SUMMARY This paper describes a new approach to histoquantitation which makes fuller use of the visual expertise of the microscopist, provides a permanent visual two‐dimensional coded record, and allows mathematical exploitation of the collected data. The microscopic image of the specimen is traced directly onto computer data cards. A simple sketch records accurate quantitative data for areas and boundaries of as many components of the image as required, in a matrix of 840 points. Spatial relationships are maintained. The matrix is transferred by an Optical Mark Data Card Reader into a computer for extraction of a maximum of information.
