From John Cassin to S. F. Baird. 



PHILADA. 21 Aug. 1843 

 DEAR BAIRD: 



I should have written to you ere this, but have delayed it, hoping 

 to be able to get out the Academy's proceedings for July. 



Our Secretary, Dr. Zantzinger, has been out of town nearly 

 from middle of July to middle of August, and last Tuesday evening 

 was the first time I had an opportunity of urging the matter to him 

 personally he examined his documents, and found we had not 

 enough to make four pages of matter for July, and so it must be de- 

 layed until first September. The printing will commence next week, 

 immediately after the last meeting in this mo., which will be 29th, 

 so that by the first we shall have the Number ready, when I will 

 forward you copies immediately, and will also send copies to any 

 person that you may designate. The paper will be published ver- 

 batim, with the extensive exception that I took the liberty of inserting 

 "Swainson" after Tyrannula in the title of the paper making it 

 read "Species of the Genus Tyrannula, Swainson" etc. I hope it 

 will be in good time. 



Nothing going on Brazilian expedition gets off next week so 

 I hear. J. C. 



From John Cassin to Spencer F. Baird. 



PHILA. 6 Sept. 1843. 

 DEAR BAIRD, 



I have sent you two copies of Proceedings just out and have sent 

 all the others as you requested except those to your brother at 

 Washington, which I shall send to-morrow, not having enough of 

 them at the store. 



Your paper reads well and I will see that copies of this number 

 are sent to most of the Naturalists, in this country at least. The 

 proceedings, you know, are sent as published to all the European 

 societies. ... J. C. 



The following letter seems appropriate here, though a 

 little out of chronological order:
