PHYSIOLOGICAL, PROTOPLASM AND THE CELL. Geil. Sub. 41 
Animal intelligence ; Weir (535). — Intelligence and instinct; Emery 
(149). — Limits of intelligence ; Morgan (362). 
Psychology of lizards ; Delbceuf (127) : of a snail ; Yung (557). 
Habits of Blennies ; Guitel, F. (200). 
Sociability and morality in animals ; Houssay (256). 
Industries of animals ; Houssay (255). 
Means of defence among animals ; Cuenot (115). 
Movements of animals from place to place ; Gunzel (198). 
Autotomy : The liabit was at first voluntary and intentional, duo to an 
instinct of self-preservation ; it was perfected, and became purely reflex; 
Fredericq (169). 
5. Protoplasm and the Cell. 
a. Protoplasm. 
Review of recent researches on protoplasm ; IIaswell (218). 
Structure of protoplasm : Historical account of observations ; 
D’Erlanger (153). — Structure of protoplasm and Altmann’s bioplasts ; 
Ceconi (93). — The Schaum plasma in reproductive cells of Branchipus. 
The apparent inter-relation between a foam structure and the phe- 
nomena of karyokiuesis ; Moore (358). 
Chemistry of living protoplasm : “ Theory of the specific individual 
capillary reactions of the protoplasm.” Uniqueness of protoplasm 
depends on capillary peculiarities. Destructive criticism of micellar, or 
tagma theory. Contrast between phytoplasma, which is especially the 
seat of synthetic ( Kondenscitions ) and reducing processes, and zooplasma, 
which is especially the seat of analytic and oxidising changes ; a contrast 
dependent on the possession of different capillary forces or colligative 
properties ; Wendt (540). 
Structure of plasma in blood corpuscles ; Griesbach (189). 
The granula theory of the structure of protoplasm ; Altmann (3). 
b. Cell Structure and Physiology . 
Summary and bibliography on cell-substance, archoplasm, centrosomes, 
nucleus, mitosis ; Flemming (162, 163). 
Structure of the cell ; Moore (357). 
General biological considerations ; van Bambeke (21), Virchow 
(515). 
Cell structure : — The indifferent cells of Hydroids represent a primi- 
tive condition, with a “Linen” framework, the mobile part, a granula, 
and the secretions, &c., of the granula. The granula consists of Zoa 
(simplest vital elements) and the “ Linen ” are Zoa united in rows. 
Interpretation of muscle-cells, nerve-cells, &c., in terms of the “ Linen ” 
and granula ; Schneider (461).
