Samuel Lewis Penfield. 361 



ence, a Corresponding Member of the Royal Society of Sciences 

 at Gottingen, Germany, and member of the Scientific Society 

 of Christiania, Norway : in 1903 he was elected Corresponding 

 Member of the Geological Society of Stockholm and Foreign 

 Member of the Mineralogical Society of Great Britain : in 1904 

 the University of Wisconsin conferred upon him the degree of 

 Doctor of Laws. He was also a member of the Connecticut 

 Academy of Arts and Sciences and a Fellow of the Geological 

 Society of America. 



As a teacher Penfield was a striking example of what may 

 be accomplished by an intelligent and painstaking devotion of 

 one's effort toward a given end. He w T as not naturally gifted 

 as a teacher — as a lecturer and speaker — as some men are. Of 

 an extremely modest, quiet and retiring disposition and some- 

 what reserved except among his intimate friends, he always 

 found it difficult, and naturally disliked, to express himself in 

 public. Thus at the outset the management and instruction of 

 students in numbers was for him not an easy matter. But he 

 so entirely overcame this and perfected to so great a degree his 

 methods of teaching, that the many students who came under 

 his instruction regarded him as one of the best teachers in the 

 University. In laboratory work, where the contact with the 

 student is personal, he always had great success from the begin- 

 ning of his career, because, in his kindliness of disposition, great 

 patience and persistency, and in his interest in the student and 

 his work, he had natural aptitudes which specially fitted him 

 for this kind of instruction, and he took morever distinct pleas- 

 ure in it. He always insisted upon great thoroughness and 

 completeness in allotted work, and the mental discipline and 

 training in method which students received under him were nofc 

 less valuable than the knowledge of mineralogy which they 

 acquired. 



With those who- came under him for advanced instruction he 

 was particularly fortunate. The untiring care and oversight 

 which he gave to their work and the thoroughness and accuracy 

 upon which he insisted gave almost invariably successful results, 

 and thus, especially in research, he communicatedliis own energy 

 and enthusiasm to his pupils and stimulated their interest. 

 This is clearly shown in the large number of important pieces
