EVOLUTION. 
Gen. Sub. 55 
as regards the formation of red-blood corpuscles ; Kronecker & Marti 
(417). 
Influence of environment, Kunstler (421). — Influence of gravity; Loeb 
( 447). — Influence of light; Loeb (447). — Influence of heat and light on 
cleavage; Mead (489). 
Modifications in species of Etheostoma; Moenkhaus (513). — Effects 
of temperature and light on frog’s eggs; Morgan, T. H. (522). — Influence 
of reagents— salt, creosote, nicotine, cocaine, etc. — on bivalves; PiIsri 
( 567). — Influence of a constant electric current on Amoebae; Schenck 
( 645). — Variations and modifications in freshwater Crustacea ; Stingelin 
( 684). — Action of heat and cold on chrysalids of Vanessa; Urech (719). — 
Relation of respiratory exchange and temperature in cold-blooded animals ; 
Vernon (725). — Relation between the form of the cell and the meta- 
bolism; Verworn (731). — The laboratory of the catacombs; ViRlt (739). 
Influence of solutions of various concentrations on Infusoria : Yasuda 
(779). 
Accommodation defined as functional adaptation of the individual 
organism to its environment, which may result in a ‘modification.’ [More 
simply = an adaptive reaction (?)]; Baldwin (19). — Modification defined 
as change of structure or function due to accommodation ; Lloyd Morgan 
(520), Baldwin (19). 
d. Selection and Isolation . 
Dutch edition of “Darwinism and Race Progress”; Haycraft (323). 
So-called “organic selection”: the perpetuation and development of 
congenital coincident variations in consequence of accommodation ; Bald- 
win (19). 
Orthoplasy : the directive or determining influence of organic selection 
in evolution. [But the term seems to have a wider connotation] : Baldwin 
(19). 
Possible origin of a new character without any selection ; Emery (182). 
— Germinal selection may originate new characters independently of 
individual selection; Emery (182). — Different degrees of severity in 
selection, corresponding rate of racial change; Galton (252). — Scope of 
natural selection ; Graham (290), Henslow (336). — Origin of species and 
breeds; Kohlwey (408). — So-called organic selection; Lloyd Morgan 
( 520). — Limits of organic selection ; Osborn (543). — Selection ; Pearson 
(553). 
. Utility of specific characters: — The value of specific characters; 
Cockerell (123-125). — Gulick (302). — Utility of specific characters in 
Decapod Crustacea; Garstang (258-260). — All organic structure is not 
adaptive; much is quite indifferent; Emery (182). — Problem of utility; 
Hutton (362). — Non-utilitarian character of many features in colouration 
of insects ; von Wattenwyl (755). 
Struggle : — 
Function of disease in the struggle for existence; Cockerell (126). — 
Displacement of species in New Zealand; Kirk (393). — Blindness of 
animals in darkness ; selection of those which are better able to do with 
deficient food, so deficient that the eyes degenerate ; von Lendenfeld (439). 
Numerical proportions of species, considered in relation to parasites 
among insects ; Marchal (472). — Protective mimicry as evidence for the 
validity of the theory of natural selection ; Poulton (579). 
Isolation: — Vol. hi, Darwin and after Darwin; Romanes (616). 
Isolation in organic evolution; a posthumous essay; Romanes (619). — 
The place of isolation in evolution ; Hutton (363). 
Reproductive divergence, an additional factor in evolution: Vernon 
(726 & 727), Jordan (378).
