Abstract
1. The electrical properties of quartz particles covered with material adsorbed from ragweed extracts are those typical of ampholytes. 2. The isoelectric point of these particles covered with a fresh extract was at pH 3.9. On standing this shifted to pH 4.3 where it was stabilized for some time. 3.Experiments with paraffin oil and collodion particles showed that these particles acquired similar amphoteric surface properties in ragweed extracts, corresponding exactly with those found when the adsorbent was quartz.
