It would be impossible to specify from what particular mammifer the soul must escape, in order to penetrate a human organism. It would be impossible to decide whether, before reaching man the soul has successively traversed the bodies of several mammifers, of more or less complicated organism; if it has passed through the body of a cetacian, then of a carnivorous creature, then of a quadrumane, the last term of the animal series. A pretension to detail would be a stumbling block to such a system as ours. To maintain, for instance, that our soul is transmitted to us by the quadrumane, would be incorrect. The intelligence of the quadrumane is inferior to that of many animals more highly placed than he in the zoological scale. Apes, which compose only one family in the very numerous order of quadrumana, are animals of middling intelligence. They are malicious, cunning and gross, and possess only a few features of the human face, and even these belong to but few species. All the other quadrumanes are bestial in the highest degree. It is not, therefore, in the quadrumana that we must look for the soul to be transmitted to man. But there are animals endowed with intelligence which is both powerful and noble, who would have a title to be accredited with such an honour. Those animals would vary according to the inhabited parts of the earth. In Asia, it may be that the wise, grave, and noble elephant is the depositary of the spiritual principle which is to pass into man. In Africa, the lion, the rhinoceros, the numerous ruminants which fill the forests may, perhaps, be the ancestors of the human race. In America, the horse, the wild ranger of the pampas, the dog, the faithful friend, the devoted companion of man, everywhere are, it may be, charged with the elaboration of the spiritual principle, which, transmitted to the child, is destined to develop itself, to increase in that child, and become the human soul. A writer in our time has called the dog a candidate for humanity. He little knew how true his definition is. It will be urged, in objection, that man cannot have received the soul of an animal, because he has not the smallest remembrance of such a genealogy. To this we reply that the faculty of memory is wanting in the animal, or is so fugitive that we may consider it _nil_. The child can therefore receive from the animal only a soul unendowed with memory. And, in fact, the child itself is totally destitute of that faculty. At the moment of his birth he differs not at all from the animal as regards the faculties of his soul. It is not until twelve months have elapsed that the soul makes itself evident in him, and it is afterwards perfected by education. How, therefore, should the child remember an existence prior to his birth? Have we any memory of the time which we passed in our mother's womb?
