Oyl of Myrrhe per Deliquium.

Boil Eggs until they are grown hard, then cutting them in two, separate the Yelk, and fill the White with Myrrhe powdered, set them on little sticks placed conveniently on purpose, in a plate, or earthen pan, in a Cellar, or some such moist place, and there will distil a liquor to the bottom of the vessel, which you may take out, and keep for use. This is called the Oyl of Myrrhe: it is good to take away Freckles, and Tettars, applied outwardly.

Remarks.

Though this liquor, improperly called Oyl, is only the more soluble part of Myrrhe humected with the moisture of whites of Eggs, and the Cellar together, yet it is the best of any that have

been invented, whether you draw it in Spirit of wine, or distil this Gum in a Retort: for by spirit of wine the more Volatile part of Myrrhe is lost, either by Distillation, or Evaporation; and it is so Torrified in a Retort, that it loses its best vir∣tues; whereas per Deliquium what Volatile this Gum contains is preserved in its Natural being, for the humidities that mix with it are no ways capable of destroying or altering its nature.
