To the Editor:
—I have received a number of letters approving the position I have taken with regard to the performances of Willetta Huggins, and others expressing, somewhat after the manner of the communications of Dr. Babcock and of Dr. Nagel in The Journal, June 24 and 31, some reservations and a good deal of skepticism that sight sufficient to recognize colors should be possible despite a blindfold. With some acquaintance with the blindfold performances on the stage, I can say that the "goggles" type of blindfold used in Chicago would be regarded as one of the "easiest"—that is, easiest to circumvent. Sealing the eyelids with opaque court plaster, as suggested by Dr. Babcock, would be completely effective, as would also be a number of other devices known to those who have given attention to the subject; and the tests in a completely dark room would also be made decisive.
