indicates lack of 
identity. This is as regards the mode of division. Zimmer- 
mann says (1. c. p. 78) the divisions occur in one direction 
only, but I find the divisions occur in all directions, and that 
in certain stages the groups resemble a Sarcina. It is an 
interesting point that Maschek’s form (I quote from Lustig, 
1 . c., p. 40) presents the same similarity to a Sarcina that mine 
does, and we have seen that Zimmermann regards Maschek’s
