Abstract

A few months since a prospector brought me a specimen of earth of uncommon appearance from the Black Hills of South Dakota for analysis with the hope that it might be something of value. It proved to be Fuller's earth of exceptional quality and I considered the result of sufficient interest to be published. Below is given the result of the analysis of the specimen dried in the air for two years. Two other analyses from the literature available are given for the sake of comparison. The per cents of the constituents of a theoretically chemically pure hydrated aluminum silicate with five molecules of water of crystallization are also given.
