44(1 Anniversary Meeting. [Dec. 1, 



It now only remains for me to thank the Fellows and others con- 

 vrvsant with the subjects on which I have touched, for information 

 kindly afforded me ; to thank you for the attention with which you 

 have listened to me, and to express a hope that it may not again for 

 many years occur that the Anniversary Address from this Presidential 

 chair shall have to be delivered by deputy. 



The Vice-President in the Chair then proceeded to the presentation 

 of the medals. 



The Copley Medal has been awarded to Professor Carl Ludwig, of 

 Leipzig, for his investigations in Physiology, and the great services 

 which he has rendered to Physiological Science. During the last 

 forty years, the advances that have been made both in the 

 powers of the microscope and in the methods of exact physical and 

 chemical observation have reacted in a remarkable manner on the 

 development of physiological knowledge, and during nearly the whole 

 of that long period the name of Carl Ludwig has been prominent 

 on the list of investigators, and to the progress that marks that 

 period he has probably contributed more than any man living. The 

 determination of the exact share in this progress really due to himself 

 nlone is perhaps somewhat obscured by the generous way in which he 

 has always placed his ideas and his knowledge at the service of those who 

 have assisted in his laboratory, bat there can be no doubt that a large 

 proportion of our present knowledge of the phenomena of blood 

 pressure and of the vaso-motor system, of the physiology of the 

 heart, and of the spinal cord, and of digestion and nutrition, is due 

 to him and to his numerous pupils. 



Moreover, the very fact that he has allowed so many others to 

 share in his experience and to become trained in his methods, 

 would in itself entitle him to some mark of our gratitude and 

 esteem. 



A Royal Medal has been awarded to Professor George H. Darwin 

 for his mathematical investigations on the effects of an imperfect 

 rigidity of the earth, and on tides. The principal results of these 

 researches have already been published in the " Philosophical Trans- 

 actions," and are in the hands of the Fellows, who will no doubt 

 rejoice to see the son of so distinguished a father still doing honour 

 to the name of Darwin. 



A Royal Medal has been awarded to Professor Daniel Oliver for 

 his investigations in the classification of plants, and the serv 

 which he has rendered to taxonomic Botany. These services have been 

 of the highest order ; but apart from his numerous published papers, 

 and his work on the Flora of Tropical Africa, his fertile labours in 

 tin- Kew Herbarium would alone entitle him to recognition at the
