          Cambridge, Thursday Evening. 


 My Dear Friend 


 We were waiting anxiously for your letter, 
 which besides the delay at its first start, was somehow 
 missent to Roxbury, from which it reached me to-day. 
 I am right glad to hear from you all again. 
 You do not say whether you had a pleasant trip home. 
 If your visit was in anyway enjoyable I am very 
 glad. None of you could have enjoyed it more than I did. 
 Pray do not talk of "time and trouble" in such a 
 connexion. I am busily at work to be sure,
 but my health is not like to suffer. I got such 
 a nice rest in July that I am as strong and 
 vigorous as possible. Herbert enjoys himself more 
 and more, I think. He is a capital companion 
 and I am getting so used to his prattle and so fond 
 of him that I shall not very readily give him up.
 He is an excellent boy in every respect. 


 I will send you my botanical illustrations 
 with pleasure. I shall forward them tomorrow, by 
 Adams Express "to be kept till called for. You 
 can send there for the parcel. I have got 
 so used to the more complete series of the Lowell
 Lectures, that I could not get on with these. 
 Still if they will be useful to you, I know not why 
 you should not have the use of them again. 


 Olney wrote me that you had sent him 
 the Psilocarya. Like most young botanists, he is 
 all agog with his new species, is anxious it should 
 be secured right away, and gave me a pretty direct 
 intimation that he would like to have me give it 
 his own name, and publish it with all speed! He has 
 just sent me some fresh specimens, full length, which 
 are very striking, the queer 3-winged stems. I think
