Abstract

Phonograph experiment. Wax##I tried for Edison an experiment on Doll waxes. I heated the waxy just before the needle to obliterate the previous record. We ironed a wax with a hort iron, & we warmed up a piece of platinum wire & let it run just before the rec. knife. Result:- It would do it all right but it left the wax limpy & not true.
