Obituary—Prof. Henry Carvill Lewis. 429 
born in Philadelphia, November 16th, 1853, being the son of Mr. 
F. Mortimer Lewis and Emma Hulme (Carvill) Lewis, of that city. 
At the age of 20 he graduated B.A. with first honours in Classics 
at the University of Pennsylvania, taking his M.A. degree in 1876. 
He took a post-graduate course of three years in Natural Science, 
and between 1879 and 1884 he served as a volunteer on the staff of 
the Geological Survey of Pennsylvania; investigating at first the 
surface-geology of Southern Pennsylvania, and afterwards the Glacial 
phenomena of the Northern part of that State. Here he succesfully 
traced the great terminal moraine of the North American Ice-sheet 
from New Jersey to the frontier of Ohio. During this period he 
contributed a number of papers to the Academy of Natural Sciences 
of Philadelphia upon the mineralogy and geology of Pennsylvania. 
In 1880 he was elected Professor of Mineralogy in the Academy 
of Natural Sciences, Philadelphia, and in 1883 he was appointed 
Professor of Geology in Haverford College, Pennsylvania, U.S. 
In 1882 Prof. Carvill Lewis married Miss Julia C. Foulke, daughter 
of the late Mr. W. Parker Foulke of Philadelphia, a man of varied 
attainments and wide scientific interests. 
Between 1885 and 1888 he was engaged in studies and original 
investigations in Kurope; the winters being spent in Heidelberg, 
where he worked at microscopic petrology and crystallography, 
under the guidance of Prof. Rosenbusch, and the summers in the 
field tracing out the difficult and complex problems connected with 
the Glacial ‘Epoch i in Great Britain and on the Continent. 
Here he had completed a map of the ancient glaciers and ice- sheets 
of England, Wales and Ireland, which was exhibited and discussed 
at the British Association, Birmingham, 1886; Manchester, 1887 ; 
and elsewhere. 
He had also commenced similar studies in Switzerland and North 
Germany. ‘These, however, were interrupted by a visit to America, 
where he contracted typhoid fever, which developed in a sudden 
and alarming manner immediately on his return to England, and 
terminated fatally on July 21st, at Manchester. 
Prof. Carvill Lewis was a Fellow of the Geological Society of 
London; of the Geological Society of Germany; a Member of the 
American Philosophical Society ; of the Academy of Natural Sciences 
of Philadelphia; the Franklin Institute; the American Association ; 
a Corresponding Member of the British Association ; and a Member 
of the Geological Society of Liverpool. 
It is always sad to see a bright young life suddenly cut short in 
early manhood, but it is more especially so when, as in the case of . 
Prof. Carvill Lewis, such good work had been already done, and we 
had abundant promise of a splendid future scientific career. 
Over and above all this Prof. Lewis had such a happy, bright and 
genial manner, that he readily won for himself the warm regard of a 
very wide circle of friends, whilst among men of science he seemed 
to give sure promise of a long life of solid and valuable work. 
His loss will be keenly felt both in America and Europe, not only 
amongst geologists, but men of science generally.
