The important and thrilling incident referred to above took place in 1860, when I was two years old, but it was still an absorbing topic thirteen or fourteen years later, and is one of my most vivid recollections.

Wilberforce (1805-1873) was a great Churchman and, indeed, has been said to be the greatest prelate of his age, although his nickname “Soapy Sam” led to a popular depreciation of his merits. (This epithet originally meant that he was evasive on certain questions, but it took a further meaning from his persuasive eloquence.) In this instance he meddled with a subject of which he was ignorant. Owen, who instigated him to make this attack on Darwin and Huxley had at first welcomed the theory of evolution, but quailed before the orthodox indignation against the necessary extension of that theory to the origin of man. Huxley (1825-1895) was thirty-five years of age when he thus showed himself a strong debater and a power in the scientific world.

On tracing the line of life backwards, we see it approaching more and more to what we call the purely physical condition. We come at length to those organisms which I have compared to drops of oil suspended in a mixture of alcohol and water. We reach the protogenes of Haeckel, in which we have “a type distinguishable from a fragment of albumen only by its finely granular character.” Can we pause here? We break a magnet and find two poles in each of its fragments. We continue the process of breaking; but however small the parts, each carries with it, though enfeebled, the polarity of the whole. And when we can break no longer, we prolong the intellectual vision to the polar molecules. Are we not urged to do something similar in the case of life?... Believing, as I do, in the continuity of nature, I cannot stop abruptly where our microscopes cease to be of use. Here the vision of the mind authoritatively supplements the vision of the eye. By a necessity engendered and justified by science I cross the boundary of the experimental evidence, and discern in that Matter which we, in our ignorance of its latent powers, and notwithstanding our professed reverence for its Creator, have hitherto covered with opprobrium, the promise and potency of all terrestrial Life.
