The case preserves the optical instrument to count the blood complete of its optical part and its Hayem glass plate, a pipette for the blood signed Nachet and another for serum, a container (of which its glass part is missing), a tirrer and a set of special slides glass serving to cover the cell.
Despite a little lack of leather at the case, the condition is quite good.
