Detection of Picric Acid in Urine. 



lOO mils of urine are decomposed by 

 addition of lo mils of a neutral solution 

 of lead acetate. Urobolin, uroerythrin, 

 urochrome, and other biliary coloring 

 matters are precipitated, while picric acid 

 and picraminic acid remain in solution. 

 After filtration the excess of lead is re- 

 moved by treatment with sulphuretted 

 hydrogen, and the liquid again filtered. 

 The yello'w filtrate is shaken with one- 

 fifth of its own volume of ether, and the 

 yellow liquid thus obtained when brought 

 into contactwith woolen fabrics will color 

 these yellow or orange, depending upon 

 the quantity of picric acid present. Upon 

 complete vaporization of the ether an 

 orange-yellow residue is obtained which 

 should be completely soluble in distilled 

 water. 



Color Reaction for Plant Oils. 



P. Sixley and Frehse, in Chem. Rev. 

 11. d. Fett-u. Harzindustrie, 1915, report 

 on a color reaction for plant oils, which 

 the authors claim to be based on the pres- 

 ence of phenol-like bodies. 5 mils of 

 20% solution of sodium acetate together 

 with several drops of solution of deazo- 

 tized paranitro-anilin, are added to 10 

 mils of the oil to be examined. All plant 

 oils, with exception of olive and sun- 

 flower oils show a red or brown-red 

 color. The solution of para-nitro-anilin 

 is prepared as follows: 1.4 grammes of 

 para-nitro-anilin and 2.8 mils of hydro- 

 chloric acid, S/G. 1,180 are mixed with 

 10 mils of hot water, and solution effect- 

 ed. 30 mils of cold water are then added 

 and the mixture cooled to 10° C. 8 mils 

 of 10% sodium nitrite solution are then 

 added, and the whole dilutetl with water 

 to TOO mils.

 thin, haemoglobin, saccharate of iron, 

 protein bodies, nutritive salts, and phos- 

 phates of calcium and potassium. 



Diatrone is a laxative. Each capsule 

 contains the following : phenolphthalein, 

 0.4 gramme, powdered fennel seed, 0.03
