nourishment of the mother and embryo, have presented a volume of reports 

which demand respectful consideration. The general report may be said to 

be the discovery that ABUNDANT NOURISHMENT DURING THE PERIOD OF SEXUAL 

NEUTRALITY TENDS TO PRODUCE FEMALES; WHILE LACK OF ABUNDANT NUTRITION 

DURING SUCH PERIOD TENDS TO PRODUCE MALES. 

 

These experiments, of course, have been chiefly performed upon the lower 

animals. The frog has been a favorite subject of such experiments--the 

tadpole stage being the one selected, because in that stage there exists 

a lack of sex, the stage being one of sex neutrality. Professor Yung's 

celebrated experiments will illustrate this class of experiments. Here 

were chosen 300 tadpoles, which when left to themselves manifested a 

ratio of 57 prospective females to 43 prospective males. These were 

divided into three classes of 100 tadpoles each. Each class was then fed 

upon one of several kinds of nutritious diet in order to ascertain the 

change in sex-tendency due to such food. The first set, with an original 

ratio of femaleness of 54 to 46, were fed abundantly on beef, and the 

ratio of femaleness was changed to 78 to 22. The second class, with a 

ratio of femaleness of 61 to 39, were fed on fish (specially nourishing 

to frogs), and the ratio changed to 81 to 19. The third class, with a 

ratio of 56 to 44, were fed upon a still more nutritious diet (i. e., 

that of frogs' flesh), and the ratio was raised to 92 to 8. In short, 

the experiments showed that the increase of nourishment in diet changed 

every two out of three male-tendency tadpoles into females. The 

experiment was held to prove that a rich diet, affording nourishment, 

during the period of sexual neutrality in the embryo, tended to develop 

femaleness. 

 

The advocates of this theory also point to the instance of the bees. 

With the bees, the larva of ordinary worker-bees are fed ordinary food, 

and do not develop sex; while the larva which is intended to produce the 

queen-bee is fed specially nutritious "royal food," and consequently 

develops larger size and full female sex powers. If the queen is killed, 

or dies, the hive of bees proceeds to produce a new queen by means of 

feeding a selected larva with the "royal food" and thus developing full 

femaleness in it. It is said by some authorities that in cases in which 

some other of the larva accidently receive, through mistake, crumbs of 

the "royal food," they, too, grow to an extraordinary size, and develop 

fertility. This fact is held by the advocates of the nutrition theory to
