T h e result was rather disappointing. T h e alcoholic solutiolis remained clear for many hours. From the aqueous solutions crystals of both bromide and iodide were obtained. hut oi such small size that it was difficult to make out their forms. Those of t h c iodide were sliglitl!. larger :tiid less deliquescelit and under the niicroscope showed rhombic needles aiiti prisiii9, somewhat rounded. so as to rekeiiible soim forms o! uric acid. But the!. \\.ere so difficult to separate from the solutioii without adhering liquid. that lveighiiig coulcl only 1)e approximate. and most likely would include some liquid as well as the tlrj’ substance.
