✦ Synopsis

A formula is derived to enable the calculation of the true height of an object, such as a shadowed latex bead, from electron micrographs. Knowing only the angle of shadowing and the length of the evaporated shadow, and by substituting these values in the derived formula, a microcomputer may be programmed to carry out the necessary computations. An example of such a microcomputer program is given. The correct determination of the height of particles by electron microscopy using the shadowing technique is one of the most accurate methods available for the determination of small particle height.

Subjectivity in selecting random grid squares for routine quantitative analysis can be circumvented through a combination of finder grids and a computer program. The simple BASIC program described in this paper generates a list of random grid-square numbers, which are sequentially analyzed. The conc
