II. MACROSCOPIC CHARACTERS OF STRAINS OF S. CARNIS. 
The strains were cultivated on various media of which Dox’s 
agar (containing half the usual amount of sugar), Sabouraud’s 
glucose agar, and potato chunks were selected as best. On these 
media, especially on the second, the various strains, even when 
young, show marked differences. All are more or less white 
when young, but some show a peculiar yellow or orange dis- 
colouration inside the medium, which is absent from others. 
When the colonies are old, the aerial portions differ greatly in 
colour, varying in different strains from white to brown. Some 
strains are considerably more woolly in culture than others, 
especially on potato chunks. 
III. PHYSIOLOGICAL CHARACTERS (S. CARNIS). 
(a) Chemical. The various isolations were grown in 4 % solu- 
tions of sugar to which peptone and litmus had been added.

They showed no great differences in their fermentation pro- 
perties, all fermenting glucose, maltose, and laevulose, though ~ 
the amount of acid produced varied to some extent. One or 
two forms also fermented sucrose. Some forms, especially those 
which showed a yellow discolouration of ordinary media, pro- 
duced a yellow or orange pigment which diffused through the 
liquid. Three forms produced a dark-brown pigment instead of 
a yellow, and in one the litmus was bleached when the cultures 
were kept a month.
