sometime after I had obtained my specimen. I hope that you will 

 let me know all about those specimens I sent, Flycatcher, Thrush, 

 Warbler, & Shrew. Is the specific Character of Sciurus Capis- 

 tratus^Viz. ears and nose white, as given in Bachman's monograph, 

 essential. I got a specimen a few weeks ago, Length to end of tail 

 vertebrae 24 inches. Tail vertebrae, 11 inches. Weight 2 lbs. 

 5 oz. Female. Above grizzled yellowish Gray & Black, beneath 

 feruginous, as also are the ears & feet & tail beneath. Tail annu- 

 late with black. Nose brown. Bones light reddish. I do not 

 know what to refer it to except to S. Capistratus. 



When I was in Philadelphia in the summer I saw some flycatchers 

 which Townsend and others called Traill's Flycatcher, being the 

 same as those we have as " Mwcieapa Pusilla." My Idea is cer- 

 tainly that they are the latter, having compared them very carefully 

 with the descriptions, when fresh. I will send you one to see, in 

 order that you may decide-. Are you acquainted with any work 

 on Comparative Anatomy of Birds & Quadrupeds. I have been 

 using the article on Birds in Rees's Cyclopedia, 2 but not being able 

 to make head or tail out of the description of the muscles &c, I 

 threw it aside & wrote one myself. I however want to know such 

 of the names, of muscles, as I cannot find from Bell, or McCartney. 

 In what way do you keep Quadrupeds mounted ? or merely in the 

 skins : & also what length of time does it occupy you to skin & sew 

 up a duck, or warbler? You see I am very inquisitive. Don't 

 you think that you will come our way soon. I hope that we may 

 see you before long. I have a great deal of advice to ask, & articles 

 to show, also doubts to settle. I will send you those birds you 

 wished by the first opportunity and believe me to be most sincerely 

 Your Obedient Servant
