Dr. Krause, indeed, thought otherwise. In the number of _Kosmos_ for February 1879 he represented Mr. Darwin as in his youth approaching the works of his grandfather with all the devotion which people usually feel for the writings of a renowned poet. {8b} This should perhaps be a delicately ironical way of hinting that Mr. Darwin did not read his grandfather’s books closely; but I hardly think that Dr. Krause looked at the matter in this light, for he goes on to say that “almost every single work of the younger Darwin may be paralleled by at least a chapter in the works of his ancestor: the mystery of heredity, adaptation, the protective arrangements of animals and plants, sexual selection, insectivorous plants, and the analysis of the emotions and sociological impulses; nay, even the studies on infants are to be found already discussed in the pages of the elder Darwin.” {8c} Nevertheless, innocent as Mr. Darwin’s opening sentence appeared, it contained enough to have put us upon our guard. When he informed us that, on his return from a long voyage, “it occurred to” him that the way to make anything out about his subject was to collect and reflect upon the facts that bore upon it, it should have occurred to us in our turn, that when people betray a return of consciousness upon such matters as this, they are on the confines of that state in which other and not less elementary matters will not “occur to” them. The introduction of the word “patiently” should have been conclusive. I will not analyse more of the sentence, but will repeat the next two lines:—“After five years of work, I allowed myself to speculate upon the subject, and drew up some short notes.” We read this, thousands of us, and were blind.
