    • 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), →ISBN, page 35:
      [] 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.

      Fear, the product of guilt, is a true night-plant. Like some of those gigantic fungi the botanists tell of, it springs up in the dark, and in an hour of restless tossing, sudorific, horripilating wretchedness, canopies our bed with a phantom toad-stool of gigantic size. The load that the conscience can jauntily stagger under in the broad light of day, [] will, in the gloom and silence of the night, wear its bearer to his knees.

      That the skin is much affected under the sense of great fear, we see in the marvellous and inexplicable manner in which perspiration immediately exudes from it. This exudation is all the more remarkable, as the surface is then cold, and hence the term a cold sweat; whereas, the sudorific glands are properly excited into action when the surface is heated.

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 remaind.
