The end in this case is the will or love of procreating; the middle cause, by which the end is effected and into which it infuses itself, is conjugial love; the progressive series of efficient causes is the loving, conception, gestation of the embryo or offspring to be procreated; and the effect is the offspring itself procreated.

A further important point of resemblance between the Canis lupus and the Canis familiaris lies in the fact that the period of gestation in both species is sixty-three days.

The gestation for a Mugger is 35-40 days and for Gharials and Salties, 40-65 days.

But she is gestating, and gestation with her is always perturbing.
