Prot. 21 
Greenwood (78) studies the process of digestion in Oarchesium poly- 
pinum , notirig that this action may take place at any point throughout 
a relatively large part of the central substance; but the region of ejection 
is, like that of ingestion, definite. 
Kanthack & Hardy (109) discuss and compare the processes observed 
in the Protozoan and endodermal cell of the Metazoa , resulting in the 
capture, ingestion, and absorption of food-materials. 
Le Dantec (128) studies the method of nutrition in Gromia Rnd 
A nucha. 
Le Dantec (130) holds that an Amaiha completely spread out adheres 
by molecular attraction. 
Lindner (136) discusses an example of a stalkless parasitic Vorticella. 
Ludloff (142) discusses the effect of electric currents upon the 
Faramo&cia, 
Lunri (143), following Schewiakoff, believes the movement of Gregarines, 
like that of the Diatomacese, to be due to the propulsion of excretions 
from the body of the Protozoon. 
Mendelsohn (150) describes experiments showing that Paranicccia &r6 
negatively thermotropic to temperatures above 28° C., and positively 
thermotropic to temperatures below 24° C. 
Zacharias (227) continues his researches bearing on the periodic dis- 
tribution of the Plankton fauna of Plon. 
4. Methods of Preservation and Preparation, 
Celli & Fiocca (27) find that Anuchcb aro roadily cultivated on Fucas 
crispu8. 
Hornell (97) describes Formalin as a preservative medium for Protozoa. 
5. Distribution, 
a. Hosts and Seats of Protozoa. 
1. Protozoa (generally). 
For their rflle in Human and Animal Pathology generally, soo Braun 
(13), Gabritsciiewsky (76), Hauser (91), who discusses in detail the 
relation of the Protozoa to malaria, the pebune in silkworms and tumours ; 
Miller (151), in relation to cancer; Pfeiffer (171-173), Pick (174), 
Sicciardi (202), Winogradsky (222), in nitrification; and Zune (229). 
2. Amceba. 
BerndT (7), in abscess of liver ; Capitanio (21), Celli & Fiocca 
(25-27), in human intestine and vagina ; Moniez (155), and Vivaldi (218)^ 
A. colt: Casagrandi & Barbagallo-Rapisardi (23), and Harris (88). 
3. SporOzoa. 
ClarkE* J. J. (34, 37), Spennatobinm in OligochM ; Eisen (61), in 
birds and man; Mingazzini (153), in carcinoma, &c. ; SawtsciienKo (187); 
4. Gregarinidea. ' 
lu vaccine lymph, Ogata (164).
