Popular science, like that of Mr. Blatchford, is in this matter as mild as old wives’ tales. Mr. Blatchford, with colossal simplicity, explained to millions of clerks and workingmen that the mother is like a bottle of blue beads and the father is like a bottle of yellow beads; and so the child is like a bottle of mixed blue beads and yellow. He might just as well have said that if the father has two legs and the mother has two legs, the child will have four legs. Obviously it is not a question of simple addition or simple division of a number of hard detached “qualities,” like beads. It is an organic crisis and transformation of the most mysterious sort; so that even if the result is unavoidable, it will still be unexpected. It is not like blue beads mixed with yellow beads; it is like blue mixed with yellow; the result of which is green , a totally novel and unique experience, a new emotion. A man might live in a complete cosmos of blue and yellow, like the Edinburgh Review
