He remained at the King's School for five years, no doubt coming home for the holidays, some of which must have been spent in watching the constant transport of troops to Spain and Portugal which was so noticeable a feature in the history of the Cinque Ports during the later years of the life of Elizabeth.
His schooling ended, Harvey entered at once as a pensioner, or ordinary student, at Caius College, Cambridge, his surety being George Estey. The record of his entry still exists in the books of the College. It runs: "Gul. Harvey, Filius Thomae Harvey, Yeoman Cantianus, ex oppido Folkeston, educatus in Ludo Literario Cantuar. natus annos 16, admissus pensionarius minor in commeatum scholarium, ultimo die Mai 1593." (William Harvey, the son of Thomas Harvey, a yeoman of Kent, of the town of Folkestone, educated at the Canterbury Grammar School, aged 16 years, was admitted a lesser pensioner at the scholars' table on the last day of May, 1593.)
The choice of the college seems to show that Harvey was already destined by his father to follow the medical profession. His habits of minute observation, his fondness for dissection and his love of comparative anatomy had probably shown the bias of his mind from his earliest years. Thirty-six years before Harvey's entry, Gonville Hall had been refounded as Gonville and Caius College, Cambridge, by Dr. Caius, who was long its master. Caius, in addition to his knowledge of Greek, may be said to have introduced the study of practical anatomy into England. His influence obtained for the college the grant of a charter in the sixth year of the reign of Queen Elizabeth, a charter by which the Master and Fellows were allowed to take annually the bodies of two criminals condemned to death and executed in Cambridge or its Castle free of all charges, to be used for the purposes of dissection, with a view to the increase of the knowledge of medicine and to benefit the health of her Majesty's lieges, without interference on the part of any of her officials. Unfortunately no record has been kept as to the use which the college made of this privilege, nor are there any means of ascertaining whether Harvey did more than follow the ordinary course pursued by students until he graduated as a Bachelor of Arts in 1597. His education, in all probability, had been wholly general thus far, consisting of a sound knowledge of Greek, a very thorough acquaintance with Latin, and some learning in dialectics and physics. He was now to begin his more strictly professional studies, and the year after he had taken his Arts degree at Cambridge found him travelling through France and Germany towards Italy, where he was to study the sciences more nearly akin to medicine, as well as medicine itself.
