Thursday 31st. Mercury at 60 in the Morning—63 at Noon and 62 at Night.
More rain last Night & this forenoon—with heavy weather all day. Wind Easterly.
Siezed with an ague before Six Oclock this morning after having laboured under a fever all night.
Sent for Doctr. Craik who arrived just as we were setting down to dinner; who, when he thought my fever sufficiently abated, gave me a cathartick and directed the Bark to be applied in the Morning.
bark: Quinine derived from the bark of various species of the cinchona tree was ground into a powder and taken to reduce fevers.
