attitude of opposition to Darwinian views may now be numbered on the fingers of a hand, whilst the rising school of thought is almost unanimous in favour of the doctrine of evolution. Very much of the opposition which the views contained in the Origin of Species had to encounter, leaving out of question, of course, the class opposition which was to be expected, was due to the absence of the details of the facts upon which those views were based, an absence which was rendered necessary by the hastened

factor of selection is brought to bear, either by natural agencies or by the conventional selection of man. Mr. Darwin's writing on this subject may be said to be his best and most important, though it is really difficult in a book like this to speak more highly of any one part than of the whole. Of artificial selection we need say no more here, but on the process of the evolution of new characters by natural selection, a word or two may be said on a certain want of definition in the use of a

distinguished botanists have studied the subject with painstaking fidelity, illuminating it with many curious facts not previously discovered. To improve the value of his paper by incorporating into it the latest information gained by himself and others, has been the purpose of Mr. Darwin in the work of revision; but the chief object has apparently been to apply its conclusions anew to the question of evolution. In accumulating the data on which his essay is based, Mr. Darwin investigated the

identical with a wild prototype either living or extinct, and that man has merely deprived them of liberty and regulated their environment and propagation in the manner most advantageous to each kind. At the present day, when the whole range of biological thought is so largely permeated by the principles of the doctrine of evolution, this objection will probably not be advanced. Yet, when it is remembered that such an authority as Col. Hamilton Smith held the belief that each breed of dog had

Organic beings resemble each other in descending degrees, so that they can be classed in groups under groups,─classes, orders, genera, c. The doctrine of evolution gives life to this arrangement and makes it truly a natural classification,-the idea of different degrees of community of descent being added to that of

In specimens in which the Nummuline layer constituting the ' proper wall' of the chambers was originally well preserved, and in which the decalcifying process has been carefully managed (so as not by too rapid evolution of carbonic-acid gas to disturb the arrangement of the serpentinous residuum), that layer is represented by a thin white film covering the exposed surfaces of the segments, the superficial aspect of which as well as its

antiquity of the human type has been brought prominently forward by Prof. Mivart.4 He shows, by a careful comparison of all parts of the structure of the body, that man is related not to any one, but almost equally to many of the existing apes—to the orang, the chimpanzee, the gorilla, and even to the gibbons—in a variety of ways; and these relations and differences are so numerous and so diverse that, on the theory of evolution, the ancestral form which ultimately developed into man must have

Those who do not admit the principle of evolution, must look at species as separate creations, or as in some manner as distinct entities; and they must decide what forms of man they will consider as species by

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.

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

any one of them would afford evidence almost alone sufficient to convince a student at least of the probability, if not of the certainty, that the processes of evolution may now in many cases be elevated into accepted facts, from out of the realm of mere hypothesis. It is at once the difficulty and the success of this new system of cosmic philosophy that it cannot be proved popularly, that is, it is impossible to show even an educated man in five minutes the fundamental proof of the principle of
