Christopher Grummet wrote this work in the late 17th century. Subtitled, "Manifest Declaration of the Sanguine and Solar Concealed Liquor of Nature," it was selected by Hans W. Nintzel for inclusion in the R.A.M.S. Library. There are a few footnotes in this volume that are attributed to "D.H." Although I have seen footnotes under these same initials in other R.A.M.S. works, the person's identity remains unknown. This Volume of The R.A.M.S. Library of Alchemy also includes "Universal and Particular Processes" by John de Monte Snyder. A much longer work by Monte Snyder is available as The R.A.M.S. Library of Alchemy Volume 31, "The Metamorphosis of the Planets." The symbols in this short work may be more easily understood using R.A.M.S. Volume 21, "Alchemical Symbols."
