158 DR. BENJAMIN ALLEN, OF BRAINTREE. Allen (now in or about his sixtieth year) began to write his "Common-Place Book," already alluded to many times. Allen's Common-Place Book is a large post-folio volume (15ins. by 91/2ins. trimmed), substantially bound in contemporary vellum and containing [5] + 362 pages, nearly all closely written upon, though a few are blank. The title-page is inscribed :— Conclusions in several Subjects (as Anatomy, Medicin, Nature, Problems of the State, and Accidents of the World), containing the Discoverys in Summ upon the Prosecutions and Inquirys made ; By Benjamin Allen, Batchellour of Physick or Medicin, formerly of Queen's Colledge, in Cambridge : Anno 1723. Below are some moral reflections on the value of industry. On the back of the title-page is an index to the subjects discussed. Among the subjects dealt with in Allen's notes, that of medicine naturally takes the leading place and occupies most space. I deal with it first, though admitting my incompetence to treat it anything like adequately. I suggest that Allen's book is worth the serious attention of some student of the history of medicine in this country. At the very commencement, we meet with nearly fifty closely-written pages (1-47) filled with very detailed notes on various diseases, the remedies he had tried for the cure of them, and the results he secured thereby, together with a special index. Closely following this come more than fifty pages (51-102) devoted to "An Idaea of a Rational Anatomy." In it, Allen takes the various parts of the body—the lungs, the heart, the brain, the liver, the kidneys, the eye, the generative organs, &c.— and discusses each in great detail. The treatise looks much as though it were the first draft of an elaborate original work on the subject, intended ultimately for publication. Possibly, however, it is no more than a compilation from works previously published. In any case, it appears to be unfinished. Later, we have over sixty pages (113-174) devoted to "More Rare and Notable Medicinal Observations," detailing the results of his treatment of a great many particular cases. These notes and the earlier ones of the same kind make it perfectly clear that Allen was an exceedingly careful and observant physician—far more so, probably, than the average country practitioner of his day. Yet some of the remedies he used seem to us now to be exceedingly childish. Thus, he tells us (p. 114) how "Mr.
