a gentle heat. 
The water in the receiver gave indications of chlorine. 
The residue’ in the matrass was submitted repeatedly to the 
lack precipitate caused thereby was put ona filter and the liquor 
Passing through was again acidulated with nitric acid. It was 
how concentrated by evaporation, and in the first place caustic am- 
monia, and subsequently oxalate of ammonia, were added thereto. 
A white cloudiness was produced thereby, which did not dis- 
appear upon the addition of acetic acid, indicating, therefore, lime 
and consequently calcium. 
The fluid filtered from the oxalate of lime had phosphate of 
ammonia added to it. 
_ After a considerable interval a crystalline precipitate was formed, 
Indicating the presence of magnesia, and consequently magne- 
sium. The portion of the nitric solution evaporated to dryness, 
Which was insoluble in ammonia (oxyd of iron), was treated with 
hydrochloric acid, which dissolved it entirely with the exception 
a few white flaky particles. a
