 are discussed, with the general (onclusidu that the latter only is in all cases reliable. 



Comparison of Kjeldahl-Wilfarth and Stock methods for determining nitro- 

 gen, E. Cavazzaxi and A. t'Kctoxi (Aun. Chim. e FarmakoL, 20 (1894), p. 87; aba. 

 in Anah/sl, 19 (1894), Oct., p. '2U). — Comparative analyses by the authors of blood, 

 milk, and nrino showed that Stock's method (E.S. R..4, p. 86) was considerably 

 more rapid than the Kjeldahl, but gave lower results. The difference was least 

 with milk, amounting with blood and urine to 8 to 9 per cent. They conclude that 

 Stock's method is only applicable where rapidity is more important than extreme 

 accnracy.
