The title-page, which is almost illegible, is written in red ink. It runs, "Stat Jove principium, Musae, Jovis omnia plena. Prelectiones Anatomiae Universalis per me Gulielmum Harveium Medicum Londinensem Anatomie et Chirurgie Professorem. Anno Domini 1616. Anno aetatis 37 prelectae Aprili 16, 17, 18. Aristoteles Historia Animalium, lib. i. cap. 16. Hominum partes interiores incertae et incognitae quam ob rem ad caeterorum Animalium partes quarum similes humanae referentes eas contemplare." The motto prefixed to the title-page that "everything is full of Jove" is an incorrect quotation from the third Eclogue of his favourite author Virgil, of whom he was so enamoured that after reading him for a time he would throw away the book with the exclamation, "He hath a devil." This particular line appears especially to have struck his fancy, for he quotes it twice in his treatise on development, and he works out the idea which it represents in his fifty-fourth essay. He there shows that he understands it to mean that the finger of God or nature, for with him they are synonymous terms, is manifest in every detail of our structure whether great or small. For he says: "And to none can these attributes be referred save to the Almighty, first cause of all things by whatever this name has been designated--the Divine Mind by Aristotle; the Soul of the Universe by Plato; the Natura Naturans by others; Saturn and Jove by the Gentiles; by ourselves, as is seemly in these days, the Creator and Father of all that is in heaven and earth, on whom all things depend for their being, and at whose will and pleasure all things are and were engendered." He thus opened his lectures in a broad spirit of religious charity quite foreign to his environment but befitting the position he has been called upon to occupy in the history of science. These notes of Harvey's visceral lecture are of especial value to us though they are a mere skeleton of the course--a skeleton which he was accustomed to clothe with facts drawn from his own vast stores of observation, with the theories of all his great predecessors and with the most apposite illustrations. Fortunately they deal with the thorax and its contents so that they show us the exact point which he had reached in connection with his great discovery of the circulation of the blood and the true function of the heart. The notes therefore are interesting reading quite apart from the peculiarities of their style.
