DR. ABADIE'S LETTER. 



Fort Mifflin, Pennsylvania, August 8, 1845. 



Sir : Herewith I enclose a correct list of the collection of birds I tendered to you 

 last fall, whicli you did me tlie lionor to accept ; either to form llie nucleus of a 

 cabinet for liie Medical Departinoiit of the Army, or to be disposed of as you may 

 deem it ejn»cJient, by presenting it in tiie name of the ftlodical Department to the 

 National Institute, or to any other scicnlilic institution you may prefer. 



I regret very much, that during my lonjj absence from home, what was a very 

 complete coi. ction of the birds of the United States, should, from want of proper 

 care and attention hav9 been reduced to some two hundred species only : fortunate- 

 ly, many very rare species have escaped destruction, viz : the Carracara Eagle, male 

 and female, Florida Jay, Canada Jay, CiilF Swallow, a new species of Tyrant Fly. 

 catcher. Ibis Fusea, Brown Crane, Spoonbill, Darter, Guillemot, Petrel, &.c„ &c. 



I have retained, thus long, the list, for the purpose of availing myself of oppor- 

 tuniliesafforded here to replace some specimens, or to nmew such as were not as 

 good preparations as I could have wished : I will continuo to do so in order to 

 make the collection a complete one. 



I would call your attention to a curious preparation accompanying the "Whist- 

 ling Swan" of its sternum, showing the singular manner in which the trachea 

 after reaching it, dips between the lamina of the bone, which separate to receive it ; 

 making a turn upon itself near the enciforms cartilage, it returns to the entering 

 point and goes to be distributed in the usual manner to the lungs. Thus more 

 than a third of the trachea is actually contained within the sternum, the external 

 coat of the trachea being continuous with the internal periostiuin of the bone. 



The birds are accurately labelled with the English and Latin names ; they are 

 securely packed in two boxes, ready to^be shipped through whatever channel you 

 may please to indicate. 



I have the honor to be, very respectfally, your'most obedient servant,
