EXTRACTS FROM REVIEWS. 



'The authors of this catalogue may take a pride in their work, which has evidently been 

 executed with most conscientious care. They have given a short introductory exposition of the 

 principles by which they have been guided, and an excellent brief sketch of the physical aspects 

 of Yorkshire, and the summary of the results of their investigation of its Vertebrata. The little 

 book is a most v.iluable contribution to British zoological literature.' — Auti. is' Mag. Nat. Hist.
