lxvi PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [May I909, 



were made at the foot of Mont Leberon, in the Vaucluse, where he 

 obtained many new species of genera similar to those that he had 

 found in beds of approximately the same age at Pikermi. His obser- 

 vations in this case forced upon him the importance of migrations, 

 as an explanation of the apparently sudden changes in species. 



Preference has already been made, in the notice of Sir John Evans, 

 to Gau dry's excavations at St. Acheul. He continued to take an 

 interest in Pleistocene fossils to the end of his life, and published, 

 in conjunction -with M. Marcellin Eoule, who succeeded him in the 

 Chair at the Museum, au important work on ' Materiaux pour 

 l'Histoire des Temps Quaternaires.' 



The work by which Gaudry is most widely known in this country 

 and in Prance is the ' Enchainement du Monde Animal,' the first 

 volume of which appeared in 1878. In this he traced with a 

 master's hand the transformations which had affected the mammals 

 in Tertiary times. All who have made acquaintance with this 

 work must have yielded to its charm. It was completed in 1896 

 by another volume bearing the title ' Essai de Paleontologie philo- 

 sophique,' which contains a full development of his views. 



On March 9th, 1902, he was the hero of a great ceremonial 

 at the Museum of the Jardin, when, amidst the rejoicings of his 

 assembled friends, he was presented with a medal bearing his effigy 

 engraved by the sculptor Vernon. 



Gaudry resigned his Chair in 1904, and was succeeded by his 

 distinguished pupil and devoted colleague, Dr. Marcellin Boule. 

 He still continued, however, his work of investigation, particularly 

 on the mammals of Patagonia which had been brought home 

 by M. Tournouer : on this subject he left behind an unfinished 

 memoir. Gaudry communicated one paper to the Geological 

 Society ; its subject was ' The Mammalia of the Drift of Paris & 

 its Outskirts ' : it was printed in our Journal (vol. xxviii, 1872, 

 p. 491). 



Gaudry was elected a Eoreign Correspondent of this Society 

 in 1868, and a Poreign Member in 1874. The Wollaston Medal 

 was awarded to him in 1884, as a recognition of the value of 

 his palaeontological researches and the importance of his scientific 

 generalizations. He died on November 29th, 1908. 



Gaudry was greatly loved and esteemed, not only for his scien- 

 tific work, but for his high moral qualities. In the words of Prof. 

 Boule, we may say that, if he is allied to Lamarck and Geoffroy
