A journey in Normandy with Sir J. D. Hooker had 
been planned for May, but Sir Joseph was unable to

European journey forty-eight years before. 
TO A. DE CANDOLLE. 
Hersarium, Kew, April 23, 1887. 
My pear De Cannot, — You will be a little 
surprised at the sudden transfer of Mrs. Gray and my-

spring of 1881. 
We expect to go to Paris early in May, but subse- 
quent movements are uncertain. 
Always, dear De Candolle, affectionately yours, 
Asa GRAY.

was so high or so very fine. I believe it is the highest
