HUXLEY AND TYNDALL ON EVOLUTION.

THE FORTY-SIXTH LECTURE IN THE BOSTON MONDAY LEC

TURESHIP, DELIVERED IN THE MEIONAON OCT. 2, 1876.

"NONE of the processes of Nature, since the time when Nature began, have produced the sliglitest difference in the properties of any molecule. We are, therefore, unable to ascribe either the existence of the molecules, or the identity of their properties, to the operation of any of the causes which we call natural. The quality of each molecule gives it the essential character of a manufactured article, and precludes the idea of its being eternal and self-existent.”

- PROFESSOR CLERK MAXWELL, "Lecture delivered before the British Association at Bradford,” in Nature, vol. viii. p. 441.

THERE is a wider teleology which is not touched by the doctrine of evolution, but is actually based upon the fundamental proposition of evolution. The teleological and the mechanical views of Nature are not necessarily mutually exclusive. The teleologist can always defy the evolutionist to disprove that the primordial molecular arrangement was not intended to evolve the phenomena of the universe.” – PROFESSOR T. H. HUXLEY in The Academy for October, 1869, No. 1, p. 13.

HUXLEY AND TYNDALL ON EVOLUTION.

In 1868 Professor Huxley, in an elaborate paper in the Microscopical Journal, announced his belief that the gelatinous substance found in the ooze of the beds of the deep seas is a sheet of living matter extending around the globe. The stickiness of the deep-sea mud, he maintained, is due to innumerable lumps of a transparent, jelly-like substance, each lump consisting of granules, coccoliths, and foreign bodies, embedded in a transparent, colorless, and structureless matrix. It was his serious claim that these granule-heaps, and the transparent gelatinous matter in which they are embedded, represent masses of protoplasm.

1. To this ainazingly strategic and haughtily trumpeted substance found at the lowest bottoms of the oceans Huxley gave the scientific name Bathybius, from two Greek words meaning deep
