The Travels and Researches of Eminent Missionaries is a well-

tonceived little work, and, as far as it goes, extremely well exe- tented. The idea has probably been taken from the abridgment of the Lettres Edifiantes of the French Jesuits ; and though the ma- terials to work upon are far inferior to the French ones, still Mr. PICKEN has been able to compile a volume of great interest. In one small book, it was difficult, if not impossible, to do more than touch upon the most 'celebrated missions : the author has there- fore preferred a larger scale, and at present to confine his attention to only a part of his plan, waiting the approbation of the public upon his labours, that he may continue then;. In truth, this Volume is almost wholly confined to the South Seas : the Eastern missions, many of which contain incidents of the most Irofound interest, are wholly neglected,-4or example, the labours of,TUDSON, and the admirable narrative of them in'the Burmese empire, are riot even alluded to. We trust the author Will proceed : his subject requires two more volumes similar to the present. He should then proceed to the German and other Protestant missions, which will afford another batch of interesting volumes. He need not be anxious on the subject of encouragement : a good and useful work like this is sure to meet with it. We long for a well-written sketch of the life and character of old SCHWARTZ.
