Abstract

A VERY remarkable increase in light-scattering power is exhibited by gelatine solutions when the hydrogen-ion concentration approaches the value (about pH = 5) corresponding to the iso-electric point. This effect, which appears to have been known for some time, has been recently studied in detail by Kraemer and his co-workers, who give interesting curves showing the manner in which the Tyndall effect varies with pH and temperature (“Colloid Symposium Monograph”, vol. 4, and Journal of Physical Chemistry, May 1927).
