tinguished at the first examination, but become extended 
after remaining at rest for a time under the microscope. 
The movement of the bodies is constant, slowly progressive, 
and apparently in a direction towards the light. The glo- 
bular bodies formed by processes of division are sometimes 
separated into two or more groups, each of which retains its 
own envelope of sarcode. When this has taken place the 
contours of the globular bodies become very irregular, and 
the bodies themselves are more widely separated. The whole 
of the creature is sometimes broken up into a number of 
isolated bodies, each of which is perfectly round, and fur- 
nished with its own layer of sarcode and with processes. 
Very long fine processes are sometimes thrown out from one 
body to another and connect the two. These isolated glo- 
bular bodies also undergo division processes. One of these, 
with included globules, and furnished with a long process, 
suspended by which the whole moves backwards and forwards 
like a pendulum, is represented by fig. 1. Some of the 
creatures here described undergo the following changes : — The 
processes are gradually retracted into the sarcode layer, a 
part of which is then elongated, and presents internally 
separated particles of the lining membrane enclosing isolated 
masses of green granules. The lining membrane is some- 
times lengthened in a pyriform shape and becomes distended 
near the small end, and presents there a vacuole-like vesicle. 
Finally, after death the elongated mass of sarcode breaks 
down into molecular matter, the enveloping membrane of the 
capsule retains its dark and distinct contour, the colourless 
granules are removed, and the green granules withdrawn 
from their original position near the perpihery.
