reet the rising of the sun of science。 What a contrast in their lives and in their works！ The great Dominican's long life was an uninterrupted triumph of fruitful accomplishmentthe titanic task he set himself was not only completed but was appreciated to the full by his own generation a life not only of study and teaching； but of practical piety。 As head of the order in Germany and Bishop of Regensburg； he had wide ecclesiastical influence； and in death he left a memory equalled only by one or two of his century； and excelled only by his great pupil； Thomas Aquinas。 There are many Alberts in history the Good； the Just； the Faithfulbut there is only one we call 〃Magnus〃 and he richly deserved the name。 What is his record？ Why do we hold his name in reverence today？
Albertus Magnus was an encyclopaedic student and author； who took all knowledge for his province。 His great work and his great ambition was to interpret Aristotle to his generation。 Before his day； the Stagirite was known only in part； but he put within the reach of his contemporaries the whole science of Aristotle； and imbibed no small part of his spirit。 He recognized the importance of the study of nature； even of testing it by way of experiment； and in the long years that had elapsed since Theophrastus no one else； except Dioscorides； had made so thorough a study of botany。 His paraphrases of the natural history books of Aristotle were immensely popular； and served as a basis for all subsequent studies。 Some of his medical works had an extraordinary vogue； particularly the 〃De Secretis Mulierum〃 and the 〃De Virtutibus Herbarum；〃 but there is some doubt as to the authorship of the first named； although Jammy and Borgnet include it in the collected editions of his works。 So fabulous was his learning that he was suspected of magic and comes in Naude's list of the wise men who have unjustly been reputed magicians。 Ferguson tells＇22＇ that 〃there is in actual circulation at the present time a chapbook。 。 。 containing charms； receipts； sympathetical and magicalcures for man and animals； 。 。 。 which passes under the name of Albertus。〃 But perhaps the greatest claim of Albertus to immortality is that he was the teacher and inspirer of Thomas Aquinas； the man who undertook the colossal task of fusing Aristotelian philosophy with Christian theology； and with such success that the 〃angelic doctor〃 remains today the supreme human authority of the Roman Catholic Church。

A man of much greater interest to us from the medical point of view is Roger Bacon and for two reasons。 More than any other mediaeval mind he saw the need of the study of nature by a new method。 The man who could write such a sentence as this： 〃Experimental science has three great prerogatives over other sciences； it verifies conclusions by direct experiment； it discovers truth which they never otherwise would reach； it investigates the course of nature and opens to us a knowledge of the past and of the future；〃 is mentally of our day and generation。 Bacon was born out of due time； and his contemporaries had little sympathy with his philosophy； and still less with his mechanical schemes and inventions。 From the days of the Greeks； no one had had so keen an appreciation of what experiment meant in the development of human knowledge； and he was obsessed with the idea； so commonplace to us； that knowledge should have its utility and its practical bearing。 〃His chief merit is that he was one of the first to point the way to original researchas opposed to the acceptance of an authoritythough he himself still lacked the means of pursuing this path consistently。 His inability to satisfy this impulse led to a sort of longing； which is expressed in the numerous passages in his works where he anticipates man's greater mastery over nature。〃＇23＇

Bacon wrote a number of medical treatises； most of which remain in manuscript。 His treatise on the 〃Cure of Old Age and the Preservation of Youth〃 was printed in English in 1683。＇24＇ His authorities were largely Arabian。 One of his manuscripts is 〃On the Bad Practices of Physicians。〃 On June 10； 1914； the eve of his birth； the septencentenary of Roger Bacon will be celebrated by Oxford； the university of which he is the most distinguished ornament。 His unpublished MSS。 in the Bodleian will be issued by the Clarendon Press ＇1915…1920＇； and it is hoped that his unpublished medical writings will be included。
＇24＇ It may be interesting to note the three causes to which he attributes old age： 〃As the World waxeth old； Men grow old with it： not by reason of the Age of the World； but because of the great Increase of living Creatures； which infect the very Air； that every way encompasseth us； and Through our Negligence in ordering our Lives； and That great Ignorance of the Properties which are in things conducing to Health； which might help a disordered way of Living； and might supply the defect of due Government。〃
What would have been its fate if the mind of Europe had been ready for Roger Bacon's ferment； and if men had turned to the profitable studies of physics； astronomy and chemistry instead of wasting centuries over the scholastic philosophy and the subtleties of Duns Scotus； Abelard and Thomas Aquinas？ Who can say？ Make no mistake about the quality of these mengiants in intellect； who have had their place in the evolution of the race； but from the standpoint of man struggling for the mastery of this world they are like the members of Swift's famous college 〃busy distilling sunshine from cucumbers。〃 I speak； of course； from the position of the natural man； who sees for his fellows more hope from the experiments of Roger Bacon than from the disputations of philosophy on the 〃Instants； Familiarities； Quiddities and Relations；〃 which so roused the scorn of Erasmus。
MEDIAEVAL MEDICAL STUDIES
IT will be of interest to know what studies were followed at a mediaeval university。 At Oxford； as at most of the continental universities； there were three degrees； those of Bachelor； Licentiate and Doctor。 The books read were the 〃Tegni〃 of Galen； the 〃Aphorisms〃 of Hippocrates； the 〃De Febribus〃 of Isaac and the 〃Antidotarium〃 of Nicolaus Salernitanus： if a graduate in arts； six years' study in all was required； in other faculties； eight。 One gets very full information on such matters from a most interesting book； 〃Une Chaire de Medecine au XVe Siecle；〃 by Dr。 Ferrari （Paris； 1899）。 The University of Pavia was founded in 1361； and like most of those in Italy was largely frequented by foreigners； who were arranged； as usual； according to their nationalities； but the students do not appear to have controlled the university quite so much as at Bologna。 The documents of the Ferrari family； on which the work is based； tell the story of one of its members； who was professor at Pavia from 1432 to 1472。 One is surprised at the range of studies in certain directions； and still more at the absence of other subjects。 A list is given of the teachers in medicine for the year 1433； twenty in all； and there were special lectures for the morning； afternoon and evening。 The subjects are medicine； practical medicine； physics； metaphysics； logic； astrology； surgery and rhetoric： very striking is the omission of anatomy； which does not appear in the list even in 1467。 The salaries paid were not large； so that most of the teachers must have been in practice： four hundred and five hundred florins was the maximum。
The dominance of the Arabians is striking。 In 1467； special lectures were given on the 〃Almansor〃 of Rhazes； and in the catalogue of the Ferrari's library more than one half of the books are Arabian commentaries on Greek medicine。 Still more striking evidence of their influence is found in the text…book of Ferrari； which was printed in 1471 and had been circulated earlier in MS。 In it Avicenna is quoted more than 3000 times； Rhazes and Galen 1000； Hippocrates only 140 times。 Professor Ferrari was a man who played an important role in the university； and had a large consultation practice。 You will be interested to know what sort of advice he gave in special cases。 I have the record of an elaborate consultation written in his own hand； from which one may gather what a formidable thing it was to fall into the hands of a mediaeval physician。 Signor John de Calabria had a digestive weakness of the stomach； and rheumatic cerebral disease； combined with superfluous heat and dryness of the liver and multiplication of choler。 There is first an elaborate discussion on diet and general mode of life； then he proceeds to draw up certain light medicines as a supplement； but it must have taken an extensive apothecary's shop to turn out the twenty…two prescriptions designed to meet every possible contingency。
One of the difficulties in the early days of the universities was to procure good MSS。 In the Paris Faculty； the records of which are the most complete in Europe； there is an inventory for the year 1395 which gives a list of twelve volumes； nearly all by Arabian authors。＇25＇ Franklin gives an interesting
