_16th._—Walked with Tobin into the Park. Met various persons; among others, S——, the surgeon, as flighty and whimsical as usual. He walked with us; dropped us; then came up again; met another acquaintance, stopped with him, was presently with us again; and after first saying I was a deep observer of men and manners, asked me of what profession was the man he met. I had scarcely seen the man’s face, and, cutting Addison’s joke, desired him to give me the red hot poker out of his pocket, that I might swallow it as a first proof of my skill. He then said the man was a dentist. I replied, I was about to guess he was a Doctor, and should have been tolerably near the mark. Tobin tells me Dr. Beddoes is again going to lecture at Bristol on health and its preservation, that he hates physicians, that physicians hate him, and that he wishes to teach each man to be the guardian of his own health. Thomas Wedgewood, Tobin says, is so afflicted with bad digestion, that he is obliged to take several hours’ strong exercise every day. Shooting and turning are part of his amusements. Metaphysics, the study he most delighted in. I told Tobin I wished for a school of health, one principal branch of which should be exercise, and its proper direction, tending to move the limbs and muscles in all modes, by running, stooping, &c., and that social games, which should powerfully stimulate, ought to be practised; bowls, trap-ball, &c., in fine weather. Billiards, marbles, and whatever would engage the attention, and give variety of action, should be studied. I mentioned the above as those that first occurred to the memory. Parkinson, jun., a good mineralogist. His father was offered twelve thousand pounds, and the title of Baron for his son, by a German Prince (of Hesse, I believe), for the Leverian Museum. It is intended to remove this museum into Bond-street, make scientific arrangements, &c., and exhibit it at half-a-crown, or by annual tickets. At present it does not quite pay the interest of the money. Parkinson, sen., a lawyer, acting chiefly as steward to various persons. Much talk with Tobin, concerning some manuscript pieces written by his brother, and not a little praised by him. Stoddart and Clementi to dinner. Read a scene from Lillo’s “Fatal Curiosity” to them. Agnes and Wilmot concerting the murder. Critical remarks by S—— on the language. Called on N——, who mentioned an attack made on him by T——, editor of a magazine, meant to rival his Journal. The attack ignorant and artful. I advised either a perfectly good-tempered reply, or silence.
