The phenomena of plumage inheritance in canaries are held by the author to 
be generally in accord with Mendelian principles. 
(11) Davenport, G. 0. and Davenport, C. B. Heredity of Eye Colour in Man. Science, N. S., 
Vol. XXVI, pp. 589—592. 1907. 
Discussion from Mendelian stand -point of the statistics of eye colour in 132 indi- 
viduals, with their ancestry. " Blue is recessive to gray and gray is recessive to 
brown."

Same material as is used in above-mentioned eye colour study. "All results 
indicate with a high degree of probability that straight hair is recessive to spiral 
hair." In some cases spiral may fail to dominate.

there is no homogamy, but the methods used to determine this are entirely in- 
adequate. No correlation coefiicients were calculated.
