VIII PREFACE. 



to present formidable obstacles against the success of a foreigner in 

 every literary attempt. I have therefore submitted my manuscript to 

 the revision of a gentleman who has taken a warm interest in assisting 

 the prosecution of my inquiries. He has, however, in every instance, 

 advised me to retain my own expressions unaltered, as conveying with 

 the greatest fidelity and precision the ideas of my own mind, unless 

 where, from the very different genius of the German language, they 

 would have presented a meaning obscure, or liable to be mistaken by 

 the English reader. These observations will at once account for, and 

 it is trusted also plead for an indulgent allowance in behalf of, that 

 occasional harshness of construction and style, which it is felt must 

 still adhere to a work composed under such circumstances. 



I have finally to acknowledge rny obligations to the Very Rev. the 

 Dean of BRISTOL; RICHARD BRIGHT, Esq. of Ham-Green ; the 

 Rev. W. D. CONYBEARE, of Brislington ; the Rev. Professor W. 

 BUCKLAND, of Oxford ; the Rev. Professor A. SEDGEWICK, of Cam- 

 bridge ; the Rev. R. HALIFAX, of Standish ; the Rev. Dr. COOK, of 

 Tortworth ; C. STOKES, Esq. of London ; JOHN HAWKER, Esq. of 

 Dudbridge ; and to all the Gentlemen in Bristol and its neighbourhood 

 possessing collections of organic remains, the richest perhaps in this 

 department which England contains, for their liberality in furnishing 

 me with specimens, and in giving every aid to my inquiries which a 

 free access to their cabinets and the assistance of their valuable 

 information could afford.
