REVEREND AND DEAR SIR,--In pursuance of the promise given in my epistle of last week, which I trust in the Lord you have received, I again address you. In the first place I must intreat you to peruse and to read to the Committee the enclosed Latin certificate penned by Mr. Lipoftsoff, a gentleman as little inclined to be prodigal of praise, as was of old the learned Scaliger himself, to whom in many points indeed, he bears no faint resemblance. In the second place, I must inform you that a few hurried lines are all that I can afford to write at present; my proof sheets are rushing in so fast that time is exceedingly precious to me, and I grudge every moment that is not devoted to my Maker or to my great undertaking. Before this letter reaches you St. Mark's Gospel will have passed through the press. The two remaining Gospels will be printed before the arrival of Christmas, and by the first of May the entire New Testament, in the Mandchou language, will have been published. I wish this intelligence to be communicated to the public, who are at liberty, provided the Lord does not visit me with some heavy affliction, to hold me culpable, if my assertion is belied by the event. It is true that were I to pursue the common practice of editors, it would be impossible to complete the work in less than two years; the quantity of proofs, successively required for every sheet, fail not, in general, to retard the progress of all such undertakings. My beloved friend Mr. Swan published in this city a small tract in Mongolian; he found that it was absolutely necessary to demand six proofs of every sheet, for in the second, nay the third proof, there were frequently as many errors as in the first, from the compositors not being able properly to read the corrections. But I never entrust the task of making alterations in the press to other hands than my own. Having corrected the first proof at home, I proceed to the printing office and rectify all errors myself. I consequently never require more than two proofs; the second, which I generally show to Mr. Lipoftsoff, is frequently faultless. I am so perfectly convinced of the excellence of this plan, that it is my firm intention to pursue it in whatever foreign, or even English works, it may be my destiny to edit.
