“When it is taken out, the matter will appear clearer than ever, and have a quicker scent. Then separate the grosser parts, which, however, are, not to be thrown39 away. Put this liquid into a gentle bath, that the remaining gross particles may perfectly subside. In the meantime, dry calcine, and extract the fixed salt of the grosser parts, separated as before mentioned, which fixed salt is to be joined to the liquor when filtrated. “Next take sea salt, well purified, melt it, and, by setting it in a cold place, it will run, and become clear and limpid. Take equal parts of both liquors, mix thoroughly, and having hermetically sealed them in a proper glass, let them be carefully exposed to the sun, in the warmest season of the year, for about six weeks. At the end of this space, the prim muens of the balm will appear swimming on the top like a bright green oil, which is to be carefully separated and preserved. Of this oil, a few drops taken in a glass of wine for several days together, will bring to pass those wonders that are reported of the Countess of Desmond and others; for it will entirely change the juices of the human body, reviving the decaying frame of life, and restoring the spirits of long lost youth.” The author who records this curious and wonderful discovery, remarks, “If after the medicine is thus prepared, any doubt be had of its efficacy, or of its manner of operation, let a few drops be given every day on raw meat to any old dog or cat, and in less than a fortnight, by the changing of their coats and other incontestable changes, the virtue of this preparation will sufficiently appear.”
