Dr. Bohun sought medical supplies from abroad, but he also experimented with indigenous natural matter such as plants and earths in an effort to replenish his dwindling supplies and to discover natural products of value in the New World. Judging by a contemporary account, Bohun, professionally trained in the Netherlands, used drugs therapeutically according to the conventional theories of the humoral school. Despite the disfavor in which frequent purgings are held today, it must be allowed that those being treated then sounded a plaintive call for more of Bohun's "physicke."
The colony lost his services when he left to accompany Lord De la Warr to the West Indies. His connection with the London Company and its colony did not lapse, however, for Bohun received an appointment as physician-general for the colony in December, 1620. At sea, on the way to fill his post, the physician-general found his ship engaged with two Spanish men-of-war. In the course of battle, an enemy shot mortally wounded the man who had survived great hazards at Jamestown.
After the departure of Bohun with Lord De la Warr, no physician or surgeon of equal stature or reputation took up residence in Virginia until Dr. John Pott arrived almost ten years later. It is likely that there was a shortage not only of outstanding medical men during these years, but also of medical assistance in general. Sir Thomas Dale, acting as deputy governor in the absence of De la Warr, wrote in the spring of 1611 that "our wante likewise of able chirurgions is not a little." Other requests for physicians and for apothecaries were dispatched to the London Company during this period.
However, despite the seeming shortage of medical assistance, the colonists survived such disorders as the summer seasoning much more frequently than in the first years at Jamestown. An account of Virginia written between 1616 and 1618 noted of the settlers that:
They have fallen sick, yet have recovered agayne, by very small meanes, without helpe of fresh diet, or comfort of wholsome phisique, there being at the first but few phisique helpes, or skilful surgeons, who knew how to apply the right medecine in a new country, or to search the quality and constitution of the patient, and his distemper, or that knew how to councell, when to lett blood, or not, or in necessity to use a launce in that office at all.
Bohun died in March, 1621, and the Company named his successor as physician to the colony in July. The conditions under which Dr. John Pott accepted the post reveal the qualifications and needs of the seventeenth-century medical man on his way to the New World, and the inducements offered by the Company. He was a Cambridge Master of Arts and claimed much experience in the practice of surgery and "phisique." In addition, he made much of his expertness in the distilling of water. The company allowed Pott a chest of medical supplies, a small library of medical books, and provisions for the free passage of one or more surgeons if they could be secured.
Additional economic inducements helped persuade Pott—and other physicians—to make the arduous journey to America. In the eyes of the Company, physicians could render especially valuable services to the colony, and ranked with other persons of extraordinary talent such as ministers, governors, state officers, officers of justice, and knights. These individuals received special compensations in the form of land and profits, in accord with the estimated value of services to be rendered. In 1620, Dr. Bohun had had a promise—for taking the position of physician-general for the colony—of an allotment of 500 acres of land and ten servants; Pott accepted the job under about the same conditions as had Bohun.
These inducements offered physicians to persuade them to go to Virginia indicate the great need for, and the high value attached to, their assistance in the seventeenth century. With the population in the colony growing so great Dr. Pott's services were in considerable demand; several years after his arrival a certain William Bennett built the doctor a boat as he by then had a relatively large area to cover and most of the outlying plantations stood on the rivers and creeks.
In the colony, Pott won recognition for his professional proficiency. Even a political enemy, Governor Harvey, described him as skilled in the diagnosis and therapy of epidemic diseases. Because he alone in the colony was considered capable of treating epidemic diseases, a court sentence against him for cattle theft stood suspended early in the 1630's and clemency was sought on his behalf.
Pott had become involved in other legal difficulties before 1630. In 1625, a case having medical and humorous implications brought him into court. A Mrs. Blany maintained that Doctor Pott had denied her a piece of hog flesh, and that his refusal had caused her to miscarry. The court accepted Mrs. Blany's contention that she believed the denial of the hog flesh caused her distress, but did not hold Pott guilty of willful neglect.
