The muchused macro Kjeldald battery of digestion flasks and distilling flasks requires atleast two hours to complete a series of twelve determinations in addition to re-quiring large amounts of acid and caustic soda. Thus, the apparatus describedlater effects a great saving in time as well as in chemicals. So far as accurac}is concerned, by using Folins technic for urine- highly satisfactory recoveries ofadded nitrogen have been obtained by the author, as accurate as the macroKjeldahl method if not more so. *From the Laboratory Department, Henry Ford Hospital, Detroit, Mich. 53 54 THE JOURXAL OF LABORATORY AND CLINICAL MEDICINE The apparatus which is illustrated in the accompanying photograph consistsof the base plate, , into which 12 micro burn
