CONTROLLING SEX IN BUTTERFLIES. 131 
replaced ten on a good supply of food, watched them carefully, 
and kept them eating until they attained a large size; they be- 
came chrysalides within a few hours of each other, and emerged 
as butterflies eight days after. One of these chrysalides was ac- 
cidentally crushed; the remaining nine were females. Of the 
starved ones, eight males came out; the remaining two chry- 
salides died. 
The butterflies, as fast as they made appearance, were killed 
and pinned up, the males arranged on one side, the females on the 
other —a most brilliant display, covering a much larger space 
than one would be apt to imagine. 
It would seem, then, as the result of the whole experiment, that 
sex is not determined in the egg of insects, and that the female 
requires more nourishment than the male. Nor does this appear 
strange, when we consider the reproductive nature of the female. 
It has frequently been said to me, “if your theory is true, it makes 
the female higher in the scale— superior to the male.” I believe 
it has always been admitted that the female gives birth to the 
young. If this is considered superiority, then the female is supe- 
rior; but if beauty of form and color is taken into account, then 
the male insect is superior, the same as with birds and the higher 
animals. Carry the analogy further—up to human beings — and 
still we find the principle holds good. To which sex belong all 
our great inventors, statesmen and philosophers? I believe | 
woman is physically incapable, other things being equal, off 
becoming as profound a philosopher, as deep a thinker, as man. 
I do not Wish it understood that I deem woman inferior to man ; 
there is no inferiority, no superiority. If this matter were better 
dead ; eight poor, starved-looking specimens were alive, and 
completed their transformations. With this butterfly it is difficult
