THE BELATION OF THE LABOBATOBT TO 

 MEDICINE 1 



In addressing so representative a body- 

 as this association I can not but feel that I 

 am engaged almost in a work of superero- 

 gation when I presume to speak upon a 

 topic so familiar to you all. Despite this 

 feeling on my part, I am led to believe that 

 upon occasion an oft-told tale, if palatably 

 redressed, may prove appetizing enough: 

 I will venture an experiment. 



A careful perusal of the pages of the his- 

 tory of medicine plainly demonstrates the 

 long and tortuous path pursued from the 

 ages of earliest record down to relatively 

 recent times. We can see how at one time 

 the noble art was held in the clutches of 

 superstition, its acts governed by a deep- 

 rooted primal belief in demonology; at an- 

 other time religious doctrines dominated 

 and intimidated progress; and at other 

 periods metaphysical discussions held back 

 advance and even wrecked discoveries. 

 The history of this struggle onwards to- 

 wards the light of knowledge, marked as it 

 has been by errors and lapses, is fascina- 

 tingly punctuated by epoch-making con- 

 tributions here and there along the line 

 by an occasional genius or hard-headed 

 thinker. It is not to be doubted, however, 

 that had it not been for the wonderful 

 development of the sciences, the modern 

 status of medicine would have been held 

 back for an indefinite period. Our debt to 

 the pioneers in chemistry, physics and biol- 

 ogy, and to their successors down to the 

 present moment, is enormous, and we must
