560 PROCEEDINGS OF THE PHILADELPHIA MEETING 



which those best acquainted with Professor Pettee always expect in papers 

 prepared by his hand. 



The annual Transactions of the American Institute of Mining Engineers 

 have been submitted to Professor Pettee for many years for critical proof- 

 reading and correction. Of that society he was a life member, his election 

 dating from 1871. For many years he was a coworker with its secretary, 

 Rossiter W. Raymond, who, in a recent memorial published in the Trans- 

 actions of the Institute, expressed high appreciation of Professor Pettee's 

 ability as a literary critic. He was one of the original fellows of the Geo- 

 logical Society of America, a fellow of the American Association for the 

 Advancement of Science, in which he was general secretary in 1887 ; a 

 member of the American Academy of Arts and Sciences during his resi- 

 dence in Massachusetts, and a member of the American Philosophical 

 Society of Philadelphia. 



For Professor Pettee the members of the faculty of the University of 

 Michigan, of which he was a member for twenty-nine years, hold only 

 memories of the highest respect and the warmest friendship. These cher- 

 ished sentiments are but a reflection of his own genial and loving nature, 

 left by him as an inheritance to all with whom he came in contact. His 

 more pronounced characteristics as revealed in his intercourse with his 

 colleagues, whether personally and socially or in connection with official 

 duties, and equally conspicuous to the students who received his instruc- 

 tion, were a kindly and loving nature, patience under difficulties, pains- 

 taking accuracy in all of his work, love of truth, and unswerving upright- 

 ness of character. With these high ideals were coupled an abundant and 

 ever accessible knowledge of the history and traditions of education in 

 Michigan and a love for the branches of science to which he devoted his 

 time and energy. 



Professor Pettee died at his home in Ann Arbor, Michigan, on May 26, 

 1904. While his chief work during life was that of a teacher, his few con- 

 tributions to geology and kindred subjects show that he was a painstaking 

 and accurate observer.
