delized are finally so fixed that they blend with 

 the older structure of heredity and no longer 

 present the phenomena of "dominance" and 

 "recessiveness" — in a word, that heredity is a 

 somewhat larger term than Mendelism, and that 

 the biologist or botanist or plant developer who 

 would gain a really clear conception of the situ- 

 ation must clearly distinguish between the lesser 

 term and the greater, although at the same time 

 recognizing that one is an essential substructure 

 of the other. 



So Darwinian heredity, which recognizes the 

 heritability of whole coteries of characters that 

 are too profoundly fixed to Mendelize, is again 

 receiving recognition; and the multitude of spe- 

 cial studies of the past decade that were inspired 

 by the rediscovery of Mendel's work and by the 

 exploitation of his formula will take their place 

 as interesting additions to the minutiae of the 

 scheme of heredity, without being supposed by 

 anyone, except here and there a victim of mental 

 strabismus, to represent the full measure of the 

 great mysteries of inheritance. 



We have had occasion in successive chapters 

 to present again and again illustrations of the 

 type of hereditary transmission that lends itself 

 to classification under the Mendelian notation. 

 We shall catch further glimpses of it before we
