16 THE POPULAR SCIENCE MONTHLY. 



the same effort. Each remains great ; but not all of them together 

 could arrest the current. Agassiz's strong efforts throughout the 

 United States, and indeed throughout Europe, to check it, really 

 promoted it. From the great museum which he had founded at 

 Cambridge, from his summer school at Penikese, from his lecture- 

 rooms at Harvard and Cornell, his disciples went forth full of 

 love and admiration for him, full of enthusiasm which he had 

 aroused and into fields which he had indicated ; but their powers, 

 which he had aroused and strengthened, were devoted to develop- 

 ing the truth he failed to recognize; Shaler, Verrill, Packard, 

 Hartt, Wilder, Jordan, and a multitude of others, and above all 

 the son who bore his honored name, did justice to his memory by 

 applying what they had received from him to research under 

 inspiration of the new revelation. 



Still another man deserves especial gratitude and honor in 

 this great progress Edward Livingston Youmans. He was per- 

 haps the first in America to recognize the vast bearings of the 

 truths presented by Darwin, Wallace, and Spencer. He became 

 the apostle of these truths, sacrificing the brilliant career on 

 which he had entered as a public lecturer, subordinating himself 

 to the three leaders and giving himself to editorial drudgery in 

 the stimulation of research and the announcement of results. 



In support of the new doctrine came a world of new proofs ; 

 those which Darwin himself added in regard to the cross-fertili- 

 zation of plants, and which he had adopted from embryology, led 

 the way, and these were followed by the discoveries of Wallace, 

 Bates, Huxley, Marsh, Cope, Leidy, Haeckel, Miiller, Gaudry, 

 and a multitude of others in all lands. The last theological 

 efforts against these men we shall study in the next chapter.* 



THE Koyal Institution of Great Britain, in a memorial resolution to Professor 

 Tyndall, adopted at a general meeting, speaks of him as one " who by his brilliant 

 abilities and laborious researches nobly promoted the objects of the institution 

 and conspicuously enhanced its reputation, while at the same time he extended 

 scientific truth and rendered many ne\v additions to natural knowledge practi- 

 cally available for the service of mankind." 



* For Agassiz's opposition to evolution, see the Essay on Classification, vol. i, 1857, as 

 regards Lamarck, and vol. iii, 1860, as regards Darwin; also Silliman's Journal, July, 1860; 

 also the Atlantic Monthly, January, 1874; also his Life and Correspondence, vol. ii, p. 

 647 ; also Asa Gray, Scientific Papers, vol. ii, p. 484. A reminiscence of my own enables 

 me to appreciate his deep ethical and religious feeling. I was passing the day with him at 

 Nahant in 1868, consulting him regarding candidates for various scientific chairs at the 

 newly established Cornell University, in which he took a deep interest. As we discussed 

 one after another of the candidates he suddenly said : " Who is to be your Professor of 

 Moral Philosophy ? That is a far more important position than all the others."
