THE INFLUENCE OF SIR WILLIAM HENRY 



PE REIN'S DISCOVERY UPON OUR 



SCIENCE} 



I NEED hardly assure you how highly 

 honored I feel to be permitted to speak 

 here to-night. Yet I am fully aware that 

 the committee did not select me because 

 it considered me the most competent of our 

 chemists to respond to this subject, but 

 because so many of our colleagues refused 

 to be heard, fearing the arduous labor of 

 condensing this vast material within the 

 limits of a fifteen-minute address, when 

 fifteen hours could be devoted to it with 

 much less difficulty and work. With me, 

 however, it was a labor of love, and I ac- 

 cepted with pride and pleasure, inspired 

 by the wonderful development of this in- 

 dustry in which I have been an attentive 

 watcher and a modest coworker, it being 

 just twenty years since, in collaboration 

 with Professor Bernthsen, I began the in- 

 vestigations which finally culminated in the 

 discovery of the constitution of the dye- 

 stuffs of the safranine series. Above all, 

 I have been inspired in my task by the 

 genial personality and refined modesty of 

 our distinguished guest, Sir William 

 Henry Perkin, with whom I had the pleas- 

 ure of becoming more intimately ac- 

 quainted during last year's meeting of the 

 Society of Chemical Industry in London. 

 It must be a sincere source of congratula-
