In analyzing the latter substance, it was mixed with carbon 
obtained by exposing crystallized sugar to a high temperature 
in a close vessel. 
Among the advantages this process of analysis presents may 
be enumerated the following: 
I. The saving of material and time; a single combustion suf- 
ficing where two have formerly been found necessary. ere 
properly conducted two complete analyses can be performed in 
a 
ay. 
id Its general applicability, which as would appear from the 
substance analyzed to have the very widest range and to include 
the most diversified combinations of nitrogen with other elements. 
€ complete oxydation, even of those substances pre- 
senting the greatest difficulty in this respect, is perfectly secured, 
as the combustion is completed in a stream of oxygen gas. 
_1V. As an additional recommendation may be considered the 
oo that where a loss of carbonic acid has occurred 
acid present. I have in several instances had an opportunity of
