I was sitting by Doctor Franklin [says Jefferson], and observed to him that I thought we should except books (from the obligations of the non-importation association formed in America to bring England to terms); that we ought not to exclude science, even coming from an enemy. He thought so too, and I proposed the exception, which was agreed to. Soon after it occurred that medicine should be excepted, and I suggested that also to the Doctor. "As to that," said he, "I will tell you a story. When I was in London, in such a year, there was a weekly club of physicians, of which Sir John Pringle was President, and I was invited by my friend Doctor Fothergill to attend when convenient. Their rule was to propose a thesis one week and discuss it the next. I happened there when the question to be considered was whether physicians had, on the whole, done most good or harm? The young members, particularly, having discussed it very learnedly and eloquently till the subject was exhausted, one of them observed to Sir John Pringle, that although it was not usual for the President to take part in a debate, yet they were desirous to know his opinion on the question. He said they must first tell him whether, under the appellation of physicians, they meant to include _old women_, if they did he thought they had done more good than harm, otherwise more harm than good." This incident brings back to us, as it doubtless did to Franklin, the augurs jesting among themselves over religion.[31] It is to be regretted that many other easy pens besides that of Jefferson have not preserved for us some of those humorous stories and parables of which Franklin's memory was such a rich storehouse. Doctor Benjamin Rush, one of his intimate friends, is said to have entertained the purpose of publishing his recollections of Franklin's table-talk. The purpose was never fulfilled, but the scraps of this talk which we find in Dr. Rush's diary are sufficient to show that, even in regard to medicine, Franklin had a stock of information and conclusions which were well worth the hearing.
