TO A. DE CANDOLLE. 
CAMBRIDGE, December 29, 1881. 
I am doubtful if I have written to you since our 
return, and my New Year greetings will reach you 
somewhat late, but are very hearty. I could hardly 
have neglected to send you word of the satisfaction 
with which we look upon the fine bust of your father, 
which stands at one end of our herbarium; Robert 
Brown and William J. Hooker at the other, and your 
lithographic portrait overhead is replaced by the more 
striking photograph you gave us. 
At length we are settled in our home ; have had for 
the twenty-fifth time the annual Christmas family 
gathering, for which my study, being the largest room 
in the house,is always upturned and emptied, and I 
should be quietly at work upon the Compositz, were 
it not for an attack of lumbago, that uncomfortable 
attendant of old age, which just now interferes with 
my activity, without actually laying me up. . We, 
Mr. Watson and I, are still much aodapaed with itis 
distribution, and therefore in good part the study, of 
the recent collections which have accumulated here 
and are still coming in. Much valuable time do they 
consume. The most interesting are from Arizona, 
etc., near the Mexican frontier, among which those we 
have most to do with are by Lemmon and by Pringle.?
