From the sex-life of plants to the sex-life of the lower animals there is, however, but a step which the teacher, according to his discretion, may take.
An early educational authority, Salzmann, in 1785 advocated the sexual enlightenment of children by first teaching them botany, to be followed by zooelogy.

In modern times the method of imparting sex knowledge to children by means, in the first place, of botany, has been generally advocated, and from the most various quarters.

Thus Marro (_La Puberta_, p.

300) recommends this plan.

J.Hudrey-Menos ("La Question du Sexe dans l'Education," _Revue Socialiste_, June, 1895), gives the same advice.
