An electronic blood cell counting machine operating on a flow principle
is described. It is quick and easy to use; it can perform a red cell count in
ten seconds with an accuracy of ± 2.1 per cent (that is, 5000 cells counted
in 10 seconds for a 5 M count). Leukocyte counts can also be performed in
ten seconds with an accuracy of ± 9 per cent for a single count (500 cells
counted in a 5000 cu.cm. count).
