Exercitationes de generations animalium by William Harvey of 1628 blood-circulation theory fame is published at London. Now 73, Harvey was physician to Charles I until 1648 and he says, "All animals, even those that produce their young alive, including man himself, are evolved out of the egg," but he thinks that lower forms of life are capable of primal generation and believes the pupa to be an insect egg (see Redi, 1668).
