1. GENERAL SUBJECTS. 
b. Heredity. 
General notes on and discussion of heredity ; Andriezen (9), Lloyd 
Morgan (374), Orciiansky (393), Ribbert (457), ELeckel (211). 
Present problems in evolution and heredity ; Osborn (396, 397). 
What are acquired characters ? Discussion by Fry, Poulton, Lan- 
kester, Galton, Cunningham : see Fry (175). 
Inheritance of acquired characters ; Haacice (207). 
Inheritance of acquired characters : According to Haacke, the facts 
proving the inheritance of acquired characters are as abundant as the 
“ sand on the shore,” but von Lendenfeld observes that not a grain is in 
evidence ; Lendenfeld (303). 
Case of inheritance of acquired character ; Hill (241). — Inheritance of 
effects of squatting posture ; Charles (87). — Cases from Lepidoptera in 
favour of Neo-Lamarckism ; Packard (402) : in cave animals; Packard 
(403). 
Inheritance of diseases and abnormalities ; Hanau (219). 
Possibility of inheritance of acquired characters ; Klebs (275), 
Ornstein (394). 
Acquired characters only transmissible when they presuppose a definite 
predisposition. A somatogenic adaptation is the outcrop of latent quali- 
ties ; Reii (443). 
Phylogeny of an acquired character : Cumulative results (from study 
of Cephalopod shells) are held as supporting a Neo-Lamarckian theory ; 
Hyatt (154). 
Criticism of alleged transmission of mutilations ; vom Rath (441). 
Heredity optic-nerve atrophy : “ A peculiar physical condition which 
has been obtained from frequently repeated physiological acts during the 
life of some antecedent form may be transmitted ” ; Oliver (392). 
Mechanism of heredity to be discovered by a study of the conditions 
of growth, the mechanisms and correlations of the same, and not by onto- 
genetic theories of gemmules and the like ; Ryder (475). 
Continuity between genital cord of parent and that of bud in Com- 
pound Ascidians ; Pizon (421). 
Variations in chromosomes show that one must be careful not to 
exaggerate the exactness with which these represent the hereditary 
material ; Herla (233). 
Sexually-produced organisms without maternal characters ; Seeliger 
(505). 
Regeneration, facts of, requiring to be considered in connection with 
heredity in Turbellarians ; Keller (265, 266), Voigt (550). 
Transmission of immunity ; Charrin & Gley (88). 
Discussion of theory that “ the phenomena of recapitulation, character- 
istic of ontogeny, are due to the presence of a record in the germ-cells, 
having a molecular basis similar to that of memory " ; Cope (99). 
“ Anlagen,” the existence of ; Mitchell (359). 
Criticism of germ-plasm theory ; Pfeffer (416). 
Heredity and longevity ; Lebon (298).
