The following are quotes:
- “In whatever system where the weight attached to the wheel should be the cause of motion of the wheel, without any doubt the center of the gravity of the weight will stop beneath the center of its axle. No instrument devised by human ingenuity, which turns with its wheel, can remedy this effect. Oh, speculators about perpetual motion, how many vain chimeras have you created in the like quest. Go and take you place with the seekers after gold.”
- “There is a certain secret ‘secret principle’ in nature by which liquors are sociable to some things and unsociable to others. Thus water will not mix with oil but readily with spirit of wine or with salts. [Just as water ‘elects’ to mix with ethyl alcohol or with salts, so it ‘chooses’ not to mix with oil, Similarly, water will sink into wood while quicksilver will not, but quicksilver will penetrate and amalgamate with metals, which water will not. Likewise, aqua fortis (nitric acid) will dissolve silver and not gold, while aqua regis (mixed nitric and hydrochloric acid) will dissolve gold and not silver. Nonetheless these rules are not written in stone]. But a liquor which is of itself unsociable to a body may by a mixture of a convenient mediator be made sociable. So molten lead which alone will not mix with copper or with Regulus of Mars, by the addition of tin is made to mix with either.”
- “I have found neither gold nor silver, but something that unspeakably delights me: the ‘human Os intermaxillary’.”
- “If my efforts have led to greater success than usual, this is due, I believe, to the fact that during my wanderings in the field of medicine, I have strayed onto paths where the gold was still lying by the wayside. It takes a little luck to be able to distinguish gold from dross, but that is all.”
