Dear Sir : From the minutes for the years 1895 to 1899 it appears that 
you have presented to the Philosophical Society of Washington the follow¬ 
ing communications: 
Have these papers ever been published; and, if so, where and when ? 
The proceedings of the Society, 1895-1899, are now nearly ready for the 
press. Added value will be given them by inserting references to places 
of publication. Will you kindly supply without delay the necessary 
references to your own papers above cited? If any are unpublished, 
please so state. 
Very truly yours, 
Marcus Baker, 
Chairman Publication Committee. 
From the replies to this circular, supplemented by additions and veri¬ 
fications in libraries, the citations of places of publication have been 
prepared.
