Abstract
A fluid application device suitable for applying small quantities of blood to a microscope slide is described. The device has a housing within which a longitudinal aperture is formed. At one end of the aperture a transverse groove is formed which intersects the aperture. Small quantities of blood from a capillary tube may be introduced into the longitudinal aperture and permitted to spread through the transverse groove so that a relatively thin and uniform layer of blood is deposited on a microscope slide by drawing the device across a microscope slide.
