The Genesis of Chemistry.

§ 68. But even if the alchemists did not discover the Grand Arcanum of Nature, they did discover very many scientifically important facts. Even if they did not prepare the Philosopher’s Stone, they did prepare a very large number of new and important chemical compounds. Their labours were the seeds out of which modern Chemistry developed, and this highly important science is rightfully included under the expression “The Outcome of Alchemy.” As we have already pointed out ([§ 48]), it was the iatro-chemists who first investigated chemical matters with an object other than alchemistic, their especial end in view being the preparation of useful medicines, though the medical-chemist and the alchemist were very often united in the one person, as in the case of Paracelsus himself and the not less famous van Helmont. It was not until still later that Chemistry was recognised as a distinct science separate from medicine.
