334 SCIENCE PROGRESS. 



physics and anatomy, chemistry also became in his hands a 

 tool for the service of experimental biology. 



A record which, in pages preceding mine, Professor 

 Stirling furnishes of the work of the great physiologist, gives 

 the reader an enumeration of the discoveries and researches 

 of Carl Ludwig. In closing my sketch of the master I would 

 pay one more last tribute to his great personality. For us 

 who knew Ludwig in the grandeur of his patriarchal age, 

 " hero-worship " was no idle phrase. He was for us a sage 

 and a priest; he inspired us with warm- hearted admiration for 

 the wonders and beauties which nature willingly reveals when 

 asked with conscientiousness and assiduity ; he taught us 

 modesty by impressing upon us how little we knew and how 

 small our powers compared with those of creative nature,-. 

 But he did still more for us ; he, the great investigator of 

 animal life, never forgot its higher, ethical aspects ; without 

 any ostentation or pretentious moralising he tried to imbue 

 us with the feeling that knowledge of life, as he understood 

 it, leads to the recognition of a path of duty and of stern 

 ideals. I have read or heard scarcely anything that could 

 vie, for instance, with the simple but beautiful words he 

 spoke to us all once suddenly, when lecturing on pain : 

 " Der Schmerz ist vielleicht das einzige Reale, was es auf 

 der Welt giebt. Alle Cultur gcht darauf aus, das zu be- 

 seitigen, was Schmerz verursacht, und die /where Cultur ist 

 bestrebt das zu beseitigen, was atich nur in der V or st el- 

 lung Schmerz er wee ken Konnte"
