what appeared allowable to be regarded as such, were still 
destitute of the above described hyaline outer coat, were still 
naked, as if it appeared those were developed only at a 
certain stage ; these conditions demand a closer investigation. 
‘The movements of this creature,’ (says the author), 
‘are peculiar,—the contractions and modifications of form of 
the whole body take place exceedingly sluggishly, and the 
form must be observed carefully and persistently in order to 
make one’s self certain about them. These consist ordinarily 
of only slight undulate projections from the circumference of 
the body, the roundish form of which only exceptionally 
passes over into an oval. In all these general movements 
of the body the outer capsule takes a constant, if, indeed, 
only a secondary part, in that it readily yields to every 
impulse outwards of the inner body. 
“The movements of the sword- or finger-like pseudopodia, 
projected from the interior, evince themselves differently. 
These project forth with a perfectly hyaline blunt apex, 
pushing on in advance only a simple contour, never (according 
to the author’s observation) the double contour of the outer 
coat, thus proving that the latter becomes perforated with 
readiness by the inserting of the cuneate process.” [The 
author adds that] “‘ This fact is confirmed by the circumstance 
that the pseudopodium can be frequently followed through 
the outer capsule down to its basis, that is to say, to its 
origin in the interior of the body-mass. Ordinarily, the 
pseudopodia do not extend outwards beyond a certain limit, 
remaining hyaline throughout the whole length; however, 
if they become more elongated, which rarely happens, then 
a dark and coarsely granular substance streams forth from 
the interior into them, not, however, pressing on further than 
about half-length. Their motions are much more vigorous 
than those of the body in general; they usually come forth 
rapidly, but only when the creature has been permitted to 
remain for some time at rest and undisturbed, disappearing 
again just as quickly upon any jar. 
“If we revert to the outer capsule, we find it showing 
wonderful peculiarities—on the one hand an extraordinary 
resistance to outer influences (as before detailed) and on the 
other hand, as it appears, a soft and gelatinous consistence, 
readily permitting the penetration of the pseudopodia, and, 
without doubt, after their retraction, fillmg up the openings 
produced in the substance by fusion at those places.” 
[Touching the latter point, that is the ready fusibility of the 
substance of the capsule, the author next communicates a 
peculiar observation, one at the same time of further interest. ]
