he Ionometer and its Application to the Measurement of Radium and Rontgen Rays. H. GREINACHER(P hysikat. Zeitsch., 1914, 15, 410--415).-A simple and transportable form of directreading instrument is described, by means of which the ionisation in gases can be determined very conveniently. The construction is based on the same principle as that which has been adopted in the Bronson instrument. One of the most important differences between the two forms lies in the fact that no quadrant electrometer is required in connexion with the new type of ionometer. It is shown that the apparatus may be employed for the measurement of radium and radium emanation, and also for the tietermination of the intensity and the hardness of Rontgen rays.
