The determination of citrate-soluble phosphoric acid in 

 Thomas slag, O. Bottcher (Chem. Ztg., ;> (1897), No. 7s, pp. 783, 

 784). — In a previous article 1 tlie author discussed Wagner's citrate 

 method and proposed a modification. As a result of further study he 

 proposes the following: The phosphoric acid is brought into solution 

 according to Wagner, 5 gin. of the slag (without trituration and sifting) 

 being brought into a half liter flask and the latter filled to the mark 

 with Wagner's dilute ammonium citrate solution at a temperature of 

 17.5° C. The flask is closed with a rubber stopper and kept for 30 

 minutes in a rotary machine making 30 to 40 revolutions per minute. 

 The solution is filtered at once, the entire liquid being brought into a 

 large filter, or it is poured off into another vessel and then filtered. As 

 soon as possible, at least within a day, 50 cc. of this clear filtrate is 

 treated with 50 cc. of Maercker's citrate solution and 25 cc. of Maercker's 

 magnesia mixture, the whole agitated for 30 minutes in a shaking 

 apparatus, and as soon as possible filtered through a Gooch crucible, 

 dried, ignited 3 or 4 minutes in a Bossier furnace, cooled in a desiccator 

 and weighed. — J. t. Anderson.
