PREFACE. 



THIS GLOSSARY is intended to assist the student of scientific 

 yorks, and the general reader, by giving the etymologies and 

 lignifications of such words as are peculiar to the various 

 sciences, together with those of common use having special 

 neanings in science. 



In drawing up the work, the author has collected the defini- 

 ;ions, wherever practicable, from the most modern standard 

 :reatises on the different sciences. He has also availed him- 

 self of the assistance derivable from the " Imperial Diction- 

 iry," and the excellent "Expository Lexicon" of Dr. Mayne. 

 [n all cases he has endeavoured to give the definitions in as 

 joncise and simple a form as is compatible with clearness. 

 Fhe accentuation of the words has been carefully marked ; and, 

 x>r the use of those unacquainted with Greek, the Greek words 

 lave been printed in both Greek and Roman characters.
