BIOGRAPHICAL SKETCH OF ISAAC LEA, LL. D. XXXIII 



restricted to six or seven species, while in the United States they seemed 

 to be almost unlimited. 



Dr. Lea named those about which there bad been an,y doubt, greatly to 

 M. Desh ayes' satisfaction. He showed him his manuscripts on the whole 

 range of fossil and recent conchology, a stupendous work, which as- 

 tonished Dr. Lea. It was the result of thirty years' labor, and arranged 

 in a most convenient manner. It was written on cards about 3 by 4 

 inches. Of these there are forty thousand, and they are arranged 

 alphabetically for the genera and then for the species. Each species 

 has its whole synonymy complete with reference to author and page. 

 Then with each genus there was a set of cards with the authors who 

 have written on the genus, and these works are arranged chronologic- 

 ally. M. Deshayes promised Dr. Lea a copy of his manuscripts on the 

 Unionidcc, which promise he fulfilled within a year. 



On going to see M. Verreaux he showed Dr. Lea the manuscript of 

 Prince Charles Buonaparte's new edition of his Ornithology, to which 

 he (M. Verreaux) had added the synonymy, which is immense. Dr. 

 Lea procured from M. Verreaux four recent Terebratulcc. September 5, 

 1853, he paid his last visit to the Institute. In the library he found M. 

 Andresse, the librarian, who had made a complete list of all Dr. Lea's 

 works from 1827.* In the secretary's room he found Professor Flourens, 

 who kindly sent a messenger with him in order that he might "be placed 

 within the square." 



Here he found Cruvellier, Dumeril, and Professor Owen. Dr. Lea 

 was much gratified to meet Professor Owen, of whose presence in Paris 

 he was not aware. The professor read three ijapers in French before the 

 Institute : One on the invertebral column and the cranium, which he 

 intended publishing in Paris ; another of the papers was on the muscu- 

 lar and nervous systems of Terebratula, and there was also one on fossil 

 Chelonia. Some good chemical and other papers were also read. Dr. 

 Lea dined with M. Boivin, who told him of the fearful times during the 

 revolution of 1830 — " the three days." ]S'o one was permitted to go 

 into the street. All had to remain in their hotels, the inhabitants of 

 which clubbed their stock of provisions and did the best they could. 

 If they had ventured into the street they would have been shot. 



By appointment with M. Dumeril, Dr. Lea met him at the Jardin des 

 Plantes, where they found Professor Owen. After examining the col- 

 lection of skeletons, where the gorilla was the chief interest, they went 

 into the cabinet of fossil bones where there was a specimen of Mastodon 

 angustidens, nearly complete. 



Dr. Lea left Paris for London, regretting to part with many friends 

 whom he never expected to see again. After remaining a few days in 

 London he went to Hull, passing from the London basin of Tertiary into 



* Afterwards Dr. Lea sent all which he published, until 1876, so that their copies 

 are complete.
