Стр. 57 - A few naturalists, endowed with much flexibility of mind, and who have already begun to doubt the immutability of species, may be influenced by this volume; but I look with confidence to the future, to young and rising naturalists, who will be able to view both sides of the question with impartiality.
Стр. 52 - Beagle,' as naturalist, I was much struck with certain facts in the distribution of the organic beings inhabiting South America, and in the geological relations of the present to the past inhabitants of that continent. These facts, as will be seen in the latter chapters of this volume, seemed to throw some light on the origin of species — that mystery of mysteries, as it has been called by one of our greatest philosophers.
Стр. 59 - ... when we regard every production of nature as one which has had a long history; when we contemplate every complex structure and instinct as the summing up of many contrivances...
Стр. 58 - ... carried him beyond mere species-mongering in 1850, onehalf of Lamarck's arguments were obsolete and the other half erroneous, or defective, in virtue of omitting to deal with the various classes of evidence which had been brought to light since his time. Moreover his one suggestion as to the cause of the gradual modification of species — effort excited by change of conditions — was, on the face of it, inapplicable to the whole vegetable world.
Стр. 59 - Bastian's book had been turned upside down, and he had begun with the various cases of Heterogenesis, and then gone on to organic, and afterwards to saline solutions, and had then given his general arguments, I should have been, I believe, much more influenced. I suspect, however, that my chief...
Стр. 52 - The strengthening of the observant faculties,' and the rest of the Henslowian programme must give way to the imperious necessity of presenting to the examiner candidates equipped with at least the minimum of text-book formulas reproducible on paper. I do not speak in this matter without painful experience. The most astute examiner is defeated by the still more astute crammer. The objective basis of the study on which its whole usefulness is built up is promptly thrown aside. If you supply the apple...
Стр. 56 - although the fourth edition is now in many respects out of date, I do not know its equal for breadth of view, sobriety of speculation, and accuracy of detail.
Стр. 52 - I did not study botany' (i. 48). Yet we must not take this too seriously. Darwin, 1 * when at the Galapagos, 'indiscriminately collected everything in flower on the different islands, and fortunately kept my collections separate.
Стр. 52 - Wallace, of Huxley and of Moseley, show that that result is the fault of the man and not of the method. The right moment comes when the fruitful opportunity arrives to him who can seize it. The first strain of the prelude with which the ' Origin' commences are these words: ' When on board HMS "Beagle" as naturalist, I was much struck with certain facts in the distribution of the organic beings inhabiting South America.
Стр. 55 - No more important discovery," says Sachs (History, 142), "was ever made in the domain of comparative morphology and systematic botany. The first steps toward this result, which was clearly brought out by Hofmeister twenty-five years later, were secured by Robert Brown's researches, and he was incidentally led to these researches by some difficulties in the construction of the seed of an Australian genus.
