  ADDRESS 
  OF 
  THE 
  PRESIDENT.

  hearted 
  earnest 
  worker, 
  and 
  I 
  well 
  remember, 
  when 
  I 
  was 
  studying 
  

   at 
  the 
  School 
  of 
  Mines, 
  how 
  ready 
  he 
  was 
  to 
  afford 
  any 
  of 
  us 
  

   assistance. 
  

  

  One 
  of 
  the 
  greatest 
  losses 
  that 
  the 
  Society 
  has 
  sustained 
  in 
  1888 
  

   is 
  caused 
  by 
  the 
  death, 
  at 
  the 
  early 
  age 
  of 
  34, 
  of 
  Henry 
  Carvill 
  

   Lewis. 
  He 
  was 
  born 
  in 
  Philadelphia, 
  U.S.A., 
  on 
  November 
  16th, 
  

   1853, 
  and 
  graduated 
  at 
  the 
  University 
  of 
  Pennsylvania 
  in 
  1873. 
  

   He 
  remained 
  in 
  the 
  University, 
  studying 
  Natural 
  History, 
  for 
  three 
  

   years 
  after 
  taking 
  his 
  M.A. 
  degree 
  in 
  1876, 
  and 
  from 
  1879 
  till 
  1884 
  

   served 
  as 
  a 
  volunteer 
  on 
  the 
  staff 
  of 
  the 
  Geological 
  Survey 
  of 
  Penn- 
  

   sylvania 
  under 
  Professor 
  Lesley. 
  In 
  1880 
  he 
  was 
  elected 
  Professor 
  

   of 
  Mineralogy 
  in 
  the 
  Academy 
  of 
  Natural 
  Sciences, 
  Philadelphia, 
  

   and 
  in 
  1883 
  he 
  was 
  appointed, 
  in 
  addition, 
  Professor 
  of 
  Geology 
  in 
  

   Haverford 
  College, 
  Pennsylvania. 
  He 
  held 
  both 
  appointments 
  until 
  

   his 
  death. 
  

  

  The 
  question 
  to 
  which 
  Professor 
  Carvill 
  Lewis's 
  attention 
  was 
  

   especially 
  devoted, 
  whilst 
  engaged 
  on 
  the 
  staff 
  of 
  the 
  Pennsylvanian 
  

   Geological 
  Survey, 
  was 
  the 
  delimitation, 
  within 
  the 
  State 
  of 
  Penn- 
  

   sylvania, 
  of 
  the 
  old 
  ice-sheet 
  that 
  covered 
  so 
  large 
  a 
  portion 
  of 
  

   North 
  America 
  in 
  the 
  Glacial 
  period, 
  and 
  the 
  mapping 
  of 
  the 
  

   terminal 
  moraine. 
  To 
  this 
  work 
  some 
  other 
  members 
  of 
  the 
  Geo- 
  

   logical 
  Survey 
  contributed, 
  and 
  important 
  assistance 
  was 
  given 
  by 
  

   another 
  volunteer, 
  the 
  Eev. 
  G. 
  P. 
  Wright. 
  But 
  the 
  principal 
  field- 
  

   observations 
  were 
  made 
  by 
  Professor 
  Carvill 
  Lewis 
  himself, 
  and 
  

   the 
  " 
  Report 
  on 
  the 
  Terminal 
  Moraine 
  in 
  Pennsylvania 
  and 
  New 
  

   York," 
  published 
  in 
  1884, 
  is 
  entirely 
  written 
  by 
  him. 
  It 
  is 
  the 
  

   most 
  important 
  work 
  of 
  which 
  he 
  was 
  the 
  author, 
  and 
  contains 
  a 
  

   mass 
  of 
  information 
  not 
  only 
  concerning 
  the 
  limits 
  of 
  the 
  North- 
  

   American 
  ice-sheet, 
  but 
  also 
  regarding 
  its 
  action 
  and 
  effects 
  within 
  

   those 
  limits. 
  

  

  In 
  1885 
  Professor 
  Carvill 
  Lewis 
  came 
  to 
  Europe, 
  and 
  from 
  that 
  

   year 
  till 
  his 
  untimely 
  death 
  was 
  engaged 
  during 
  the 
  summers 
  in 
  

   applying 
  to 
  England, 
  Ireland, 
  and 
  portions 
  of 
  Germany 
  and 
  Switzer- 
  

   land 
  the 
  observations 
  made 
  on 
  the 
  evidence 
  of 
  ice-action 
  in 
  Penn- 
  

   sylvania, 
  and 
  during 
  the 
  winters 
  in 
  studying 
  petrology 
  with 
  Prof. 
  

   Rosenbusch 
  at 
  Heidelberg. 
  Some 
  of 
  the 
  results 
  of 
  Prof. 
  Lewis's 
  

   observations 
  on 
  the 
  glacial 
  phenomena 
  of 
  Great 
  Britain 
  and 
  Ireland 
  

   were 
  presented 
  to 
  the 
  British 
  Association 
  in 
  1886 
  and 
  1887 
  ; 
  but 
  

   as 
  there 
  were 
  still 
  several 
  points 
  on 
  which 
  he 
  wished 
  for 
  further 
  in- 
  

   formation, 
  no 
  complete 
  account 
  of 
  his 
  views 
  was 
  published.
