Brilliant trackers of Pansophy depend upon the wanderings of the Author, the treasury of secrets brought forth from Arabia and Spain, 
the foundation of the college founded by four persons in particular, the artful creation of the tomb, the manifestation of the Brotherhood in its own time in the mind, steadily, again and again in the aforementioned treatise; pray, by bringing the reputation of the Worshipful Brotherhood of the Rosy Cross together with all these things, then certainty on the same matter will appear brighter than even the noontime sun, and more well-known to the whole of Germany! Would this supreme philosopher's entire body of knowledge still existed in print today! To this we could similarly compare the Golden Fleece from the Argonautica, that is, according to the judgment of Paracelsus, a skin that encompasses the Tincture of Natural Philosophers, or rather a book showing how to make gold from other metals, just as the Worshipful Brotherhood promises in its own coat of arms; the Apple of the Hesperides; Mulciber with Mars and Venus and the glory of the Sun; the Golden Bough of Aeneas; Jupiter with his golden rain penetrating the brazen tower; Vulcan with the crown of Ariadne and the chariot of the sun, resplendent in gold, silver, and jewels,
and other tales chosen from the Poets, chiefly about the unavoidable bath of Phoebus, and Pluto's family and infernal rule, in each of which chemical secrets, most noble and most obscure, barely known to true natural philosophers, are described by the ancients finely and carefully.
Finally, I shall reveal, in part, for those that do not known, the mystery of the Microcosm, with a harmonious comparison to oth the greater and smaller world. Mankind has been wisely called the Microcosm by the Greeks (in Latin, the "small world"), on account of it being harmoniously composed from the greater one. It is made of three essential (one might say “creative”) parts; and if one is left out or not distributed correct, the greatest errors both in theology and philosophy tend to spring forth after it! When one inappropriate piece is provided, more follow; or when one mistake is allowed, of course many follow. Therefore, a careful youth presses still more to properly understand this mystery.
Having had a few weeks ot process it, I think the word here is allatum (written as allatū, but with the macron faded), being the perfect passive participle of affero, meaning "to bring forth."
Tinctura Physicorum; seems like a technical term from Paracelsus.
