x PREFACE. 
I must not close without offering my thanks to Mr. 
Justen (Dulau & Co.) for his cordial co-operation and 
valued assistance in advice, &c., during the passing of the 
work through the press. 
In the words of Dr. Jonathan Couch, ‘the father of 
Cornish Zoology,’ I will conclude. ‘The study of synonyms 
is at all times a far more difficult and tedious task than 
the study of the things themselves ; but, tedious as it is, 
it is necessary to be undergone by all who desire to know 
what has already been said on the subject.’
