And among other things, I telling him what Dribble the German Doctor do offer of an instrument to sink ships; he tells me that which is more strange, that something made of gold, which they call in chymistry AURUM FULMINANS, a grain, I think he said, of it put into a silver spoon and fired, will give a blow like a musquett, and strike a hole through the silver spoon downward, without the least force upward; and this he can make a cheaper experiment of, he says, with iron prepared.
Allen, whom I knew at Cambridge, and a couple of apothecarys; these maintaining chymistry against them Galenicall physique; and the truth is, one of the apothecarys whom they charged most, did speak very prettily, that is, his language and sense good, though perhaps he might not be so knowing a physician as to offer to contest with them. At last they came to some cooler terms, and broke up.
However, the strong Aristotelian cast of Harvey's treatise encouraged continued discussion of long outdated questions in an outdated manner and, combined with his expressed disdain for "chymistry" and atomism, discouraged close cooperation between embryologists of different persuasions.
For a number of years past, as I have already observed, SAGE has delivered gratis, in this Museum; public courses of chymistry and mineralogy. He attracts hither many auditors by the ease of his elocution, and the address, the grace even which he displays in his experiments.
In that age, more than in our own perhaps, the influence of the individual was widely and intensely felt. Historical chymistry is only rendered possible by a detection of the subtle emanations, which it was supposed would for ever elude analysis, but which survive in those secret, frequently ciphered intercommunications.
Such was the dexterity with which this learned reader facilitated to his auditors the intricacies of science; and so true is it, that a man may know what he cannot teach. Boerhaave complains, that the writers who have treated of chymistry before him, are useless to the greater part of students, because they presuppose their readers to have such degrees of skill as are not often to be found.
Allen some good discourse about physick and chymistry.
If you were quite mistress of natural philosophy, he would now be hourly acquiring a knowledge of various branches, particularly natural history, botany, and chymistry. Pursue these studies, and also that of language. For fifty dollars you may get, in Philadelphia, a chymical apparatus, put up in a small box, with which more than one hundred experiments may be made.
Now, I cannot see that lectures can do so much good as reading the books from which the lectures are taken. I know nothing that can be best taught by lectures, except where experiments are to be shewn. You may teach chymistry by lectures. You might teach making of shoes by lectures!
Two men more different could perhaps not be selected out of all mankind. They had even attacked one another with some asperity in their writings; yet I lived in habits of friendship with both. I could fully relish the excellence of each; for I have ever delighted in that intellectual chymistry, which can separate good qualities from evil in the same person.
