To test this speculation, we tried out adding an extra action to His’s protocol: re-melting the specimen (that had been dripped in paraffin wax) then putting it in molten paraffin inside the oven at sixty two °C. This developed a remarkable advancement within the infiltration in the paraffin wax, plus a corresponding improvement in segment high-quality (Fig. 3c).
