 ALPHABETICAL ORDER. 



ACETONE. See Chautard, Gunning, Lieben, Legal, Le 

 Nobel, Malerba, Penzoldt, Reynolds. 



ACETO-ACETIC ACID. See Gerhardt. 



ADAMKIEWICZ'S Keactiou (Proteids). Add the proteid to 

 a mixture of 1 vol. concentrated sulphuric acid and 2 vols. 

 glacial acetic acid. A reddish-violet color is obtained slowly 

 at the ordinary temperature, but more quickly on heating. 

 The liquid has also a feeble fluorescence, and gives an ab- 

 sorption band between the lines b and F in the solar spec- 

 trum.

 Heller, Heijnsius, Hindenlang, Johnson, McWilliam, Mehu, 

 Oliver, Pavy, Reoch, Roberts, Rees, Raabe, Spiegler, Tanret, 

 Zouchlos. 



ALLEN'S Test (Phenol). Add to one to two drops of the 

 liquid to be tested a few drops of hydrochloric acid and then 

 1 drop of nitric acid. Cherry-red color is produced, which 

 is intensified by gentle warming. Alcohol does not interfere 

 with the reaction. On supersaturating with caustic soda the 

 red liquid becomes dark brown,
