A few days ago a letter reached me from Professor Lehmann, in answer to my communication eighteen months ago. He is quite desirous of continuing the correspondence. He is now particularly engaged with Hepaticæ, and is anxious to obtain our species, and especially original specimens of those described by the late Mr. Schweinitz, etc. He has sent a box (which by this time I hope has arrived in New York) containing about five hundred species of plants and several botanical books. He also writes that he has applied to Nees von Esenbeck for dried specimens of all the species of Aster cultivated in his garden in order to transmit them with the monograph by that author; but not having arrived in time they will be sent with his next package. I wish to be particularly remembered to Mrs. Torrey and to Mr. Shaw, not forgetting my lively little friends J----, E----, and M----, whom I very much long to see. I had intended long before this to have written to Mr. Shaw, but have not yet had leisure. Please say to him that I am much obliged for the papers he has been so good as to send me. I wish to know whether he has yet apostatized from the anti-tea-drinking society, of which Mr. S. and myself were (“par nobile fratrum”) such promising members. Please say to him that I have not yet drunk tea, but am doing penance upon coffee, milk, and water. May I trouble you for the very earliest possible answer to this, which will much oblige Yours very respectfully, A. GRAY. HAMILTON COLLEGE, June 9, 1834.
