Observations diverses sur la sterilité, perte de fruict, foecondité, accouchements, et maladies des femmes, et enfants nouveaux naiz.

The first book on obstetrics published by a midwife. Louise Bourgeois was accoucheuse to the French court. She was one of the pioneers of scientific midwifery; her Observations was the vade mecum of contemporary midwives. She induced premature labor in patients with contracted pelvis, an idea probably derived from Paré.
