Rochester Dem. Chron 
Rochester.  N.Y. 
Dear Sir:- 
Article announcing discovery that a person blindfold can see moving objects without the aid of a fluoroscope by the X ray was sent to the Electrical Engineer New York and was in print before the San Francisco article was published there. 
I did not however experiment with blind persons. Nothing can be seen by the aid of a fluoroscope when one is blindfolded as stated in the San Francisco article, and there is good reason for the fact, because the X ray acting on the fluoroscope is turned into ordinary light. The ray does not pass through to the Eye. Last evening at the Laboratory a child totally blind was made to see her hand and other objects by the X ray but nothing could be seen through the fluoroscope. It is difficult to imagine that the statement in the California paper is correct. 
Yours truly.
Thomas A Edison
