The increasing importance of the chemistry of colloids is giving them a wide recognition in the general chemistry texts of college grade. In a lesser degree they are included in the high school books but the information is often so condensed as to offer little of value. The writer believes that two or three class periods near the end of the year's course should be devoted to this subject and this article will attempt to present basic fact upon which may be built a discussion of colloids for high school pupils.
