a very thin layer. The bright orange-red. colour of the 
Avhole halls was apparently chiefly caused by the orange-red 
and rather strongly shining granules. 
The chemical examination of the pale reddish yellow 
structureless body substance soon showed it to be of an 
albuminous nature. It showed the same reactions which 
are presented in a similar manner by the plasma or proto- 
plasma of Cytodiae, and the cells of animals, protozoa and 
plants. Carmine coloured the whole mass dark red, iodine 
dark brown. Mineral acids produced a granular coagula- 
tion. Nitric acid coloured the plasma dark yellowish brown ; 
sulphuric acid, verdigris-green. The last reaction reminded 
me of the similar colouring of the pigments of the Aeantho- 
metra by sulphuric acid. The larger as well as the smaller 
granules in the structureless ground substance were not 
affected by potash, while the plasma slowly dissolved in it. 
There was not the slightest trace of any differentiation or 
structure in the empty exuded plasma. 
The further developed balls which contained a great quan- 
tity of little orange-red bodies, instead of the large, homoge- 
neous plasma-ball, were also tolerably easy to burst. Their 
structureless envelope, however, was somewhat harder and 
more consistent. The orange-red contents which exuded 
from the burst envelope separated in water into single par- 
ticles, which were easily separated from each other. The 
single balls were all of the same size, of 0017 mm. diameter. 
They were entirely naked and uncovered, formed simply 
and solely of the reddish yellow plasma, in which were sus- 
pended a quantity of very fine and small shining orange- 
red particles. The larger reddish yellow and red globular 
granules, which were dispersed through the plasma of the 
undivided balls, were entirely absent here. They were also 
wanting, too, in those balls in which the furrows on the 
surface showed the commencement of the separation of the 
plasma into smaller balls. There was as little trace of a 
nucleus or of a contractile vesicle in the small balls as in 
the large undivided balls. 
The small orange-red balls, which were apparently pro- 
duced by the division of the one large plasma ball, showed 
no movement during my first examination. Instead of this, 
amoeba-like motions soon afterwards commenced in one of 
the large undivided orange-red balls, which I had with 
great care freed from their structureless envelope, not by 
bursting them under the microscope by the pressure of the 
covering-glass, but by piercing and tearing them with two 
pointed needles in a watch-glass with sea water. How-
