M. le Clerc, The Compleat Surgeon — Chirurgical Operations (1696)
“ To let out the Matter, the Patient must be oblig'd to lean on one side, stopping his Mouth and Nose, and puffing up his Cheeks, as if he were to blow vehemently; then if Blood appears, a greater quantity of it may be taken away than if it were Matter, in regard that a Flux of Matter weakens more than that of Blood. It is also worth the while to observe, that in making the Incision, the Intercostal Muscles ought to be cut a-cross, that the side of the Ribs may not be laid bare, by which means the Wound will not so soon become Fistulous. ”
