xii INTRODUCTION. 



book of travels three times over, in order to obtain these 

 materials; but chiefly through the illnesses before referred 

 to, of Professor Sedgwick. Surely real interest in matters 

 so absorbing and vitally important in most respects, 

 cannot have in the mean time waned. This delay has 

 been very beneficial, since I have hereby gained some 

 valuable contributions to the work, of various kinds. It 

 is obvious, on comparing the excellency of the type, &c. 

 in this book, with its small price, that a large circula- 

 tion alone will help forward the two libraries. This 

 smallness of price is intended to meet the wants and 

 means of the many. 



For my own part, whatever trouble or anxiety may 

 have fallen to my lot, in connection with these deeply 

 interesting matters, will be amply repaid by any small 

 amount of good thereby produced. This matter I pray- 

 erfully leave in the hands of our gracious Lord, who 

 doeth, giveth, and receiveth that which seemeth him best; 

 resting content with that command generally given, " in 



THE MORNING SOW THY SEED, AND IN THE EVENING 

 WITHHOLD NOT THINE HAND; FOR THOU KNOWEST NOT 

 WHICH SHALL PROSPER, WHETHER THIS OR THAT."
