[...] I took my leave of them, & 'ran like a Lamp-lighter', the rest of the way to the Theatre; and in a most violent perspiration, clambered into the Shilling Gallery, where scarcely I cd gain admission, the rest of the House being extremely crowded, wch did not diminish the sudorific state of my person.

c. 1751, Roger Lonsdale, quoting Charles Burney, “Childhood and First Years in London, 1726–51”, in Dr. Charles Burney: A Literary Biography, Oxford: At the Clarendon Press, published 1965 (1986 printing), page 35

Fortunately the fever attacked me in the district town at the inn; I sent for the doctor. In half-an-hour the district doctor appeared, a thin, dark-haired man of middle height. He prescribed me the usual sudorific, ordered a mustard-plaster to be put on, very deftly slid a five-rouble note up his sleeve, coughing drily and looking away as he did so, and then was getting up to go home, but somehow fell into talk and remained.
