BRITISH ASSOCIATION FOR THE ADVANCE- 

 MENT OF SCIENCE.* 

 ADDRESS BY THE PRESIDENT. 

 My Lord Mayor, my Lords, Ladies and 

 Gentlemen, I have first to express my deep 

 sense of gratitude for the great honor con- 

 ferred upon .me by my election to the high 

 office which I occupy to-day. It came upon 

 me as a great surprise. The engrossing 

 claims of surgerj^ have prevented me for 

 many years from attending the meetings of 

 the Association, which excludes from her 

 sections medicine in all its branches. This 

 severance of the art of healing from the 

 work of the Association was right and in- 

 deed inevitable. Not that medicine has lit- 

 tle in common with science. The surgeon 

 never performs an operation without the 

 aid of anatomy and physiology ; and in 

 what is often the most difficult part of his 

 duty, the selection of the right course to 

 follow, he, like the physician, is guided 

 by pathology, the science of the nature 

 of disease, which, though very difficult 

 from the complexity of its subject-mat- 

 ter, has made during the last half-cen- 

 tury astonishing progress ; so that the 

 practice of medicine in every depart- 

 ment is becoming more and more based 

 on science as distinguished from empiri- 

 cism. I propose on the present occasion to 

 bring before you some illustrations of the 



* Liverpool meeting, beginning September 16, 

 1896.
