MILLER SQUARES. Total ruled area: 7mm x 7mm.

For counting components of greatly varying densities in a specimen. The frequency of the sparsely distributed particles in the major square is related in the proportion 1:10 to that of the denser populations counted only in the smaller square.

A squared reticle can be used for counting. Here the basic principle is that a small area of the specimen is analyzed in order to obtain information about the total area. This removes much irksome work and is preferable in certain instance to analyzing the whole area. For example when it is desired to compare the proportion of large to small particles in a specimen, by using the Miller Disc, the smaller particles may be counted only in the small square, the result being multiplied by ten for comparison with the number of larger particles in the large square.
