uestion has been asked in
all ages of the world. Many theories have been advanced, but science
has at last replied with some authority. The following are the best
known authorities which this age of science has produced.

2. THE AGRICULTURAL THEORY.--The agricultural theory as it may be
called, because adopted by farmers, is that impregnation occurring
within four days of the close of the female monthlies produces a girl,
because the ovum is yet immature; but that when it occurs after
the fourth day from its close, gives a boy, because this egg is now
mature; whereas after about the eighth day this egg dissolves and
passes off, so that impregnation is thereby rendered impossible, till
just before the mother's next monthly.--_Sexual Science._

3. QUEEN BEES LAY FEMALE EGGS FIRST, and male after wards. So with
hens; the first eggs laid after the tread give females, the last
males. Mares shown the stallion late in their periods drop horse colts
rather than fillies.--_Napheys._

4. IF YOU WISH FEMALES, give the male at the first sign of heat; if
males, at its end.--_Prof. Thury._

5. ON TWENTY-TWO SUCCESSIVE OCCASIONS I desired to have heifers, and
succeeded in every case. I have made in all twenty-nine experiments,
after this method, and succeeded in every one, in producing the sex I
desired.--_A Swiss Breeder._

6. THIS THURY PLAN has been tried on the farms of the Emperor of the
French with unvarying success.

7. CONCEPTION IN THE FIRST HALF of the time between the menstrual
periods produces females, and males in the latter.--_London Lancet._

8. INTERCOURSE in from two to six days after cessation of the menses
produces girls, in from nine to twelve, boys.--_Medical Reporter._

THE MOST MALE POWER and passion creates boys; female girls. This law
probably causes those agricultural facts just cited thus: Conception
right after menstruation give girls, because the female is then the
most impassioned; later, boys, because her wanting sexual warmth
leaves him the most vigorous. Mere sexual excitement, a wild, fierce,
furious rush of passion, is not only not sexual vigor, but in its
inverse ratio; and a genuine insane fervor caused by weakness; just as
a like nervous excitability indicates weak nerves instead of strong.
Sexual power is deliberate, not wild; cool, not impetuous; while all
false excitement diminishes effectiveness.--_Fowler._
