It is then in the wonderful phenomenon of reproduction; in the evolution of the ovum; that we find the realization of that abstract principle – a creative force, upon which rests the entire science of life. Here, under the testimony of occular demonstration, do we discard those theories which once perplexed and encumbered the history of generation, and which, at the end of the seventeenth century, we lear,, amounted to no fewer than three hundred.
