Abstract: A review of recent literature concerning the germ
P=8.sma of the sexual cells of different types of animals, with
special emphasis on studies aiming at the modification of the
primary sexual cells. The studies involved injections of desoxi-
ribonucleiC acid in chicks; injections of ribonucleic and dea-
oxyribonucleic acid in chick embryos;'and blood injections.
Includes 6 figures and one table.
