Vol.  49.]  ANNIVERSARY  ADDRESS  OE  THE  PRESIDENT.  63 
River  on  the  expedition  under  Lieutenant  Ives.  The  party  as¬ 
cended  the  river  in  a  steamer  for  500  miles  from  its  month,  and 
brought  hack  grand  views  of  the  wonderful  scenery  of  the  canon, 
then  for  the  first  time  explored,  for  the  illustration  of  his  excellent 
Geological  Report,  as  well  as  for  that  of  the  Commander  of  the 
Expedition.  Again  in  1859  he  was  geologist  of  the  Government 
expedition  under  Captain  Macomb,  which  explored  the  country  of 
the  San  Juan  and  Upper  Colorado,  and  thus  had  an  opportunity  for 
the  geological  study  of  part  of  Utah,  Horthern  Arizona,  and  Hew 
Mexico.  His  report  appeared,  after  much  delay,  in  1876,  in  con¬ 
nexion  with  the  Report  of  an  Expedition  from  Santa  Fe  to  the 
junction  of  the  Grand  and  Green  Rivers.  The  volume  contains, 
besides  a  general  report  on  the  geology  of  the  regions  visited,  de¬ 
scriptions  by  F.  B.  Meek  of  his  Cretaceous  fossils,  and  by  himself 
of  the  other  fossils,  including  Carboniferous  Brachiopods  and  Fishes, 
and  Triassic  plants  from  Abiquiu,  Hew  Mexico,  and  Sonora,  Mexico, 
the  figures  of  the  plants  occupying  five  of  the  eight  plates. 
During  the  Civil  War,  Dr.  Hewberry  was  a  member  of  the  Sani¬ 
tary  Commission  for  the  five  years  following  September  1861,  and 
had  charge  of  the  work  of  the  Commission  in  the  valley  of  the 
Mississippi. 
In  1866  Dr.  Hewberry  received  the  appointment  of  Professor  of 
Geology  at  the  Columbia  College  School  of  Mines.  In  1869  he  was 
made  State  Geologist  of  Ohio ;  and  the  volumes  published  on 
Geology  and  Palaeontology  contain  much  written  by  him  on  the 
stratigraphy  of  the  various  parts  of  the  State,  but  still  more  on  the 
wonderful  collections  of  Devonian  and  Carboniferous  Fishes  which 
the  rocks  afforded  him,  and  on  numerous  fossil  plants. 
In  1888  Dr.  Hewberry  published,  in  connexion  with  the  United 
States  Geological  Survey,  a  quarto  volume  of  95  pages  and  26 
plates  on  the  Fossil  Fishes  and  Fossil  Plants  of  the  Triassic  rocks 
of  Hew  Jersey  and  the  Connecticut  Valley ;  and  in  1889  a  similar 
volume  of  228  pages  and  53  plates  on  the  Palaeozoic  Fishes  of 
Horth  America.  A  report  of  like  completeness  on  the  Amboy 
Clays  (Cretaceous)  of  Hew  Jersey  was  nearly  ready  for  publication 
two  years  ago,  when  a  stroke  of  paralysis  put  an  end  to  his  long 
and  most  fruitful  scientific  labours.  Besides  his  larger  reports 
above  mentioned,  he  published  many  shorter  papers  connected  with 
all  departments  of  Geology. 
Dr.  Hewberry  was  one  of  the  corporate  members  of  the  U.S. 
Hational  Academy  of  Sciences.  He  was  elected  a  Foreign  Member
