150 more enlargements have been made, provided with printed 
labels, and await the completion of frames in order to be installed. 
Both the present grouping in the frames and the position of the 
frames on the walls are provisional and will be subject to better- 
ment from time to time as other photographs become available. 
The labels of the photographs thus far installed are given below, 
omitting the explanatory details and not attempting to reproduce 
the typography and alignment. In several cases where a label 
appears to be repeated, the accompanying photographs differ 
in detail, as would be evident if the labels were here reprinted 
in full.
