In some work which was being conducted at Wesleyan during the past year, on the effect of pressures upon some living organisms, it was noticed that when the water containing these organisms was subjected to pressures of more than a few hundred atmospheres a turbidity was usually developed. This suggested that something in the solution was being precipitated by means of pressure. Upon inspection it was found that this was some of the colloidal constituents in the water, and it was desired to determine whether or not pressure alone would cause the precipitation of a pure colloidal suspension. A number of colloidal suspensions were chosen at random and subjected to pressures varying from a few atmospheres to 17,000 atmospheres.
