Electro-Chemistry: Dealing with the principals of electrolysis as applied to the storage battery and electroplating. 4.

This film also dealt with the action of the human ear and the peculiarities of Sound waves out-of-doors.

5. Sound Recording and Reproduction: As applied to the Talkie film production, the different types of sound track and how they are produced.
