96 THE ANALYST. CORRESPONDENCE. COUNTY ANALYST’S OFFICE, DARLINGTON, March loth, 1893. THE STOCK NITROGEN PROCESS. To the Editors of THE ANALYST, This method, if one may judge from the character of the discussion which followed the reading of my last communication upon the subject, appears to have reached a stage at which, and beyond which, no further information is to be elicited by either argument or assertion. If it needs anything mo~e to establish its claim to a front rank among accurate methods for the determination of nitrogen in organic bodies, it needs work. May I say to analysts who intend to try this new process, that the confession of a skilled and experienced operator (Mr. Allen) that he “ found it desirable,” in working the Kjeldahl process as now known, “ to make two or three determinations and take the highest result,” is in singular contrast with the fact that this same method has been selected as a standard of accuracy by those who have had most to say in criticising my process. And may I also say that I shall be most willing to do all I can, if applied to by letter, to help others over difficulties I have myself surmounted. Yours obediently, SIRS, W. F. KEATING STOCK.
