"^'"peCi'ssor'"'}  Migration  of  Plants  from  Europe  to  America,  105 
Mr.  Sidney  Vines  ^  has  lately  contributed  an  article  to  the  Royal 
Society  which  in  many  respects  confirms  Weyl's  observations. 
An  extract  of  the  seeds  of  blue  lupin  (Lupinus  varius)  in  common 
salt  was  found  to  contain  two  proteids  belonging  to  the  group  of  globu- 
lins and  hitherto  known  to  occur  only  in  animals:  myosin,  a  constitu- 
ent of  dead  muscle,  and  vitellin,  a  constituent  of  the  yolk  of  egg  ;  these 
two  substances,  vegetable  myosin  and  vegetable  vitellin,  were  found  to 
have  exactly  similar  reactions  to  the  animal  substances  of  the  same 
name. 
An  aqueous  extract  of  the  seeds  contained  another  proteid  having  all 
the  properties  of  peptone,  and  agreeing  very  nearly  with  the  a  peptone 
of  Meissner,  or  hemialbumose  of  Kuhne,^  an  easily  decomposable  pep- 
tone formed  by  the  action  of  gastric  juice  on  proteids. — Phar.  four,  and

The  MIGRATION  of  PLANTS  from  EUROPE  to  AMERICA, 
with  an  ATTEMPT  to  EXPLAIN  CERTAIN  PHENOM- 
ENA CONNECTED  THEREWITH.

Paper  read  before  the  Montreal  Horticultural  Society,  1877. 
Underneath  the  great  wave  of  human  emigration  from  the  so-called  Old  to  the 
so-called  New  World,  underneath  the  noisy,  busy  surface  tide  that  has  swept  west- 
ward from  the  shores  of  Europe  to  those  of  America  during  the  last  two  hundred 
years,  there  has  existed  another  and  a  less  conspicuous  wave,  another  and  a  less 
prominent  tide  of  emigration.  Westward  in  its  direction,  like  the  former,  it  has 
silently  accomplished  results  that  seldom  strike  the  superficial  eye,  but  yet  are  scarcely 
less  in  magnitude  than  those  which  have  followed  the  advent  of  the  white  man  to 
the  shores  of  America. 
I  allude  to  that  slow  and  noiseless  immigration  of  European  plants  which  has 
been  going  on  for  many  years,  and  which  probably  commenced  when  the  fiist  Euro- 
pean vessel  touched  our  shores.  Side  by  side  with  the  displacement  of  the  red  man 
by  the  white  man  has  gone  on  the  displacement  of  the  red  man's  vegetable  compan- 
ions by  plants  which  accompanied  the  white  man  from  his  trans- Atlantic  home. 
Not  more  completely  have  the  children  of  the  Pilgrim  Fathers  made  themselves  at 
home  on  the  banks  of  the  Charles  and  the  Neponset,  not  more  completely  have  the 
successors  of  Champlain  and  Jacques  Cartier  established  themselves  along  the  St. 
Lawrence,  not  more  completely  have  the  decendants  of  the  aristocratic  colonists  of 
Maryland  and  Virginia  appropriated  the  shores  of  the  Chesapeake,  than  have  the
