APPENDIX B. 
DATES OF ORNITHOLOGICAL WORKS. 
The following compilation is tlie first attempt to provide a means for 
the determination of the exact dates of piibhcation of works deafing with 
Ornithology. 
I here give those ascertained in connection with the works cited 
in my “ List of the Birds of Australia/’ or the place of appearance of 
such data as a means of reference. 
My friends, C. Davies Sherborn and C. W. Richmond, are the only 
two who need special recognition, as these workers have collated many 
difiicult works, and any collations I have made have been developed 
through their initiative. Both have also much more material than I possess, 
but it is not easily available. 
The present list is incomplete and imperfect, but will serve as a 
basis and will show what I have brought together. If similar lists were 
pubhshed in connection ' with American and European birds, the bulk 
of ornithological works would be brought under survey. 
This seems a necessary preliminary to the preparation of accurate 
Lists, but the problem has never yet been skiKully handled. A few 
European works are here mentioned, but no attempt has been made to 
deal with them in detail. Little care has been taken even by the most 
accurate workers, as I find a well-known worker often citing inaccurate 
dates without any investigation whatever. I therefore look to one of 
the younger generation for the compilation of a similar list to the one 
here presented. ^ 
Many of the items that follow are famifiar to a few workers, but 
some entirely novel are included, and it is put forward as a base only. 
Annaes Magazine Natural History. At the present time 
pubhshed monthly on the first of each month, and six months constitute 
a volume, twenty volumes {i.e. ten years) forming a series. It is necessary 
to remember that at the beginning there were two opposition magazines, 
of which this is the survivor.
