PREFACE. 7* 



It only remains to add my regrets that so long a term has 

 elapsed between the death of the gifted and amiable author 

 and the appearance of his work ; this is chiefly due to the fact 

 that it was upwards of a year before the MSS. were placed in 

 my hands, and to the heavy pressure of my own official duties, 

 which has unavoidably retarded its progress through the press.
