APPENDIX. 597 



M. Duvaucel sailed in 1817 for Bengal, where he metM.Diard, as 

 we have already mentioned. Besides their joint remittances, M. Du- 

 vaucel has made one from Sumatra, in which were many precious ob- 

 jects we had not been able to procure. To his collections were added 

 notes and interesting descriptions. He is at present at Ghandernagor. 

 It was not till after MM. Diard and Duvaucel had transmitted their 

 rich collections that government thought proper to reimburse a part of 

 their expenses, and to enable them to prosecute their researches. 



M. Plee sailed for St. Thomas in 1820, whence he proceeded to Mar- 

 tinique and to the United States. He has sent us three miscellaneous 

 collections. 



M. Savigny was ordered to Senegal in 1820, by the minister for 

 naval alfairs, who had demanded from the administration of the Mu- 

 seum a person skilled in agriculture and botany : he is come back with 

 a considerable collection. 



M. Fontanier went first to the borders of the Black sea, whither he 

 was sent by the minister of the Interior. We have some reason to be- 

 lieve that he is now visiting mount Caucasus, his last communications 

 being dated from Teflis.
