Title: Four books of Johannes Segerus Weidenfeld concerning the secrets of the adepts, or, of the use of Lully's spirit of wine : a practical work, with very great study collected out of the ancient as well as modern fathers of adept philosophy : reconciled together by comparing them one with another, otherwise disagreeing, and in the newest method so aptly digested, that even young practitioners may be able to discern the counterfeit or sophistical preparations of animals, vegetables and minerals, whether for medicines or metals, from true, and so avoid vagabound imposters, and imaginary processes, together with the ruine of estates.
