PROF. HENRY CARVILL LEWIS AND HIS WORK 
IN GLACIAL GEOLOGY. 
By Warren Upham.* 
Henry Carvill Lewis, son of F, Mortimer Lewis and Emma 
Hulme (Carvill) Lewis, was born in Philadelphia on November 
16th, 1853. He graduated at the University of Pennsylvania 
in 1878, with the highest honors in the classical course; after 
which he took a post-graduate course of three years in the 
natural sciences, receiving the M. A. degree in 1870. From 
1879 to 1884 he was a volunteer member of the Geological Sur- 
vey of Pennsylvania, investigating at first the surf nee geology 
of the southern part of the state, and afterward tracing the 
terminal moraine of the continental ice-sheet across northern 
Pennsylvania. 
In 1880 he was elected to the professorship of mineralogy in 
the Academy of Natural Sciences, Philadelphia, and in 1883 to 
that of geology in Haverford College, both of which he held at 
the time of his death. 
In 1882 he married Miss Julia C. Foulke,of Philadelphia, who, 
with a daughter, survives him and will endeavor to complete 
and publish portions of his unfinished work on the glacial drift 
in Great Britain. 
From 1885 to 1887 professor Lewis was occupied during the 
winters in petrologic studies in Heidelberg with Prof. Rosen- 
busch, and during the summers in field-work on the glacial 
geology of England, Wales, Ireland, Switzerland, and northern
