credible, let them know that many hidden things are found in the nature of things original: "in rerum natura". Before their astute investigation, these things are rejected by most people because they are unknown. Yet, those same things are understood, cherished, and stored away like treasures by the few, with the greatest joy and profit. Therefore, whatever those things may be, I consider them worthy of being read. Once understood, they will perhaps adapt so well to your affairs that you will be grateful to the authors (whose memory is rare among many) and to me at some point. And if I find that these are well-received, I shall add greater things (God willing) in time. Farewell and enjoy.
