Abstract:
In the late seventeenth century, then along the eighteen and nineteenth centuries the amount of the bloodlettings was measured by means of three pewter bleeding bowls that held three ounces of blood, about 300 millilitres. In the middle of the nineteenth century new and large bleeding bowls with metric graduations were manufactured only by the Parisian potters.
