A memo concerning Edwin McDougall with the instruction for it to be placed in his file. These previous documents are found here, although all are from 1925. McDougall has developed a new sound recording technology offering quite a different alternative to the Phonofilm, Vitaphone and the others who photographically record the sound waves as the picture is recorded . With this new advancement the sound record is cut or "engraved" onto the film as the picture is recorded. This is a first. The name McDougall is also spelt McDougal in this file.
