, p. 24). We must patiently smile at such objections, just as we do when some lady of seventeen summers seriously informs us that she has never seen any gill slits in her neck, though she has often looked for them! Still more hopeless is it when the objector creates an impossible theory of his own, and then begins to smash it up, under the fond delusion that he is answering the difficulties of Evolution. Scarcely less humorous is the position of those who cannot accept the teachings of science

intelligent animal. By slow degrees, by many attempts, by making many and small improvements, such mechanical wonders have become the servants of man. Probably we could no more show all the steps in the evolution of such a machine than we can produce all the steps in the evolution of man from the lowest vertebrate animal. In such cases we should fix our attention on the steps. To ask a man to jump from the ground to a third story window seems absurd enough, yet by a little contrivance called a ladder

This has long since been demonstrated to be a false account of the matter; but how few men, in the most civilised countries, habitually think of the facts as they are? In face of this fact, one dimly realises that thousands of generations may have to pass away before the average man will think correctly of the other and more complicated relationships between himself and the universe. Even to men who recognise that Evolution affords the only reasonable explanation of facts as we see them, there

see the length and breadth of the unifying doctrine of Evolution. And by degrees the world will be clothed in new grandeur, and human life will show the possibilities of new beauty and a higher achievement. To fully grasp the teaching of Evolution is to pass from a condition of helpless isolation to one of universal brotherhood with the universe. Man is no longer to be treated as a solitary, maimed lodger in a world of dust and ashes. But by learning the laws of the universe, and by knowing

At the dinner given on the occasion by the Philosophical Society, Mr. Huxley responded to the toast of the evening with the speech of which an authorised version is given by Mr. L. Huxley in the Life and Letters of his father (Volume I., page 479). Mr. Huxley said, But whether that doctrine [of evolution] be true or whether it be false

expression of extreme variation, nor on that of evolution being guided only by Natural Selection. Can Sir Wyville Thomson name any one who has said that the evolution of species depends only on Natural Selection? As far as concerns myself, I believe that no one has brought forward so many observations on the effects of the use and disuse of parts, as I have done in my Variation of Animals and Plants under Domestication; and these observations were made for this special object. I have likewise

, received yesterday, and for the present of your work, which no doubt I shall soon receive from Dr. Hooker.2 The sudden appearance of so many Dicotyledons in the Upper Chalk3 appears to me a most perplexing phenomenon to all who believe in any form of evolution, especially to those who believe in extremely gradual evolution, to which view I know that you are strongly opposed. The presence of even one true Angiosperm in the Lower Chalk4 makes me 1. Oswald Heer (1809-83) was born at Niederutzwyl

of species. Thus he wrote: With respect to books on this subject, I do not know any systematical ones, except Lamarck's, which is veritable rubbish; but there are plenty, as Lyell, Pritchard, etc., on the view of the immutability. By Pritchard is no doubt intended James Cowles Prichard, author of the Physical History of Mankind.1 Prof. Poulton has given in his paper, A remarkable Anticipation of Modern Views on Evolution, 2 an interesting study of Prichard's work.

too completely your own and my child. The reference is to Mr. Wallace's review, in the April number of the Quarterly, of Lyell's Principles of Geology (tenth edition), and of the sixth edition of the Elements of Geology. Mr. Wallace points out that here for the first time Sir C. Lyell gave up his opposition to evolution; and this leads Mr. Wallace to give a short account of the views set forth in the Origin of Species. In this article Mr. Wallace makes a definite statement as to his views on

These remains are from the Coryphodon bed or lower Eocene of New Mexico. This bed is below that in which the Orohippus occurs. The oldest ancestor of the horse, as yet undiscovered, undoubtedly had five toes on each foot, and probably was not larger than a rabbit, perhaps much smaller (American Journal of Science, November, 1876, and April, 1892). These discoveries of the many stages of the horse are of the highest value to science. They answer every expectation of the doctrine of Evolution

CHAPTER II. MAN AND THE REST OF THE ANIMAL FAMILY You may have stood under the steep side of a mountain and felt that no human being could ever climb it, but on wandering perhaps miles away you came to a path which by a gradual slope led you to the top of this very mountain. So it is with the evolution of man. If you begin with your Carlyles, Ruskins, Gladstones, Darwins, Spencers, then man seems to stand forth in solitary mountain glory far above all animals. But there is another way of

the whole list of points in this description. I do this because some uneducated people, who have just heard of Evolution, talk loudly of the missing link. During the last forty years this phrase has been the shield of much ignorance, and I cannot but think it has been greatly exaggerated sometimes by really scientific men. We have seen (p. 19) that, at the beginning of the vertebrate series, there were links enough to join the vertebrates to the invertebrates. No fewer than three classes of

, demonstrated exactly the same formation on a human prehistoric skull received by him from Santos, in Brazil. Poor Virchow, like all men who, through prejudice, oppose the truth, had shifted and shifted in vain! I give these facts because he is by far the greatest scientist who opposed Evolution, and because he showed so clearly the methods to which these opponents are all reduced. Haeckel continues: It is established that the oldest mammalia 'were small insectivorous mammals with a very primitive

to succeeding generations. It can be clearly shown that the most wonderful instincts with which we are acquainted namely, those of the hive-bee and of many ants could not possibly have been acquired by habit (p. 206). These passages have a great historical interest quite apart from the doctrine of Evolution. They show the cloudy metaphysics which then hung around the whole question of instinct. In consequence of this metaphysical puzzle, Darwin's task of dealing with instinct was rendered

differences between queens, workers, and drones are largely, if not altogether, due to differences in food. This is only another way of saying it is a chemical difference. Geddes and Thompson, in their remarkable book on The Evolution of Sex, p. 43, say: Nor are there many facts more significant than this simple and well-known one, that within the first eight days of larval life the addition of a little food will determine the striking structural and functional differences between worker and

CHAPTER XI. THE EVOLUTION OF THE WORLD MR. HERBERT SPENCER, in First Principles, p. 30, says: Respecting the origin of the universe three verbally intelligible suppositions may be made. We may assert that it is self-existent; or that it is self-created; or that it is created by an external agency. By the aid of Dean Mansel, he proves that each of these suppositions is inconceivable. The Very Reverend Dean says: The conception of the Absolute and the Infinite, from whatever side we view it

We come down, then, finally to force as the ultimate of ultimates. Space, time, matter, motion, as we know them, are all either built up of, or abstracted from, experiences of force. These scrappy quotations from First Principles are not given as representing Mr. Spencer's argument, but merely to clear the way for our inquiry into the Evolution of the World. Perhaps it would be of help to some readers to refer to Professor Karl Pearson's newer setting of this doctrine. Many great minds have

unlike forces previously existing i.e., all forces manifested at any time must link on to those which went before. This shows one of the necessary conditions of all evolution viz., continuity. (3) There is no such thing as matter at rest, absolutely. The molecules of matter are in incessant motion, even in those masses which we think are quite fixed. (4) There is no such thing as empty space. Matter is everywhere, and is either ponderable or imponderable as ether. This imponderable ether it is
