This volume of mine was one of those which were not fated to dwell among "Persons of Honour and Quality" in old England; it crossed the waters to the new land with simpler folk, and was for many years the pocket-companion of an old New England doctor. Two names are carefully written on the inside of the cover of my book, names of past owners: "Edward Talbot, His Book," is in the most faded ink, and "William Morse, His Book, in the y'r 1710, Boston." A musty, leathery smell pervades and exhales from the pages, and is mingled with whiffs of an equally ancient and more penetrating odor, that of old drugs and medicines; for many a journey over bleak hills and lonely dales has the book made, safely reposing at the bottom of its owner's pocket, or lying cheek by jowl with the box of drugs and medicines, and case of lancets in his ample saddlebags. This country doctor, like others of his profession at the same date, had not studied deeply in college and hospital; nor had he taken any long course of instruction in foreign schools and universities. When he had decided to become a doctor, he had simply ridden with an old, established physician--ridden literally--in a half-menial, half-medical capacity. He had cared for the doctor's horse, swept the doctor's office, run the doctor's errands, pounded drugs, gathered herbs, and mixed plasters, until he was fitted to ride for himself. Then he had applied to the court and received a license to practise--that was all. I doubt not that this book of mine, and perhaps a manuscript collection of recipes and prescriptions, and a few Latin treatises that he could hardly decipher, formed his entire pharmacop[oe]ia. As he had chanced to inherit a small fortune from a relative, he became a physician of some note; for in colonial days wealth and position were as essential as were learning and experience, to enable one to become a good doctor.
