The addition of uranyl nitrate to an ammonium chloride solution 
of myosin produces a heavy gelatinous precipitate of a uranyl-myosin 
compound, which in solubility resembles the other myosin prep- 
arations. Washed free from excess of uranyl nitrate and from 
ammonium chloride and then dried at 110° C., the various prepara- 
tions yielded on analysis the following’ results, the uranium being 
determined by simple ignition and weighing as uranoso-uranic oxide:
