Popular science monthly . The middle curves above represent extra tones in the mans voice and shmi them htlping the mcin or outside curve The cuive sho-j-n below, unlike theupper one. has no definite shape.

Boat spelledphonetically, or as it sounds,is of course h-o-t. Hence thecurves for (>, o, and t,are all that need concern ushere and the a can be left outof consideration. These curves look complicatedbut are really simple anddemonstrate most interestingpoints. In fact, they show ushow we realty speak, how we really mold air waves in pro-nouncing a given word. Theupper set of curves are in thenatural alphabet, as can beverified by comparing their shapewith b, o, and t as givenon page 68. The lower curve isthe kind the old-time physicsteacher would throw on a dark-ened screen as representingsound vibration
