Obituary. 



Henry Carvill Lewis. — Professor Lewis, of Philadelphia, 

 died at Manchester, England, on the 21st of July in his thirty- 

 fifth year. He was a graduate of the University of Pennsylvania, 

 an active member of the Academy of Sciences of Philadelphia, 

 and in 1883 became Professor of Geology in Haverford College. 

 One of his earliest papers, if not the first, is a notice of the Zodi- 

 acal Light, giving the results of five years' observations ; it was 

 read before the American Association in 1880, and appeared in 

 vol. xx (1880) of this Journal. He commenced his glacial inves- 

 tigations in 18*79, in connection with the Geological Survey of 

 Pennsylvania, worked on the same subject in 1885 and 1886 in 

 Great Britain, and had intended to make observations the present 

 season in Norway. The investigation of the " Terminal Moraine" 

 from the eastern boundary of Pennsylvania (to which point it 

 had been traced across New Jersey, by Professor G. H. Cooke), 

 westward across Pennsylyvania, occupied him until the autumn 

 of 1882, when his report of about 300 pages was presented for 

 publication. Jt appeared in 1884, as No. Z of the Geological 

 Series of the Pennsylvania Survey. In 1886 he read his paper on 

 Glaciation in Great Britain before the British Association. 



Professor Lewis was also a zealous mineralogist, and until 

 recently had editorial charge of the mineralogical department of 

 the American Naturalist. In 1886 he brought out his paper on 

 the " Genesis of the Diamond," tracing it to eruptive rocks, and 

 basing his views principally on the published accounts of the 

 diamond fields of Southern Africa. 



Mr. Lewis was an enthusiastic and energetic worker in Science, 

 and promised to do much for its progress. He leaves a wife and 

 one child. 



James Stevenson. — Col. Stevenson died on the 25th of July. 

 He was born in 1840, at Maysville, Kentucky. He was an early 

 explorer of the Rocky Mountain region, and accompanied Dr. 

 Hayden in his expedition as executive officer and manager. In 

 1872 he ascended the highest of the Teton Range, the Great 

 Teton. He has been, since 1879, connected with the U. S. Geologi- 

 cal Survey, engaged in making ethnological investigations and col- 

 lections in New Mexico and Arizona. A very valuable report 

 by him on the collections obtained in 1879 and 1880 is contained 

 in the Report of the Secretary of the Smithsonian Institution Tor 

 1881. 



Albert D. Hager. — Mr. Hager was associated with Professor 

 Edward Hitchcock and Mr. C. H. Hitchcock in the Geological 

 Survey of Vermont- Since 1872 he has lived in Chicago, where 

 he died on the 29th of July. He was born at Chester, Vermont, 

 in 1817.
