✦ Synopsis

A new method for measuring the velocity of sound over short distances has been devised in which sixty pulses per second cause a sinusoidal curve to appear upon an oscilloscopic screen. As the receiving microphone is moved away from the sound oscillator, the crest of the sine curve moves across the oscilloscope, completing the circle in one-sixtieth of a second. The actual velocity of the sound is easily calculated after the distance moved by the microphone has been measured.

Application of the probability laws and the error curve shows that the method is very accurate, providing the alternating current maintains itself invariably at sixty cycles per second. The average of twelve hundred measurements gives 331.364 ~ o.o43 meters per second at zero degrees centigrade.

THE elastic wave in. the atmosphere caused by the explosion of Krakatoa on August 27, 1883, travelled, as is well known, several times around the earth at the average velocity of about 315 metres per second. That is, at a velocity that averaged about sixteen metres per second less than that of sound
