When the hour came for the great comparative anatomist and palæontologist, from his exalted position, to prepare a tribute to the memory of a naturalist of equal merit and of a far more thoughtful and profound spirit, to be read before the French Academy of Sciences, what a eulogy it was--as De Blainville exclaims, _et quel éloge_! It was not printed until after Cuvier's death, and then, it is stated, portions were omitted as not suitable for publication.[51] This is, we believe, the only stain on Cuvier's life, and it was unworthy of the great man. In this _éloge_, so different in tone from the many others which are collected in the three volumes of Cuvier's eulogies, he indiscriminately ridicules all of Lamarck's theories. Whatever may have been his condemnation of Lamarck's essays on physical and chemical subjects, he might have been more reserved and less dogmatic and sarcastic in his estimate of what he supposed to be the value of Lamarck's views on evolution. It was Cuvier's adverse criticisms and ridicule and his anti-evolutional views which, more than any other single cause, retarded the progress of biological science and the adoption of a working theory of evolution for which the world had to wait half a century. It even appears that Lamarck was in part instrumental in inducing Cuvier in 1795 to go to Paris from Normandy, and become connected with the Museum. De Blainville relates that the Abbé Tessier met the young zoölogist at Valmont near Fécamp, and wrote to Geoffroy that "he had just discovered in Normandy a pearl," and invited him to do what he could to induce Cuvier to come to Paris. "I made," said Geoffroy, "the proposition to my _confrères_, but I was supported, and only feebly, by M. de Lamarck, who slightly knew M. Cuvier as the author of a memoir on entomology." The eulogy pronounced by Geoffroy St. Hilaire over the remains of his old friend and colleague was generous, sympathetic, and heartfelt. "Yes [he said, in his eloquent way], for us who knew M. de Lamarck, whom his counsels have guided, whom we have found always indefatigable, devoted, occupied so willingly with the most difficult labors, we shall not fear to say that such a loss leaves in our ranks an immense void. From the blessings of such a life, so rich in instructive lessons, so remarkable for the most generous self-abnegation, it is difficult to choose.
