PREFACE 



Mr E. S. SALMON, F.R.S., Professor J. W. H. TRAIL, F.R.S., and 

 Professor H. M. WARD, F.R.S. To each and all my indebtedness 

 for their kindness is great, the value of this Glossary being largely 

 due to their ready aid. 



In every volume of similar character to this which I have had 

 to consult, I have found errors, sometimes numerous, occasionally 

 serious. This much larger volume offers a greater chance of error, 

 and it would be vain for me to expect to escape entirely, but I 

 trust that comparatively few errors will be found. 



I am glad that the volume has proved useful both to the student 

 and the expert; to the former as supplying a concise definition, 

 without pretending to supplant the fuller information of the text- 

 book ; to the latter acting as a reminder of some obscure term, or 

 word employed in a special sense.
