Dear Sir:- 
We have your favor of the 14th inst*, and would say in re- 
ply, that the additions and corrections to the Manual, will be made 
as you suggested. It was only on the supposition that the matter 
proposed could be brought into the present space by a little re-ar- 
rangment, that we made the suggestion of condensation. There is 
no reason why the book should not be thoroughly accurate and compre- 
hensive, and so it will be done- 
We are in receipt this morning, of a communication from Mr. 
Barnes of Madison, informing us that he intended to begin upon the 
work of revision of the Field, Forrest and Garden Botany, at once. 
We send him, at his request, three copies of the present edition, and 
shall be glad to know of the progress of the work, from time to time. 
We trust there will be no question about our being ready to begin the 
composition at such time next year, as to have the new book out by 
the 1st of January, 1892. Additional plates of revisions and cor- 
rections will be made in Cambridge, and we will communicate with 
Messrs John Wilson & Son, requesting them to forward the work as rap- 
idly as possible. 
A new edition of the Manual goes n the press in the course of a 
week or two, so we should like to have this matter forwarded to us
