Gaule, J. Bedeutung der Cytozoen. Biol. Ceutralbl. vi, pp. 345-351 ; 
Tag. Deut. Nat. Yers. 1885. 
These elements not simply parasitic, but unite the constituents of 
other tissues, and, as fundamental elements, afford a key to understand- 
ing of organic structure. 
Geddes, P. Theory of Growth, Reproduction, Sex, and Heredity. 
P. R. Soc. Edinb. pp. 911-931. 
The Protozoa are essentially protosperms and protova, exhibiting in 
their lines of differentiation and life-histories the outcome of preponder- 
ant or equated anabolism and katabolism, and in their incipient dimor- 
phism the primitive expression and fundamental secret of sexual diffe- 
rences.

Gruber, A. Der Conjugationsprocess .bei Paramceeium aurelia. Ber. 
Ges. Freib. i ; Ann. N. H. xviii (1886), pp. 164 & 165. 
In Paramceeium aurelia the conjugation is associated with intermix- 
ture of nuclear substance ; the nucleoli also come together. 
. Mittheilungen iiber Protozoen Studien. Ber. Ges. Freib. i, 
Heft 2 ; Ann. N. H. xvii, pp. 473-494. 
Physiology of Protozoa , especially Stentor cceruleus. Regeneration due 
to conversion of elemental parts by external irritation. The nucleus an 
essential species-preservative constituent. Spontaneous division, either 
at limit of growth, or in rapid succession with decrease of size in un- 
favourable conditions. The two daughter individuals not absolutely 
congruent. Diffuse nervosity, chiefly in cortex ; a single thread-like 
bridge of protoplasm, enough to cause a conjugating pair to make con- 
cordant movements. 
. Die Frage nach dem Bestehen verschiedener Plasmaschichten im 
Weichkorper der Rhizopoden. Biol. Centralbl. vi (1886), pp. 5-8. 
The protoplasmic layers of Rhizopods are the artificial results of stain- 
ing, or due to temporary aggregation of granules and vacuoles. Homo-
