My dear Mr. Powell: 
Your letter of March £2 is just here. 
The specimens will come along by Monday and I will 
send you word of them at the earliest possible time. 
I am sending this letter off to you for the purpose 
of enclosing a few strips of surgeon’s plaster. On 
Monday I will send you another tube so that you will 
be well supplied. 
You do not realize how much the mat-1 
©rial you are sanding to me means, 
How that I have your permission to 
ohange the strips on the specimens already in hand and 
bo m&&8 any changes that will help their appearance 
and utility I intend to go at them at once. It will 
onl# be necessary to remove the tape and secure the 
specimens to the sheet in just the position that you 
have placed them in. 
Yol 7 of Orchidaceae will be for¬ 
warded on Thursday next. 
Yours faithfully, 
CL,kw. Cw
