✦ Synopsis


Microscopic Inscription of Physiological Movements.--M. Marey has invented an instrument which enables him to make an exact record of the phenomena of circulation, respiration, and muscular and nervous actions. By employing a fine steel point and a thin layer of lampblack, movement.s which do not exceed one-tenth of a millimetre (~r~ in.) are magnified to great dimensions. The apparatus. can easily be carried in the pocket.--Comptes Rendus.
