1894.] President's Address. 43 



Sir George Buchanan himself, that this testimonial should take the 

 form of a medal, to be awarded periodically for work done in con- 

 nection with sanitary science, and that the Royal Society should be 

 asked to administer the testimonial f and under the following con- 

 ditions : 



1. The money collected, after paying expenses incurred, to be 

 devoted 



(a) To the foundation of a Gold Medal of the value as nearly as 

 may be of twenty guineas, with a portrait of Sir George 

 Buchanan on the one side and an appropriate design on the 

 other, to be awarded every three or five years in respect of 

 distinguished services to Hygienic Science or Practice, in the 

 direction either of original research or of professional, ad-

 (remaining after paying for the Medal and discharging the 

 incidental expenses) which has accumulated since the last

 The preparation of copy for a supplementary volume, which will
