Two electromagnetic microbarographs designed by H. Benioff to respond to pressure variations in the frequency range from five cycles per second to one cycle in thirty seconds approximately, and with sufficient sensitivity to record the natural unrest of the atmosphere, have been in operation at the Seismological Laboratory in Pasadena for approximately two years.
