the uniting several small particles of a natural body into sensible masses, or concretes, whereby it becomes so and so figured and determined, and is endowed with such and such properties.

CONCRETION is also the act whereby soft bodies are rendered hard; or an insensible motion of the particles of a fluid or soft body, whereby they come to a confluence. It is indifferently used for induration, condensation, congestion, and coagulation.
