iv PREFACE 



It need hardly be explained that Mr. Oldfield Thomas, 

 F.R.S., has influenced the preparation of this Catalogue in 

 many ways, and specially by the continued efforts he has 

 made, for a number of years, to encourage the growth of the 

 Collection under his charge, as well as by his numerous 

 contributions to the literature of the subject.
