And the Neighboring Islands Alderney, Sark, Jethou, Herm; Being a Small Contribution to the Ornithology of the Channel Islands

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility.
