Abstract

In examining for ammonia a soil-extract, prepared by digesting soil for three days in dilute HCl, the author noticed that Schloesing's method (distilling the extract with excess of MgO) gave a continuous separation of ammonia, amounting in this case to.0024 per cent. Another portion of the extract was filtered after the addition of MgO and before boiling. In it the separation of ammonia ceased after boiling a comparatively short time, and the total separated was.0017 per cent. The evident inference is that "part of the amides in Schloesing's extract can be precipitated by magnesia; and, by the second method ‘results are obtained which are much nearer the truth in respect to the ammonia of the soil than by the original Schloesing's method.’”
