" How unfair, and how marvellously incorrect these representations (of 

 Knox's character) are, m?iy be learned from tbe perusal of the work before 

 us ; a work which has afforded us more amusement and more instruction, than 

 any thin.; we ever read upon the subject ; am\ which, independent of its theo 

 logical merits, we do not hesitate to pronounce by far the best piece of history 

 whii h has appeared since the commencement of our critical career. It is ex"- 

 tremely accurate, learned) and concise, and at the same time very full of spirit 

 and animation ; exhibiting, as it appears to us, a rare union of the patient re- 

 search and sober judgment which characterize the more laborious class of 

 historians, with the boldness of thinking, and force of imagination which is 

 sometimes substituted in their place. It affords us very great pleasure to bear 

 this public testimony to the merits of a writer who has been hitherto unknown, 

 we believe, to the literary world, either of this or the neighbouring country ; 

 of whom, or of whose existence at least, though residing in the same city 

 with ourselves, it never was our fortune to have heard till his volume was pnt 

 into our hands; and who in his first emergence from the humble obscurity in 

 which he has pursued and performed the duties of his profession, has presented 

 the world with a work which may put so many of his contemporaries to the 

 blush, for the big promises they have broken, and the vast opportunities they 

 have neglected." EDINBURGH REVIEW, No. XXXIX. 



'* Every page of his book gives full testimony that the writer of it is, by na- 

 turnl constitution, from habit and on principle, a cordial lover of civil and re- 

 ligious liberty. He is a learned man, and an independent thinker " " No 

 Scotsman should ever pronounce the name of Knox without veneration and 

 gratitude. Beyond all question or controversy, be was the greatest benefactor 

 to his native country whom her history records." CHRISTIAN OBSERVER, 

 January 1813.
