COMMITTEES ON BEHALF OF THE GOVERNMENT 283 
“The committee is pleased to find that no evidence of mold or other disinte- 
grating agents can be discovered upon the parchment by careful microscopic 
examination, nor any evidence that disintegration is now in progress. 
“The investigation has been facilitated by the photograph that was taken in 
1883, two years after the previous examination by a committee of the Academy, 
and we would suggest the desirability of taking another photograph of about the 
same size, at the present time, and from time to time in the future, as an aid to 
future investigation. 
“The committee does not consider it wise to apply any chemicals with a view to 
restoring the original color of the ink, because such application could be but par- 
tially successful, as a considerable percentage of the original ink was removed 
in making the copy about 1820, and also because such application might result in 
serious discoloration of the parchment; nor does the committee consider it 
necessary or advisable to apply any solution, such as collodion, paraffin, etc., with 
a view to strengthening the parchment or making it moisture proof. 
“The committee is of the opinion that the present method of protecting the 
instrument should be continued; that it should be kept in the dark, and as dry 
as possible, and never placed on exhibition. 
“Very respectfully, yours, 
“CHARLES F. CHANDLER, 
“ Chairman of the Committee.” 1**
