Mr. Oakes Ames-2. 
I have asked the Museum to forward a copy 
of Volume 23 of the Contributions and trust that 
you will receive it promptly. The fourth part 
of the volume has been submitted for printing. 
The fifth part will conclude the volume. The 
last part is now complete except for two genera 
of Composites which are to be contributed by 
Doctor Robinson and Doctor Greenman. 
Sincerely yours, 
Division of Plants
