The notes upon botanical subjects are full and interesting. 

 Among other observations, Mr. M. thinks he has discovered the 

 tree which furnishes the Siam Gamboge, a point hitherto undeter- 

 mined. He has no doubt that it is the Garcinia pictoria of Rox- 

 burgh. He mentions several other trees which afford a yellow 

 resin of inferior quality, more or less resembling Gamboge, and 

 also several trees which afford Kino, or a gum resembling it. The 

 paper was referred to the Publishing Committee. 



Dr. Wyman exhibited the prepared sternum of a male 

 Trumpeter Swan, (Cygnus buccinator.} 



The keel of this bone contains a remarkable cavity, extending 

 its whole length, designed to receive the trachea, which traverses 

 it from top to bottom, and then is folded upon itself, and returns by 

 the opening at the top into the chest. It only exists in the male. 



Dr. Abbot exhibited the nest and eggs of the Northern 

 Humming-Bird. (Trochilus colubris.) 



Mr. Snelling laid on the table a Catalogue of Seeds brought 

 home by the Exploring Expedition, furnished him by Capt. 

 Wilkes. He offered selections from them to gentlemen de- 

 sirous of attempting their cultivation.
