nation, or conservative adaptation, due to continued persistence under

in successive chapters : adaptation ; acquired characters ; disuse of 
organs, degeneration, and panmixia ; the acquisition and inheritance of 
intellectual characteristics ; the development of organs and systems j the 
laws of growth.

(1) History of theories of variation ; (2) theory of natural selection ; 
(3) corroborations, controversies, and accessory hypotheses ; (4) laws of 
variation — the influence of the environment, use and disuse, correlated 
variations, recent opinions, and the author’s own theory. “ Briefly 
stated, the view of evolution reached is that of definite variation, with 
progress essentially through the subordination of individual struggle and 
development to species-maintaining ends.” This is illustrated in the 
arrest of vegetation by reproduction — in the origin of the flower, of 
shortened inflorescences, of hypogyny, of angiosperms, of grassy and 
orchid-liko types, &c. “What we call higher or lower species or orders 
are the loaders or the laggards along ono or other of these two lines of 
variation, the representatives of some stage of the predominance on one 
side of that oscillating balance between vegetative and reproductive 
processes which have long been known as the essential functions of 
organic life.” Among animals the types of Protozoa are “not the 
' empirically selected products of spontaneous variation among indefinite 
possibilities, but simply the predominatingly amoeboid, encysted, and 
motile phases of the primeval cell-cycle, these three forms of which are 
fixed by the properties of protoplasm itself, each particular phase being 
fixed by the constitutional bias (diathesis) of its type towards anabolism 
or katabolism.” “The greatest of all steps in morphological progress, 
that from the Protozoa to the Metazoa , is not due to the selection of the 
more individuated and highly-adapted forms, but to the union of rela*
