Abstract: We observed phenomenologically the precipitations of barium sulfate which were made under various conditions, and we may conclude as follows : (1) The precipitation reaction of barium sulfate is divided into two processes: (2) Both processes go in parallel, and the main part of the first process is autopurification and orientation, and the process of the second consists in orientation and coagulation of a-aggregates. We may call the product of the first process the α-aggregate, and that of the second the β-aggregate. (3) The particle of barium sulfate which has been observed by the optical microscope is β-aggregate.
