The empiric under the title of the practical man, in his unsuspecting ignorance, sets himself up and is admitted as arbiter wherever there is difficulty: blind himself, he leads the blinded multitude the way he lists. He who laid the foundation of modern medical science lost his practice for his pains, and the routineer, with an appropriate salve for every sore, a pill and potion for each particular ache and ail, would not give threepence for one of his prescriptions! did not admire his therapeutique way!! and could not tell what he did aim at!!! Ignorance and presumption have never hesitated to rend the veil that science and modesty, all in supplying the means, have still owned their inability to raise. If Harvey faltered, who of his contemporaries could rightfully presume to walk secure? And yet did each and all of them, unconscious of the darkness, tread their twilight paths assuredly; whilst he, the divinity among them, with his eyes unsealed, felt little certain of his way. So has it still been with medicine; and the world must make many a lusty onward stride in knowledge before it can be otherwise.
The first interruption to his ordinary professional pursuits and avocations which Harvey seems to have suffered through his connexion with the court, occurred in the beginning of 1630, when he was engaged "to accompany the young Duke of Lenox in his travels beyond seas." In anticipation of a removal from London, apparently, Harvey had already, in December 1629, resigned his office of treasurer to the College of Physicians, which he seems to have filled for several years.
Of the course of Harvey's travels with the Duke of Lenox we have not been able to gain any information. Their way probably led them to the Continent, and it may have been on this occasion and in this company that he visited Venice, as we know from himself that he did in the course of one of his journeys. Harvey must have been in England again in 1632 and 1633; for in the former year he was formally chosen physician
