Abstract
The writer describes a piece of apparatus for recording respiration which does away with pneumograph, tambour, and connecting tube and substitutes a simple electrical mechanism of make and break fastened directly to the chest of the subject. Records may be taken over a considerable period of time while allowing the subject comparative freedom of movement. From Psych Bulletin 21:05:00363.
