Plummer’s Pills.
Pil. Calomel. Co. originated from a formula devised by Dr. Andrew Plummer, Professor of Chemistry in the University of Edinburgh in the middle of the eighteenth century. Dr. Plummer first published his formula in the “Edinburgh Medical Essays,” 1751. It was only a slight modification of the Pilulæ Æthiopicæ which were already official in the Edinburgh Pharmacopœia. These were originally a combination of Ethiops Mineral with the golden sulphide of antimony, but the Edinburgh College had substituted calomel for the former.
