Abstract
FINE filter membranes with maximum pore sizes less than 1µ are now readily available for collecting solid material suspended in a liquid. As the membranes are of very uniform thickness, they may be examined under a microscope for the determination of the sizes and nature of the particles deposited on them. We have used a simple and effective technique for preparing slides incorporating the sample membrane. The essential feature of the method is that the membrane is made transparent to permit the use of transmitted light without disturbing the particle distribution.
