6 Introduction. 



As to the language and orthography of the book, it is a never- 

 failing fource of intereft, being quite different from any other 

 printed work of the fifteenth century, except the St. Albans' 

 Chronicle from the fame prefs. Among bibliographers it ranks as 

 "rarijfimus" the known copies being fo few that they might pro- 

 bably be counted on the fingers of one hand. 



Looking at the book, then, all round, it will be a convenient 

 plan to confider thefe fubjec"ls feparately, and to treat the volume 

 in its four afpects of Authorihip, Typography and Bibliography, 

 Subject-matter, and Philology.
