FIRST EDITION. G&M 6148. Portal was the first to appreciate the situation in placenta praevia, and had a clear insight into the actual findings and management of that entity, which is probably his most important contribution to the science of midwifery. He also demonstrated that version could be done with one foot, and taught that face presentation usually ran a normal course. Portal was a pupil of Mauriceau, and worked with him in the Hôtel Dieu. This important and eminently practical treatise was based on his personal experiences and observations. The plates depict abnormal and monstrous foetuses. See Cutter & Viets pp. 81–83.
