Dr. Torrey also alludes, in the same letter, to my recent journey in the Indian country:  “I am anxious to make some inquiries of you concerning your expedition to the Falls of St. Anthony, &c.  Though your principal object was more important, perhaps, than natural science, I hope the latter was not entirely neglected.  I know that you have heretofore devoted as much of your attention as possible to the observation of natural objects, and the preservation of specimens, and your last expedition was through a country well deserving of your highest exertions.  I know that part of it is the same as that explored while you attended Gov.  Cass, many years ago; but much of the ground, if I am rightly informed, is new.  You know that I have long devoted much of my time to the study of N. American botany, and that I am collecting materials for a general Flora of our country.  Now, my dear sir, if you or Mr. Houghton (the young gentleman whom, I am informed, accompanied you) have made any collections in botany, I should esteem it a peculiar favor to have the examination of the specimens.

“Our Lyceum prospers.  We have removed to the N.Y.  Dispensatory, a new building lately erected in White Street, where we have excellent accommodations.  The Corporation of the city had use for the N.Y.  Institution, and nearly all the societies who occupied it have been obliged to decamp.  You doubtless have heard of the death of Dr. Mitchell.  Dr. Akerly will pronounce his eulogy soon, and probably Dr. Hosick will give a more elaborate account of his life.

“Mr. Cooper now devotes himself to shells and birds.  If you have anything rare or new in these departments, we should be greatly obliged to you for such specimens as you can spare.

“Dr. Dekay went to Russia with his father, Mr. Eckford, last summer.”

23d.  A friend and shrewd observer from Detroit, writes:  “You ask how we like our new Governor.  Very well.  He is a well-informed plain man, unassuming in his manners and conciliatory, always ready for business, and accustomed to do everything en ordre.  His wife is a fine-looking agreeable woman, with several pretty well-behaved children.”

Another correspondent says:  “Mr. Porter is very much such a man as A. E. Wing, and will, no doubt, generally suit the citizens of the territory,”

30th.  W. Ward, Esq., says:  “I remove hence to Washington, with no certain prospects, only hopes.  I cannot go without thanking you for much enjoyment in the hours passed with you, and for the manifestations of interest and friendship.”

Nov. 12th.  Rev. W. S. Boutwell says:  “I am happy to hear that my friend and classmate, Porter, is at Mackinack, on his way to this people.  The Lord speed him on his way.”

22d.  Dr. Houghton writes from Fredonia, communicating the results of his analyses of the Lake Superior copper-ores.
