BT. 42.) TO GEORGE ENGELMANN. 399 
My wife and I well remember what a charming 
place Vallon is, and retain pleasant memories of our 
trip to the Saleéve under the charge of Madame De 
Candolle, despite the bad weather which spoiled the 
view. We should delight to revisit Switzerland. 
Having no children, it is not impossible that we may 
do so; but the time, I fear, is far in the future. .. . 
I have written a much longer letter than I had 
intended when I began. 
Believe me to remain, yours very faithfully, 
RAY. 
TO GEORGE ENGELMANN. 
CamBrincE, July 14, 1853. 
My prear ENGELMANN, — This cover has been ad- 
dressed to you for a long while, but I have delayed to 
fill and close it, not so much because you had not 
written, for I knew you must be very busy now, but 
because the convenient time has not exactly come. 
For I have been very busy. College work done up 
only last week; printing of “ Exploring Expedition 
Botany,” in which I have read proofs up to 220 pages, 
and gave to-night finished manuscript (except a few 
crooked points to settle in a family or two) up to the 
end of Rosacee (which will make about 450 pages. 
It fills up fast with the open pages adopted in these 
reports). I shall carry on the volume to 550 or 650 
pages, and the plates folio, already 56, shall carry up 
to 100, if Ican. There is next some tough work in 
Myrtaces and Melastomacez ; but as to the latter Nau- 
din has much cleared the way. Those done, and I 
think I may venture to work part of the time on the 
Lindheimer, Fendler, and Wright Monopetale. 
Agassiz returned most deliuhiod with his visit to 
you, and we talked much of you. .. .
