PREFACE vii 



remains of Varro's villa and aviary at Cassino, and 

 for his valuable explanations of many topographical 

 difficulties; to the University Library of Aberdeen 

 for allowing me the use of books which I could 

 with difficulty or not at all procure elsewhere ; and, 

 finally, to Messrs. G. Bell and Sons for everything 

 for which a generous and public-spirited publisher 

 may be thanked.
