180 SPENCER FULLERTON BAIRD 
yclept Wislizenus, who hath wandered in New Mexico and written 
a book and is very full of prickly pears, burs, and cacti aiberhaupt. 
Him also will I move to communicate with you. I wish you would 
come hither and see these men, whom you would find not good 
naturalists merely, but accomplished and agreeable persons. 
Since the above was written I have seen Herr Lischke, who wil 
write you in High Dutch, touching Umtausch, etc., also Capt. Haug, 
of the Austrian Army, hath given me a slip as the address of a great 
exchanger of exchanges, who dwells somewhere, and would fain 
communicate. 
From George P. Marsh to Spencer F. Baird. 
WasHINGTON, June 14, 748. 
Dear Bairp,— 
Mr. Henry came to me this morning to consult me in regard to 
the matter in which you wrote 2° by Gen. C. and will no doubt 
advance you funds from time to time. He will begin moderately, 
but I think there will be no difficulty in ultimately securing any 
reasonable amount. I wish you would come to Washington before 
the adjournment, and let me introduce you to Mr. H. provided that 
you will for the time lay aside a little of your modesty, and swagger 
enough to make a properimpression. . . . I did not see Gen. C, 
being out when he called, and therefore congratulate Mrs. Churchill 
instead on his well merited promotion. I am, 
Very sincerely yours, 
Georce P. Marsu. 
Professor Joseph Henry to Spencer F. Baird. 
WasHINGTON, July 8th, 1848. 
My pear S1r,— 
I received some time since a communication from Professor 
Haldeman suggesting the propriety of allowing you a small sum of 
money from the income of the Smithsonian Institution for the pur- 
pose of procuring drawings to illustrate your scientific researches. 
I have referred this subject to Dr. Morton and Mr. Haldeman as a 
commission to report upon the merits of your investigations and am 
20 Qn making illustrations for the Smithsonian publications.
