 Nora.—On  account  of Ms  instructions  not  having  been  complied  with,  the  Anthor was  obliged  at  the  last  
 rtar.rn.nt  to  remove  the  blocks  of  the  engravings  from  the  hands  of  the  proprietors  of  the  University  Press. 
 Messrs.  D.  Appleton  &  Oo.  kfcdly  allowed  them  to  be  printed  at  their  establishment,  and  the manner  in  
 wMeh  it has been  accomplished, the Anthor  is happy  to think, leaves nothing  to be desired.

 ORNITHOLOGY,  to  the  lover  of  the  beautiful,  to  him  who  delights  in  the  gay  aud  bright  beings  of  nature,  is  one  of  the  most  
 attractive  of  the  various  branches  of  natural  science.  He,  who  passes  through  life  without  a  knowledge  of  the  feathered  creatures  
 constantly  surrounding  his  path  in  the  fields  aud  woods,  rendering  vocal  with  bursts  of  melody  the  groves  and  sombre  places  of  the  
 forest,  pleasing  the  eye  as  they  flit  in  dresses  o f  many  colors  around  the  habitation,  or  teaching  the  much  needed  lesson  of  ceaseless  
 effort  and  patient  care,  as  they  watch  over  and  provide  for,  the  helpless  nestlings,—loses  one  of  the  chief means  by  which  his  own  
 existence  might  be  made  more  cheerful  and  contented,  and  fails  to  understand  one  of  the  most  pleasing  and  attractive  of  all  the  
 creations  of  Omnipotence. 
 That  person  whose  life  is  devoted  to  agricultural  pursuits,  and  by  his  ignorance  of  the  habits  of  his  feathered  friends,  is  led  to .  
 a   blind,  in<u<H>rimin«t.A  slaughter  o f  the  very  beings  whose  instincts  teach  them  to  work  for  his  benefit,—probably  only  learns  the  error  
 he  has  committed,  after  failing  crops  and  barren  fields  prove  to  him  that  the  death  of  his  little  winged  help-mates  has  but  given  new  
 life  and  vigor  to  the  hurtful  grub  and  destructive  insects  which  have  passed  over  the  land,  leaving  but  a  desert  behind. 
 Investigation., of  ornithological  science  has  progressed  rapidly  within  the  last  half  century,  aud  much  light  has  been  thrown  upon  
 many  difficult  and  perplexing  subjects,  encouraging the  worker  to  persevere,  although  so  much  still  uncomprehended  lies  beyond.  One 
 great  evidence  of progress is,  that Ornithologists  are  more  and more  turning  their attention  to  the study of the  anatomy  of their  subjects, 
 and  in  the  bony  structure  and  formation  of  the  soft  parts  find  truths  which  no  investigation  of  the  outside  covering,  however  minute,  
 to  which  so  many  confine  themselves,  can  possibly  reveal. 
 The  want  of  knowledge  in  that  perplexing  problem:  What  constitutes  a   species?  the  seeming  impossibility  to  afford  some  
 explanation  of  this  mystery  which  may  be  acceptable  to  all—the  apparently  hasty  manner  in  many  cases,  in  which  birds  are  described  
 as  distinct  from  all  those  heretofore  known—the  general  shunning  of  varieties,  those  unwelcome  facts  which  are  met  with  when  least  
 expected  or  desired,  bringing  to  naught  some  of  the  most  plausible  theories—all  together  warn  us that  it  is  best  to proceed  with 
 caution  towards  our  conclusions,  lest  our  labors  should  be  but  vanity,  our  castles  only  b u ilt  in   the  air. 
 Of  the  making  of  species,  even  as  was  said , of  books,  by  the  Wise  man  of  old1,  there  is  no  end. 
 Every  naturalist,  although  perhaps  unable  to  give  a  definition Of  what  a  species  is,  which  may  be  acceptable  to  his  fellow-laborers,  
 has  nevertheless  some  idea, of  what may  be  necessary  for  an  animal  to  possess  in  order  to  occupy  such  a  rank,  and  completes  his  own  
 work  guided,  in  the  majority  of  cases,  from  his  individual  view  of  the  matter.  Thus  various  methods  of  treating  a  subject,  and  much  
 confusion*  not  infrequently  arise. 
 *  Genera  and  species  are,  in  many  instances,  arbitrary  terms, .founded  at  times  not  so  much  upon  information  received,  from  which  
 a,  decision  has  been  satisfactorily  reached,  as  upon  a  supposition  that  allowed  an  opinion  to  be  hastily  formed  with o u t  a  sufficient  
 knowledge  of  the  subject  having  been  first  attained,  to  prove  that  the  conclusion  arrived  at was  entirely  correct. 
 A species  may be  defined  as  that  being,  which  has  the power  of reproducing  itself,  of  transmitting  its  prominent peculiarities  regularly 
 to  its  descendants,  and  at  the  same  time  presenting  characters  radically  distinct  front  those  found  elsewhere. 
 And  although  in  the  majority  of  instances  perhaps,  some  such  idea  as  that just  expressed,  has  influenced the  action  of  Ornithologists,  
 yet  however,  specimens  have  been  given  specific  rank,  which  presented  but  the  slightest  variation  from  well-known  forms,  and  this  
 refining  process  has  occasionally  been  carried  to  such  an  extreme,  that  the  merest  difference  of shade  in  color  has been  deemed  sufficient  
 to  constitute  a  species—nay,  a  still  greater  stop  h a s   been  taken,  and  examples  have  been described as  distinct which  so  closely  resembled  
 others,  that,  should  the  labels  which  indicated  them,  be  lost,  the  describer  himself  would  be  unable  to  distinguish  one  from  the  other.  
 Such manner  of  procedure  admits  of  no  dcfisnse. 
 •  varieties  occur  in  every  class  of  created  beings,  and  are  the  result  of  various  causes,  usually  originating  in  the  parent  stock;  and  
 by  seizing  upon  one  of  these,  which  may  exhibit  only  a  trifling  divergence  id  form,  or  color  of  plumage,  from  that  which  has  perhaps  
 been  long  known  and  accepted  as  a  species,  and  elevating  it  to  a  separate  rank,  the  describer at  best  but  anticipates,  as  a   fixed  fact,  
 a  re su lt"w h ic h   the  variety,  under  the  most  favorable  auspices,  would  have  probably  been  a   long  period  in  reaching,  and  which  also  
 might  never  have  progressed  farther  towards  a;  radical  difference than  was  then  p resented;’b u t  might  have, indeed  returned  again  in  its  
 descendants  to  the  similitude  of  th e   stock  from  which  it  sprung. 
 Hybridism  among  birds  in  a  wild  state  is  not  infrequently  the  source  from  which  many  varieties  arise,  and  oftentimes  these  are  
 designated  as  species,  their  origin  not having  either  been detected,  or  at  least  acknowledged.  But  several  causes  intervene  to  prevent  the  
 long  continuance  of  these  forms,  one  of  which  is  the  general  infertility  of  such  individuals;  or, i f   in  any  instance  this  should  not  be  
 tho  case,  then  the  inability  to  keep  themselves  separated  from  the  allied  species  from  which  they  derived  their  existence,  would,  in  a  
 few  generations;  necessarily  return  these  varieties  to  the  likeness  of  one  of  the. sp ile s  to which  they  owed  their being.  Their  individual 
 peculiarities  would  be  swallowed  up  by  one  or  the  other  of  the  dominant  races.
