ABSTRACT:
A device for smearing on slides a drop of liquid placed on a predetermined point on each slide has slide magazines containing a plurality of slides with the uppermost slide in each magazine having its upper face exposed for the reception of a drop of liquid towards one end thereof. Spreaders are adjacent the other ends of the slides. Means advance the spreaders out of contact with the slides, lower the spreaders into contact with the slides as they approach said predetermined points on the slides and slow the advance of the spreaders as they approach said points. The spreaders are retracted and the angle between each spreader and slide decreases to thin the smear of liquid. Means advance the uppermost slide in each magazine forwardly out of the magazine a predetermined distance to facilitate the removal of the slide by hand after the desired smear is made.
