INTRODUCTION. Xlll 



name of the recorder may be taken as a sufficient guarantee 

 for the genuineness of the record ; and it would be obviously- 

 unfair to omit all mention of a report because the truth of it 

 could not now be satisfactorily ascertained. Further than 

 this, it has been deemed more prudent to notice erroneous 

 reports for the sake of showing them to be so, than to incur 

 a risk of being supposed to have overlooked them by omitting 

 all allusion to their existence.

 insertion in their proper place, and have therefore unfortu- 

 nately been omitted. To some extent, however, this may
