WOBURN ABBEY. 
Ir is not every one who has the taste, capacity, or 
leisure for the scientific study of Natural History. But 
there are few persons who do not feel that some know- 
ledge of the processes and products of Nature increases 
the enjoyment of country life. To supply this knowledge 
in a form at once easily assimilated and _ scientifically 
accurate is the object of the Wosurn SERIES OF 
Natura. History. 
Each subject will be treated by a writer who has 
made it his special study. In this volume, therefore, 
as in all the succeeding volumes, the writer speaks for 
himself, and the Editor has not attempted to impose 
his own opinions on those who have been asked to 
contribute to the series.
