ZENBERGER has succeeded—according to his own statement—in preparing 
acetates of cloring, iodine and other electro-negative radicals. When 
acetate of soda is mixed with chlorid of iodine the ensuing reaction is 
represented by the equation

The new substance C, Hy O,I is solid, abies and crystalline ; it is iso-
