STUDIES AMONGST AMCEB.E.

there was a narrowing, then a little neck and a round globular 
head covered with very minute, short, hair-like processes. This 
was something quite new, and it was very exciting to observe 
the curious movement of the body and the comparative steadi- 
ness of the curious neck and head. The diaphane was scanty 
near the head, but abundant at the opposite or forward-mov- 
iug end ; and the endosarc, dense, granular, and nearly opaque 
at the head and neck, became more diffluent elsewhere. 
The endosarc was in wonderfully active movement, pouring’ 
down the axis of the sausage-shaped thing, streaming out into 
the diaphane as it altered its shape, and approaching the very 
edge with active motion ; then it turned backwards on all sides, 
so that a counter current occurred near the whole surface, the 
granules moving then towards the head. Then they entered 
the axis again, and could be followed about here and there until 
they got into the stream and rejected their former path. 
No pseudopodia of any size came forth ; but there was a lobular 
projection, first on one side of the forward-moving end and then 
on the other (fig. 38), the one being overwhelmed by the other 
as general movement progressed. Two or three small angular 
pseudopodia came out, and remained not far from the neck. 
Under a one-eighth inch object-glass the motion of the contents 
of the endosarc was very curious, and a good deal of it was 
independent of the contraction and dilatation of the diaphane 
and endosarcal protoplasm. The movements of the proto- 
plasm produced great currents, but there was something going 
on like that movement which can be usually seen in the ends of 
the crescent-shaped green Closterium. As the Amoeba moved 
along nothing got into it; and an animalcule came at full 
speed against its sides, but made no impression. After a while a 
change of shape occurred, the cylindrical form gradually merged 
into the hand-shaped (fig. 40), the head and neck still retaining 
their size and position at the end remote from forward move- 
ment. As the body flattened out, the nucleus became visible, 
and the contractile vesicle more distinct close to the junc- 
tion of the head and neck. The minute long pimples, like 
stumpy hairs on the globular head, move, but do not increase 
in size except in length. I did not see auy food taken in, and 
indeed the creature was pretty full ; but after it had been in 
open water for an hour or so, it began to be uneasy and to move, 
wide end in advance, first on one side and then on the other, as 
if seeking for something to eat or move amongst, and finally it 
disappeared under some conferva. 
The next of this kind I saw feeding. The creature came out 
of a mass of vegetation with a bundle of minute things sticking' 
to its head, and it dragged its load about until finally something' 
stopped the way and the head made its appearance. There was
