penetrated at all sides by the iodine does it acquire a slightly 
yellow appearance, which, however, upon being removed by 
blotting paper, and water added, again disappears. Only 
under persistent action (of the iodine) does the capsule 
become tinged a light yellow, retaining, however, its pellucid 
glassy appearance. 
“From all this ” (urges the author) “it follows that as 
regards the problematic hyaline outer border in Amphizonella 
it is not a protoplasma-layer appertaining to the rhizopod- 
body, but we have really to do with a comparatively thick 
‘capsule,’ bounded off and essentially distinct therefrom. 
** As regards the body-mass included by this capsule,” (the 
author goes onto say,) “this is permeated by amostly dark violet 
pigment, frequently, however, it assumes a trace of yellow or 
brown, and this again depends upon a second pigment 
diffusely distributed in the body, which, under circumstances 
hereafter to be mentioned, sometimes presents itself exteriorly. 
Under natural conditions, and without pressure on the 
covering-glass, little can mostly be made out as to the 
contents owing to the darkness of the colour, with exception 
of the vacuoles, always existent in considerable numbers, but 
minute, as well as a large round body (nucleus), which 
structures make themselves evident from within, by their 
somewhat clearer appearance. The violet colouring substance 
is, however, very sensitive, and readily destroyed by the 
gentle action of acids, alkalies, alcohol, iodine, &c., and then 
the contents, having become considerably clearer, can be 
examined. Sometimes compression succeeds in extruding 
and isolating, uninjured, the contents and the most important 
parts. Amongst the varied kinds of food expelled (Diatoms, 
Arcelle, Euglyphe, &c.), a large round body, the ‘ nucleus,’ 
at once strikes the eye. This measures about 0.04mm. in 
diameter, and has a rather soft consistence. It resembles 
in structure that of Ameeba.” [The author here adduces that 
of his A. terricola, previously described by him; a perfectly 
hyaline investment surrounds a space, which is completely 
filled with round solid granules, and the author has every 
reason to suppose that the progress of development of these 
granules is essentially the same as in Ameba terricola, 
although he has not yet been successful in observing the 
transitional forms. The author here alludes to a breaking 
up of the nucleus and scattering around of the granules, each 
one the germ of a young Ameba, by successive stages, 
putting on the character of the mature form— see the 
preceding portion of this memoir on Ameba terricolal.
