night by one of the members, in rotation. Most of the distinguishing features of the philosophical systems of Gregory and his colleagues, who have been already mentioned, were first delivered in this society. Gregory's work on the faculties of man and other animals, was first composed as essays for the Wise Club, but afterwards arranged and published under the patronage of his friend lord Lyttleton—the first instance in which Gregory appeared to the world as an author. This work, which was published in London, 1764, was entitled, "A Comparative View of the State and Faculties of Man, with those of the animal world."
Dr Gregory remained in the chair of medicine in Aberdeen for eight years, when, with a view to the increase of his practice, he removed to Edinburgh, and two years afterwards was appointed successor to Dr Rutherford in the university there, as professor of the practice of physic, and in the same year, 1766, he succeeded Dr Whyt as first physician to his majesty in Scotland. Dr Gregory lectured for three years solely on the practice of physic; but at that time an agreement was entered into by his honoured colleague Dr Cullen—the celebrated author of the system of Nosology which goes by his name—that they should lecture in turn on the theory and practice of medicine, which was continued for many years. None of Dr Gregory's lectures were ever written, except a few introductory ones on the duties and qualifications of a physician; which probably would not have made their appearance, had it not been the circumstance of one of his students offering a written copy, taken from notes, to a bookseller for sale, which induced Gregory to publish the work, the profits of which he gave to a poor and deserving student. This will always be a standard work among medical men, and will ever remain a lasting monument of the author's profound research, energy of mind, and liberality of opinion. Nothing could so effectually convince us, as the perusal of this work, of the truth of one of his observations—"that the profession of medicine requires a more comprehensive mind than any other." This work was published in 1770, and the same year he published his Elements of the Practice of Physic, a work which was intended as a text book for his pupils, and was excellent as far as it went, but never was completed.
The amiable and accomplished wife of Dr Gregory lived only with him nine years, during which period he enjoyed all the pleasure which domestic happiness could afford. He regretted her death exceedingly; and, as he says himself, he, for the amusement of his solitary hours, wrote that inimitable little work—"A Father's Legacy to his Daughters." In this work he feelingly states, that while he endeavours to point out to them what they should be, he draws but a very faint and imperfect picture of what their mother was.
Gregory inherited from his mother a disease, with which he had from the age of eighteen been frequently attacked. This was the gout, of which his mother died suddenly while sitting at table. The doctor often spoke of this to his friends, and one day when talking with Dr James Gregory, his son (author of the Conspectus Theoreticæ Medicinæ), it was observed by the latter, that as he had not had an attack these three years past, it was likely the next would be pretty severe. Dr Gregory was not pleased with this remark of his son, but unfortunately the prediction was true. Dr Gregory had gone to bed in his usual health on the 9th of February, 1773, and seems to have died in his sleep, as he was found in the morning without the slightest appearance of discomposure of feature or limb. Dr Beattie laments him pathetically in the concluding stanzas of the Minstrel:—
Art thou, my Gregory, for ever fled,
And am I left to unavailing woe;
