THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 159 
your collection but I fear I cannot repay you for the great labour 
it will cost you. Prof. Silliman has not yet sent me the proof- 
sheets of your monography [68] to correct. You must insist on 
this being done (if you do it not yourself); for if the press is cor- ` 
rected in New Haven, the paper will be full of errors. Will you 
please request him to print a few extra copies of it. 
Mr. Le Conte arrived here from the South a day or two ago. I 
informed him of your intention of writing on the Violets, at 
which he appeared a little disappointed! He will never publish 
anything in my opinion, as I think I know him well. You have 
probably seen his beautiful Drawings—but has he not made too 
many species? With the Southern Violae I am not much ac- 
quainted, but there is not one yet found in the Northern States 
unknown to me & there are not more than 7 or 8 species. Le 
Conte makes a great many species of two or three variable kinds 
growing here. 
am of your opinion respecting Sprengel. He appears to 
examine specimens much too slightly. . He has given the same 
thing sometimes three different names! Bridel, on the other hand, 
appears to be too accurate if I may use the expression, for he 
makes too nice distinctions. No doubt many American species 
have been confounded with European ones which they much re- 
semble, such as the Climacium americanum &c., but Bridel has 
hardly confirmed any of our determinations except when species 
peculiar to this country were named. 
I shall inclose you some remarks on your last return-list if 
I have time. You will allow me to be candid & state my objections 
when we differ in opinion. This is the only way to get at the 
truth. 
A few days ago a friend of mine (the Rev. Ed. Hitchcock of 
Conway, Mass.) sent me for examination a book of drawings of 
Fungi 120 in number, done by his wife. I should be very glad to 
have you look over them, but he wishes the book to be returned 
by June 4th next, as that will probably be the only opportunity of 
sending to him for some months to come. Now if you know of any 
means of returning them to me by that time if I should send them, 
please to inform me as soon as possible. I shall send you dried 
specimens of many of the plants figured. 
I am now driving at my Botany of the Northern States [89]. I
