The Complete Work of Charles Darwin Online [page] 4 THE EFFECTS OF CROSS AND SELF-FERTILIZATION IN THE VEGETABLE KINGDOM. By Charles Darwin, M.A., F.R.S., etc. New York: Appleton Co. Sacramento: A.S. Hopkins. We have here another volume of the minute and laborious researches of the great naturalist whose life is devoted to the demonstration of the doctrine of Evolution. The main object of Mr. Darwin in these experiments is to throw new light upon the difficult subject of hybridism, which has

the conditions of life, and thus stands in the closest connection with life itself. It throws light on the origin of the two sexes and on their separation or union in the same individual and lastly on the whole subject of hybridism, which is one of the greatest obstacles to the general acceptance and progress of the great principle of evolution.   Mr. Darwin has deemed the results of his experiments of sufficient value to justify the details. The peculiar style of Darwin renders the work

If we admit the principle of gradual evolution, there must formerly have existed many species which presented every successive step between the wonderfully elongated tail-coverts of the peacock and the short tail-coverts of all ordinary birds; and again between the magnificent ocelli of the former, and the simpler ocelli or mere coloured spots on other birds; and so with all the other characters of the peacock. Let us look to the allied Gallinaceæ for any still-existing gradations. The species

, des espèces, it is manifest that at least a large number of naturalists must admit that species are the modified descendants of other species; and this especially holds good with the younger and rising naturalists. The greater number accept the agency of natural selection; though some urge, whether with justice the future must decide, that I have greatly overrated its importance. Of the older and honoured chiefs in natural science, many unfortunately are still opposed to evolution in every

-structure of a system of philosophy was laid down which has already, even in its author's life-time, revolutionised almost every phase of scientific thought. The Journal of that voyage now forms one of the most interesting books which either the young naturalist or the student of philosophy can read, for in its pages are to be found the elements of the doctrines of evolution which Mr. Darwin's later work has so firmly established. In the present book the geological observations made during the voyage

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. ON THE DEVELOPMENT OF THE INTELLECTUAL

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

varieties of plants, on which the author's conclusions are based, and this provides some tough work for non-scientific readers; but the concluding chapters, giving the general results, are eminently striking and attractive, and Mr. Darwin himself suggests a way by which those who are not naturalists can master the principles and methods of the work without reading its entire contents. The bearing of the facts upon the general question of evolution by descent is rather implied than insisted upon

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

the question of the evolution of species. We have seen that, according to Lartet, existing mammals belonging to several orders have larger brains than their ancient tertiary prototypes. It has often been said that no animal uses any tool; but the chimpanzee in a state of nature cracks a native fruit, somewhat like a walnut, with a stone.37 Rengger38 easily taught an American monkey thus to break open hard palm-nuts; and afterwards of its own accord, it used stones to open other kinds of nuts, as
