'There, whilst perfecting himself in anatomy, he became more fully acquainted with such views as were held upon the circulation, modifications for the most part of the Galenic doctrine, with such objections thereto and glimpses of the truth as had been foreshadowed by Vesalius, and still more even by Servetus, who seems at least to have had some idea of the real nature of the pulmonary circulation.
