Professor Haeckel, to whom Schleicher addresses himself, previously took occasion, in his splendid monograph on the 'Radiolaria',* to express his high appreciation of, and general concordance with, Mr. Darwin's views.
This truth is no doubt hard to see in the case of purely technical science; in books of wider range, such as Darwin's for instance, it is easy for any reader to feel the presence of a really great mind, producing inspiration of a different sort from that of the most excellent up-to-date examination text-book.
But it is by no means necessary to visit the tropics or the conservatory for examples of these wonders. Our own Asa Gray, one of Darwin's instant proselytes, was prompt to demonstrate that the commonest of our native American species might afford revelations quite as astonishing as those exotic species which Darwin had described.
And even a cursory glance at the history of the biological sciences during the last quarter of a century is sufficient to justify the assertion, that the most potent instrument for the extension of the realm of natural knowledge which has come into men's hands, since the publication of Newton's 'Principia, is Darwin's 'Origin of Species.
Darwin's "Voyage of the Beagle" is to me the best book of the kind ever written; it is one of those classics which decline to go into artificial categories, and which stand by themselves; and yet Darwin, with his usual modesty, spoke of it as in effect a yachting voyage.
It came up for a second time, but created little excitement, in 1844, when an anonymous work, "Vestiges of the Natural History of Creation," directed the attention and the interest of scientists again to Lamarck and his doctrine. But this interest also soon came to an end, until through Darwin's first publication the half-forgotten man again suddenly attained great honor.
But his mind was not yet ready to accept so bold an idea and he swept it aside. The people of this wild neighborhood interested Darwin very greatly, and he describes them with care. In this connection a charming trait of Darwin's character comes beautifully in evidence.
Mivart diverges from the Quarterly Reviewer or not. The Reviewer declares that Mr. It looks, at first, as if this meant, that Mr. Darwin's views being false, the opposition to "religion" which flows from them must be needless. But I suspect this is not the right view of the meaning of the passage, as Mr. I may assume, then, that the Quarterly Reviewer and Mr.
He simply 'announced. This oracular attitude certainly affected some of the younger men greatly, but fortunately for the success of the new gospel one of these younger men translated the oracular into a more popular and reasoned form. It may be said to have done for Emerson's message the kind of service rendered by Huxley to Darwin's.
Darwin's researches prove that the skeleton of the wings in domestic pigeons has hardly varied at all from that of the wild type; while, on the other hand, it is in exactly those respects, such as the relative length of the beak and skull, the number of the vertebrae, and the number of the tail-feathers, in which muscular exertion can have no important influence, that the utmost amount of variation has taken place.
