bodies, of which the diameter is less than half that of 
a coloured blood-corpuscle, are also seen in consider- 
iGaroe 
able numbers in the free state ;_ they possess a slightly 
greenish colour, and are perfectly homogeneous, differ- 
ing in both of these respects from nuclei of pus- 
corpuscles. When not enclosed in pus-corpuscles 
they occur either isolated or in couples ; in form they 
are usually spheroidal, but are occasionally oblong, 
showing a more or less marked constriction in the 
middle. Along with these, other forms exist, in 
which it can be made out that the body, if aspheroid, 
consists of a highly refractive smaller granule (micro- 
coccus) contained in a transparent envelope; or if 
oval or rod-like, of two such granules held together 
in a similar manner. Between these and the free 
micrococci to be immediately described, it is easy to 
observe the transition.- 
2. By the repeated division of the spheroids above de- 
scribed, the dumb-bells and necklaces shown in the 
figure! are formed ; the constituent micrococci of the 
necklaces are held together by a connecting transpa- 
rent substance. Sometimes they are all of the same 
size, but more frequently one is larger than the rest, 
and presents the appearance of a greenish transparent 
pear-shaped body, which may or may not contain a

bodies; this is not well shown in the engraving.
