1911.] Anniversary Address by Sir A. Geikie. 



437 



he^has been engaged on a series of elaborate researches into the conditions in 

 which deposits from saline solutions can be formed in the sea. His papers on 

 this subject throw fresh light on the history of accumulations of this nature 

 which are intercalated among the strata of the earth's crust, and his work is 

 thus of interest alike to the chemist and the geologist. 



On the side of the biological sciences, six of our Fellows have died 

 during the past year. The cause of research in tropical medicine has 

 suffered a grievous loss by the premature death of Sir Hubert Boyce. 

 His career of only forty -eight years has been marked by unwearied energy 

 and enthusiasm in the contest with the malignant diseases that are the 

 scourge of man in tropical climates. Not merely did he personally carry 

 on researches in this country and encourage others to co-operate in the 

 same cause, but, throwing himself into the breach, he again and again 

 sailed to the Tropics for the purpose of enquiring into the maladies on the 

 spot. His labours, and those of the other investigators who have studied 

 yellow fever, have been rewarded, and now that fatal malady has been 

 successfully combated. 



Of the physicians on the list of our Fellows we have to record the deaths 

 of three eminent men. John Hughlikgs Jackson was the founder of the 

 modern school of neurology in this country. Perhaps his greatest work 

 was his discovery, on purely clinical grounds, of the localisation of function 

 in the centre of the brain — a discovery that has been verified and greatly 

 extended by a long series of experimental researches by other observers. 



Frederick William Pavy, for so many years a familiar figure at our 

 meetings, has passed away in his eighty-third year. He has held a high 

 place among the physicians of his day, not only as an eminent practitioner, 

 but as an accomplished and assiduous man of science, who devoted his long 

 life mainly to one special branch of investigation — the part played by sugar 

 in the economy of the animal system. The important bearing of his 

 investigations on diabetes and other diseases has long been recognised both 

 in this country and abroad. 



Sir Samuel Wilks was remarkable for the keen insight shown in his 

 recognition of the fact that medicine must rest on the science of pathology. 

 He devoted his life and teaching to the development of this principle. His 

 contributions to pathological knowledge were many and valuable in them- 

 selves, but they acquired additional importance from the correlation which 

 he established between the findings of pathology and of morbid anatomy 

 on the one hand, and the natural history of disease, as seen clinically, on the 

 other. To the end of his life he took the greatest and most appreciative 

 interest in the new and striking developments of his own favourite science.
