xlviii PROCEEDiisros of the GEOLoaiCAL SOCIETY, [vol. Ixxviii, 



In 1887 Dr. Waclswortli became President of the Michigan 

 School o£ Mines, which was then in its infancy. He added to its 

 equipment, organized courses of instruction, and made it in five 

 years the greatest institution of its kind in the United States. 

 From this time onwards lie devoted himself mainly to adminis- 

 tiative and teaching work. In 1907 he was appointed Dean of the 

 School of Mines in Pittsburgh Universit}^, retiring in 1912 under 

 the age limit. His services were much appreciated by the Facult}^^ 

 and at the time of his death, which occurred on April 21st, 1921, 

 he was Dean Emeritus, Professor of Mining Geolog}^, and Emeritus 

 Curator of Geological and Mineralogical Collections in that Uni- 

 versity. He was elected a Fellow of our Society in 1889. 



[J. J. H. T.] 



Feederic Richard Mallet, son of Robert Mallet, himself a 

 distinguished member of our Society, joined the Geological Survey 

 of India in February 1859. In his earlier j^ears on the Survey he 

 had a varied experience of field-work in the Himalayas, Central 

 India, Assam, and Burma, but from 1876 until his retirement in 

 1889 was almost continuously in charge of the Museum and 

 Laboratory of the Department. He was the author of numerous 

 published contributions to our knowledge of geology, of which the 

 most important were probably his Memoir on the Vindhyan 

 System and his masterly description of the dormant Volcano 

 of Barren Island in the Bay of Bengal; but not less valuable 

 than his published papers, though less apparent, was the large 

 amount of careful work which he devoted to the maintenance 

 of the Surve}^ collections and to the assistance of other members 

 of the staff. Possessed in an eminent degree of precision and 

 neatness of method, a retiring disposition, covering a consistent 

 application to and thoroughness in his work, and an unfailing 

 courtesy and kindliness of demeanour, he was always ready to help 

 his fellow- workers in their difficulties, and Avon the attachment and 

 esteem of all who came in contact with him. After his retirement 

 from the Geological Survey of India he published little, but con- 

 tinued to devote himself to the pursuit of his favourite subject 

 until advancing ^^ears deprived him of the power of continuing to 

 work in his laboratory. He was elected into the Society in 1868, 

 and passed away on June 24th of last year in the 81st year of 

 his age.
