 Co. London: Triibner and Co. 1890.) 



This, the concluding volume of the series of Mr. Bancroft's gigantic work,

 been our privilege to read during the last twelve or thirteen years none have 

 afforded us more real pleasure, and it is with feelings of no little regret that we 

 are compelled to look on this as the last of the series. One of his reviewers 

 has well said, " Your work will remain to coming ages a treasure-house of 

 information."

 less understood. This is doubtless due in a great measure to the scarcity of 

 literature on the subject. The book before us comes, therefore, very oppor- 

 tunely. It commences with a short account of the more important character-
