heather bush, on the declivity of a low abrupt bank, where the only chance of dislodging the young birds was to eject them over the side of the nest remote from its support upon the bank.] As the young cuckoo was blind, it must have known the part of the nest to choose by feeling from the inside that that part was unsupported. Such being the facts, we have next to ask how they are to be explained on the principles of evolution. At first sight it seems that although the habit saves the bird which

do well to remember that this grade of mental evolution is reached very early in the psychical development of the human child. In my next work I shall adduce evidence to show that children of one year, or even less, are able to distinguish pictures as representations of particular objects, and will point at the proper pictures when asked to show these objects. Coming now to cases more distinctly indicative of reason in the strict sense of the word, numberless ordinary acts performed by dogs

commencement of inflammatory softening of the brain, unconsciously imitate every word that is uttered, whether in their own or in a foreign language, and every gesture or action which is performed near them. The same sort of tendency is often observable in young children, so that it seems to be frequently distinctive of a certain stage or grade of mental evolution, and particularly in the branch Primates. Other animals, however, certainly imitate each other's actions to a certain extent, as I

seventy-fourth year, and it is fitting that his last known scientific utterance should be on a botanical matter. For there was an evolutionary progression in his own researches. His first insight into science was attained through geology; he moved on to zoology, and thence to botany, with the thread of world evolution connecting each subject. Fifty years before this letter was written he knew practically nothing of botany, and the exigencies of geological and zoological observations and deductions

In the next chapter I shall make some few remarks on the probable steps and means by which the several mental and moral faculties of man have been gradually evolved. That such evolution is at least possible, ought not to be denied, for we daily see these faculties developing in every infant; and we may trace a perfect gradation from the mind of an utter idiot, lower than that of an animal low in the scale, to the mind of a Newton. ———————————— CHAPTER V.

. No doubt man, in comparison with most of his allies, has undergone an extraordinary amount of modification, chiefly in consequence of the great development of his brain and his erect position; nevertheless, we should bear in mind that he is but one of several exceptional forms of Primates. 14 Every naturalist, who believes in the principle of evolution, will grant that the two main divisions of the Simiadæ, namely the Catarhine and Platyrhine monkeys, with their sub-groups, have all proceeded

A BRIEF summary will be sufficient to recall to the reader's mind the more salient points in this work. Many of the views which have been advanced are highly speculative, and some no doubt will prove erroneous; but I have in every case given the reasons which have led me to one view rather than to another. It seemed worth while to try how far the principle of evolution would throw light on some of the more

. What Mr. Darwin does not seem to us to have treated with anything like the subtlety and depth with which he investigated the laws of organic change, is the psychology of human nature, though even here he had sagacity enough to put his finger on the right spot, though he failed to enter into the moral phenomena which he rightly held to contain the essence of the problem. He was so anxious to show that the moral life of man is but an evolution from the moral life of the lower animals, that he tried

will not do, therefore, any longer to despise the worm. Indeed, not only is it useful in creating the mold which makes the earth fertile, but it helps also to preserve for man the memorials of the past. Its mission is to cover all naked surfaces with its ejecta. The earth which passes through its intestinal canal is rendered soft and fertile, and covers and preserves whatever it is deposited upon. The discovery of the value of the worm in the scheme of evolution (it is not scientific to say

the creation as given in the Bible and also that of evolution, although Professor Huxley in an able review demonstrated the logical impossibility of the acceptance of the two theories. His doctrines excited controversies which are not yet at an end, and many eminent scientists and naturalists have embraced the principles embodied in his teachings, and great changes have been consequently induced in the methods of biology and kindred sciences. In other works he pursued the same line of thought

all those who were brought even into momentary contact with him, was the beauty of his character. There never was a more honest man. Not only was he superior to the ordinary pettinesses and jealousies of the discoverer— as is shown by the well-known story of his conduct with regard to Mr. Wallace's simultaneous statement of the evolution hypothesis—but he was incredibly scrupulous in verifying all his facts, in listening to every objection, in balancing every consideration that was brought before

any rate abstain from opposing them; a host of young and ardent investigators seek for and find inspiration and guidance in Mr. Darwin's great work; and the general doctrine of Evolution, to one side of which it gives expression, finds in the phenomena of biology a firm base of operations whence it may conduct its conquest of the whole realm of nature. But it is not only in physical and natural science that the revolutionary influence of The Origin of Species is seen. It is not too much to say

distance that stretch away from him, put this point with extreme clearness. ''The evolutionary process, supposing it to exist, must have had a beginning: who began it? It must have had material to work with: who furnished it? It is itself a law or system of laws: who enacted them?'' The inevitable answer to these questions justifies the assertion which Canon Barry made the same evening in Westminster Abbey, that ''the fruitful doctrine of evolution, with which Darwin's name would always be

bearings to classification based on Darwin's theory of descent, rest on the principle of evolution. We see the fruitfulness of the same doctrine in archaeological and geological science, and in astronomy we recognize its influence in the revival of the Kantian hypothesis of the origin of the universe. It is making medicine into a science; to those who are not content except with practical results we may point to the revolution it has effected in the study and treatment of zymotic disease. Nor

past and present times, and their geological succession. The homological structure, embryological development, and rudimentary organs of a species remain to be considered, whether it be man or any other animal, to which our attention may be directed; but these great classes of facts afford, as it appears to me, ample and conclusive evidence in favour of the principle of gradual evolution. The strong support derived from the other arguments should, however, always be kept before the mind. The sole

gradual evolution, will not readily admit that the sense of smell in its present state was originally acquired by man, as he now exists. He inherits the power in an enfeebled and so far rudimentary condition, from some early progenitor, to whom it was highly serviceable, and by whom it was continually used. In those animals which have this sense highly developed, such as dogs and horses, the recollection of persons and of places is strongly associated with their odour; and we can thus perhaps

conditions. I was not, however, able to annul the influence of my former belief, then almost universal, that each species had been purposely created; and this led to my tacit assumption that every detail of structure, excepting rudiments, was of some special, though unrecognised, service. Any one with this assumption in his mind would naturally extend too far the action of natural selection, either during past or present times. Some of those who admit the principle of evolution, but reject natural
