XVIII. PROTOZOA. 
38 Prof, 
[1905] 
the same of environmental changes (culture-media, temperature etc.), 
Woodruff (507). 
Evidence against the general view that both ex-conjugants (in Para - 
moechim) are physiologically recuperated, Galkins (61). 
Observations on the (alleged) senile degeneration of various Infusoria 
( Glaucoma , Stylonichia and Vorticella spp.), Enriques (120 & 121). — 
Significance of the meganuclear fragmentation in Cryptochilum with regard 
to senile degeneration, Russo & di Mauro (389). 
Observation of the death and rapid dissolution of an Amoeba while 
apparently under normal conditions, Linton (266). 
1, Nutrition, excretion, osmosis, etc. 
On the physiology of nutrition in Protozoa ( Paramoecium y Stentor and 
Colpidium ) ; the formation of the food-vacuoles and the stages in digestion, 
Nirenstein (317). — Nutrition, digestion and defaecation in Amoeba do- 
jleini n. sp., Neresheimer (312). — Intracellular digestion in Paramoedum^ 
described, Metalnikoff (296). 
Researches on the mode of formation and operation, and the functional 
significance of the contractile vacuole, worked out on Glaucoma colpidium , 
Pegen (102), 
Production of carbon dioxide by Paramoedum , Barratt (12). 
Experiments and observations on respiration in Ciliates ( Paramoedum , 
Colpidium , Opalina etc.) ; Putter (367) finds that they can exist without 
free oxygen (under anaerobic conditions) for some time, particularly if well 
supplied with nutriment. 
Association of aerobic Bacteria apparently necessary for the successful 
development of the spores of Plasmodiopkora (of “cabbage-hernia”), 
Pinoy (350). 
Occurrence of fuchsinophilous grains, probably representing an internal 
secretion, in Cochliopodium , Faur6-Fremiet (130). — Presence of granules 
of barium sulphate in the new Rhizopods, Xenophyophora y Schulze & 
Thierfelder (432). — On a new pigment (zoopurpurin) of an Infusorian 
(. Blepharisma), Arciohovskij (5). 
On the powerful toxine (sarcocystin) produced by Sarcosporidia ; pro- 
bably, also, a haemolytic toxine is produced by malarial parasites, 
Blanchard (28). 
Experimental transformation of Vorticella microstoma into V. hians and 
vice-vers&, by a variation of the medium of cultivation ; a case of purely 
physiological adaptation, FaurIs-Fremiet (133). 
2. Locomotion. 
Four varieties of movement in unicellular beings (exs. Infusoria, 
Amoebce ) ; automatic, reflex, incoherent and voluntary, Abric (3). — 
Theoretical considerations regarding the physiology of protoplasmic and 
“ muscular” movements in Protozoa (chiefly Rhizopods), v. Knaut (212). — 
Theories of plasmic movement, as shown by Protozoa ; rejection of the 
surface-tension and coagulation theories, Schneider (415). 
Character of the movements in Amoeba described, Jennings (195). — De- 
velopment of his theory of movement in Amoebce by superficial tension, a 
theory which is largely or entirely mechanical, and which is quite different 
from Jennings’ conclusions on this subject, Rhumbler (376). — Remarks 
on the movements of Amoebce , Schouteden (417). — The manner of loco- 
motion in Amoeba terncola y Penard (335). 
Further considerations on the movements of Gregarines, Crawley (92). 
Physiological action of locomotor organellse (cilia and flagella), Schuberg 
(419).
