The first day of the anniversary celebration closed with 
a reception given by Dr. and Mrs. Moore in the Director’s 
residence in the Garden. 
With the exception of personally conducted trips through 
the conservatories and unds of the Garden, no definite 
program was arranged for the forenoon of the second day 
of the celebration. This was done in order to give the 
visitors an opportunity to spend such time as they desired 
in the laboratories, herbarium, library, and Garden collec- 
tions. 
After luncheon, which was again served in the old resi- 
dence, the visitors assembled for the second scientific pro- 
gram, which consisted of the following papers: 
“RECENT INVESTIGATIONS ON THE PROTOPLASM OF PLANT 
CELLS AND Its CoLLompaL PROPERTIES”
