Fig. II.—A, is a crawling Amœba (much enlarged).—Haeckel. The whole organism has the form-value of a naked cell and moves about by means of changeable processes, which are extended from the protoplasmic body and again drawn in. In the inside is the bright-colored, roundish cell-kernel or nucleus. B, Egg-cell of a Chalk Sponge (Olynthus).—Haeckel.

THE COMING INTO EXISTENCE OF MAN,
BY THE SLOW PROCESS OF DEVELOPMENT.
It is necessary now to take up the little mass of living matter, admitting its coming into existence by spontaneous generation as probable, and so probable that it almost amounts to a certainty, and follow it through the many changes it is about to make under the influence of the laws which govern evolution until it has culminated in man, and these laws still acting on the brain of man, perfecting it, and leading him on to the comprehension of a grander and nobler conception of the Almighty and of his works.
The start, then, must be made with a homogeneous mass of protoplasm, such as the existing Protamœba primitiva of the present day, which is a structureless organism without organs, and which came into existence during the Laurentian period. It is to this simplified condition, as I have previously stated, all fertilized eggs return before they commence to develop.
