BIOGRAPHICAL SKETCH OF ISAAC LEA, LL. D. XXXI 



Prince Maximilian. Dr. Eiippell had traveled mucli in Egyi)t and 

 Abyssinia, and had brought together an immense collection of art and 

 natural history for the museum. He showed Dr. Lea that the Cheiro- 

 therhim tracks of the Hilberthausen Limestone are accompanied by 

 Fucoids, and not by sun-dried sand cracks, as had been universally sup- 

 posed. The specimen in the museum is so perfect that it does not 

 admit of a doubt that these impressions are made by a plant. Dr. 

 Kiippell had by his industry during ten years made the collection of 

 the museum what it was. He exjjressed great interest in Dr. Lea's 

 Ijublications. 



After spending a few weeks at Scwalbach, Dr. Lea and his family 

 descended the Ehine and went to Amsterdam and Leyden. At the 

 latter place Dr. Lea visited the botanical garden, which is one of the 

 largest in Europe. He also visited the museum and saw Schlegel, who 

 very kindly olfered his services. The collection here in ornithology is 

 very extensive, and was considered at that time equal to any in Europe. 

 Dr. Schlegel showed Dr. Lea the eggs and a specimen of the extinct 

 Penguin. It came from Iceland, and Dr. Schlegel said it was extinct 

 since the last fifteen years. The collection of mollusca was very good. 

 Those of the Unionidce were badly arranged and incorrectly named. 

 Dr. Lea made the necessary corrections, and arranged the whole family. 



They subsequently* went to the Hjague, Antwerp, and Brussels. On 

 his return to Paris he met Dr. Daubnej", of Oxford, and had a long 

 conversation with him on geological subjects. The doctor had very 

 pleasant recollections of his visit to the United States ten years before, 

 and particularly of Philadelphia. He informed Dr. Lea that Dr. Buck- 

 land had become "hopelessly insane," which was sad news to him. On 

 a visit to a large manufacturer of china, who had three thousand live 

 hundred men in his employ, he informed Dr. Lea that the best and 

 largest part of his ware went to the United States; that without that 

 market the business would be worth nothing. The watchmaker to the 

 Emj)eror, of whom Dr. Lea purchased a fine watch, made the same 

 remark. He found that all his scientific friends were out of town at 

 this season, excepting Prince Charles Buonaparte and Boivin, whom he 

 frequently saw. The former spoke of their mutual friend, Mr. George 

 Ord, and Dr. Isaac Hays, for whom he had great regard. He spoke of 

 the Academy of Katural Sciences of Philadelphia, of its great collec 

 tiou, that in ornithology "being the best in the world." In regard to 

 the collection in Leyden, he "knew it better than any one else, having 

 spent eight months over it." His own collection he had given to the 

 island of Corsica, where they had recently formed a cabinet of natural 

 history. Dr. Lea dined with him, on which occasion several naturalists 

 were invited to meet him. 



Dr. Lea frequently visited M. Boivin, who had a fine collection of mol- 

 lusca, i)articularly those of fresh water; he was always kind and cour-
