An early Malassez-type stage hemocytomer by Constantin Vérick signed both in the lid of the case and on the instrument.

The instrument is called in French “Compte-globules à chambre humide graduée”.

The little case is complete with the stage hemocytometer itself and its counting grid glass, a thin squarre piece of glass to put a drop of blood, a early-plastic tube, a small glass bottle and a pipette (signed by Stiassnie, the Vérick’s successor).

This kind of microspical device signed by Vérick are rare, we find more by Stiassnie or some other later ones.

The case measures 14×8,5 cm.
