 a view to their utilization in sugar making.

The determination of phosphoric acid by titration, A. Hebebrand (Ztschr. 

 Analyt. Chem., 37 (1898), No. 4, pp. 217-233). — The ammonium-magnesium phosphate 

 obtained in the usual manner is thrown upon a filter and washed with 96 per cent 

 alcohol. The precipitate is then washed into a beaker, dissolved by adding a slight 

 excess of fifth-normal hydrochloric acid, and titrated with fifth-normal sodium 

 hydrate, using for an indicator an alcoholic solution of carminic acid (Acidum carmi- 

 nicum Merck). — l. h. merrill. 



The determination of nitrites, B. Grutzner (Rev. Internal. Falsi/., 11 (1898), No. 



1, p. 21; abs. in Ztschr. Angew. Chem., 1898, No. 13, p. 307).— -From 0.1 to 0.2 gm. nitrite 

 in 500 cc. of water is decomposed with 0.5 gm. potassium chlorate. A known volume 

 (in excess) of tenth-normal silver solution acidified with nitric acid is added and 

 the mixture vigorously shaken. After a few minutes the excess of silver is titrated 

 with tenth-normal sodium chlorid solution.

 110). — This is a brief preliminary note on investigations more fully reported else- 

 where (see p. 128). 



Simplification of Hopkins's method for the estimation of uric acid in urine, 

 O. Folin (Ztschr. Physiol. Chem., 24 (1897), No. 3, pp. 224-245). — The author calls atten- 

 tion to the possibility of error in Hopkins's method, and seeks to correct it by the 

 substitution of ammonium sulphate in place of ammonium chlorid as a reagent for 

 the precipitation of the uric acid. — j. b. lindsey.
