Pearl Powder compound.
Take Pearl Oriental, white Coral, each half an ounce; Crabs Eyes 1 ounce; levigate them into an absolute Alcohol, on a Marble.
I think testaceous Powders exert their Virtues much easier and sooner when fine, than when course. Its to be used either alone, or in Pearl Juleps, to 2 scruples or 1 dram in 12 ounces.
