Stout: A Graft-Chimera in the Apple 
the sector of King are pure for King; 
those arising from the part that is 
Russet are pure for that variety, and 
those that happen to arise from the 
line of contact continue to be sectoral 
chimeras. It is possible that in some 
of the branches the two kinds of tissue 
237 
are in periclinal relationship and that 
some fruits possess a skin of one 
variety and a core or body of the other. 
Rather careful examination of a large 
number of fruits by one competent to 
judge the flavor would be necessary to 
determine this point. 
A French Student of the Birth-Rate 
La Narairé, par Gaston Rageot, 
professéur agrégé de philosophie. 
Pp. 296, prix f. 5.75. Paris, Biblio- 
theque de philosophie scientifique, 
Ernest Flammarion, editeur, 1918. 
After discussing with clarity and 
relentless logic the various conceptions 
of the population problem that are 
current, Professor Rageot outlines ways 
in which he believes the French birth- 
rate can be increased. They are mostly 
in the direction of making family life a 
more prized privilege, either by edu- 
cation (creation of public sentiment), 
economic changes (e.g., inheritance of 
land), or political changes (less military 
service for fathers, extension of suffrage 
to women), and the like. While the 
constructive proposals contain nothing 
particularly new, the book as a whole 
is one of the most brilliant and pene- 
trating studies of the birth-rate that 
has ever been published.—P. P. 
Eugenics Made Easy 
Tue RacrtaL Prospect, by Seth K. 
Humphrey. Pp. 261, price $2. New 
York, Charles Scribner’s Sons, 1920. 
Mr. Humphrey has rewritten his 
book ‘‘Mankind,” reviewed in the 
Journal of Heredity in November, 1917, 
and has made of it an unusually suc- 
cessful presentation of the essentials of 
eugenics in the simplest terms. He 
offers no statistics, no pedigree-charts; 
instead he gives his readers the elemen- 
tary, yet vigorous and epigrammatic 
kind of writing that one expects to find 
in a newspaper editorial. It is a diffi- 
cult job to do well, but on the whole 
Mr. Humphrey has done it well; and 
it is worth while to have the problems 
of eugenics stated, for once at least, in 
kindergarten form. 
The author realizes that mere state- 
ment of the problem will not solve it; 
but his own solution is not up to the 
level of the rest of the book. In the 
last chapter he takes a look forward to 
the time when the lower 5% of the 
population will be segregated or steril- 
ized, while the hundreds of thousands 
of superior celibate women will become 
mothers by virtue of a state-organized 
system of artificial insemination. This 
sort of patent-medicine cure for the ills 
of society is not what will make eugen- 
ics prevail, and it is a pity that Mr. 
Humphrey, realist as he is, can not 
appreciate that human progress does 
not come by such simple expedients. 
The eugenic welfare of a nation is 
bound up with almost every manifes- 
tation of the nation’s activity; and by 
hurdling over this fact Mr. Humphrey 
has fallen short of producing a book 
that could be commended without 
reservations.—P. P.
