pui-ple solution, out of which dark brownish-red needles of a 

 potash salt are speedily deposited, as they are insoluble in the 

 alkaline liquid. This potash salt readily dissolves in water, but 

 it is nearly insoluble in alcohol. Its crystals, after being washed 

 with alcohol, were dried in vacuo over sulphuric acid, and sub- 

 jected to analysis. 



0*325 grm. gave 0-143 grm. of sulphate of potash. 



0*2575 grm. gave 0*2475 grm. of bromide of silver. 



According to these determinations, therefore, this salt contains 

 (like the corresponding chloranilate of potash analysed by Erd- 

 mann) 2 equivs. of water, as is shown by the following results : —

The aqueous solution of bromanilate of potash very closely 

 resembles, in its reactions on metallic solutions, those of the 

 chloranilate of potash. It forms with solutions of the greater 

 number of the heavy metals and with that of baryta, difficultly 

 soluble precipitates, whose colours very much resemble those 

 produced by the chloranilate of potash. If sulphuric or hydro- 

 chloric acids are added to an aqueous solution of bromanilate of 

 potash, or to a solution of bromanil in hoi potash lye, the purple 

 colour of the solution immediately disappears, and bromanilic 

 acid is gradually deposited in beautiful, shining, crystalline 

 scales of a reddish colour, which when dried are of a bronze 

 colour. 



/li^Sromanilic acid is not precipitated by acetic acid. 



' '0*2735 grm. of the crystals, when ignited with caustic lime, 

 gave 0*3465 grm. of bromide of silver.

The solutions of bromanilic acid in alcohol and water are of a 

 deep purple colour. Its solution in aether is yellowish, but
