Editor's Notes
Apologizes for not having written thanks TAE for his time and trouble -- makes reference to obtaining info on rawhide gearing -- Provides address of Dr. Roosa and says he is the best "aurist[?]" in NY [is this re TAE deafness?] -- Roosa was in audience when Mayer lectured on phono at NY Opthamological Society two weeks earlier -- Mayer's article on phono will appear in April Pop. Sci. Monthly -- Received the new tin foil and it is good and on readjusting the phono has obtained excellent results -- wants another recording point as his has worn out -- encloses a dozen magnetized needles all points are N and describes floating magnet experiment with them -- expects in a few days to take a series of accurate profiles of impressions from phono recordings -- asks how "disked" plate did on phono -- P.S. that Prof. Road of Columbia desires to purchase a phono for the Columbia cabinet of instruments
