Dear Chamberlaini- 
Thank you very much for the specimens of Pogo- 
natum which came a few days ago. Thank you also for the infor¬ 
mation in regard to the changes of names mentioned. I like to 
keep in touch with such changes. 
I shall ho glad to have you keep an eye open for the Polytri- 
ehaceae this summer. If it more convenient for you to do so 
send the specimens direct of Providence. 
l/e are all jjretty welll here. H avc been enjoying a thaw. 
There is a good prospect that I shall be in New York City some 
time between now and the 20th. I will lwt you know just when 
later. I expect to go down into Pennsylvania on a U.S.junket, 
for about 10 days, and shll have a little work to do out on Long’ 
Island either going or coming. 
Cordially,
