Alfred Newton, M.A., F.R.S.> etc* 
Several causes induce us to hope that the present Record^ 
may he found more complete than any of tliose which have pre- 
ceded it ; and though, as before, wc stand greatly indebted to 
the good offices of many kind friends, wc believe we have omitted 
few works which could justly claim a place*. There seems 
to us no need to particularize any of the publications herein 
mentioned; and if, in the following pages, some are distin- 
guished typographically, this is done on the responsibility of the 
Editor. The ornithology of the Paljearctic Region engrosses, 
as it most likely long will engross, the greatest share of atten- 
tion; but it is extremely gratifying to find that constantly in- 
creasing interest is taken in that of remoter regions. We 
think, also, that there is manifest a growing desire on the part 
of ornithologists to become acquainted with eaeh other^s work 
before committing themselves to print ; for it is certain that the 
flagrant cases of wilful neglect which some years ago w^ere far 
from uncommon are now comparatively rare, if indeed they 
have any existence. We accordingly deem the present state of 
our science to be healthy; and with fresh labourers springing up 
on every side, while the elders (as in Mr. G. R. Gray^s case) 
display their wonted activity, its most zealous eultivator need 
have few fears for the future.

It has hitherto been so great a pleasure for us to speak in the 
highest terms of the Reports executed by Dr. Hartlaub that it 
is with as much pain that we must notice some indications of 
* The concluding ITeft of the ‘ Journal fiir Ornithologie ’ for 1869 did not 
appear until after the first for 1870 ; and we have not been able to see a com- 
plete set of the ‘ Proceedings ’ of the Philadelphia Academy.
