fixed convictions and practices may be better understood from the fact that so little difference did he make between his patients that he kept Peter the Great waiting over one night to see him, declining to regulate his visiting list by the means or position of his patients. Boerhaave was universally regarded as a great student and a great physician, but it was probably his qualities as a man which led to the astonishing extent of his reputation. Essentially modest, not disputatious nor belligerent, he had a remarkable influence over the young men who came near him, while he had a habit of speaking oracularly or in aphorisms, which are not always so profound as they sound and yet often make a man's dicta celebrated. Save that he introduced the use of the thermometer and the ordinary lens in the examinations of his patients, his teachings do not form any really new system. In the classification of men he would be regarded as a great eclectic, in the purer sense of the term. Probably his greatest service to medicine was in the permanent establishment of the clinical method of instruction, and perhaps his next greatest real claim to glory is the character of the instruction and the inspiration which he gave to two of his greatest scholars, viz.: Haller and Van Swieten. He was not the founder of a school. He left no great nor memorable doctrines for which others should contend, but he left a name for studiousness, honest and logical thinking, which was a priceless heritage for the university with which he was connected. The next great scholar to whose life and works I would invite your attention for a moment, is Morgagni, born in Italy in 1682, died in 1772. He was a pupil of Valsalva, whose assistant he became at the age of nineteen. Brought up in this way, as it were in the domain of anatomy, it is not strange that he devoted his attention throughout his life especially to the anatomical products of disease. It matters little to us now that he was wont to regard these products as the causes of disease and thus neglected their remote causes. He it was who taught us to apply to pathological anatomy the same scrupulous attention to tissue alterations and changes which the ordinary anatomist would note in dissecting a new animal form. He was scarcely the founder of the science of pathological anatomy, for this credit belongs to Benivieni, but he did very much to popularize the study and to show its importance. More than this, he wrote a work which for his day and generation was colossal. It bore the title "_De Sedibus et Causis Morborum per Anatomen Indagatis._" It consisted of five books. The first appeared in Venice in 1761. This proved a perfect mine of information to which one may often turn even to-day, and read with wonder the observations published one hundred and fifty years ago. They stamp Morgagni as a great scientist as well as anatomist. His industry will be indicated by the fact that even after he became blind he did not cease to work.
