In . paper read before the Chemical socict,
London. the announcement is made that, pur
suing the researches which led some time AGO
tothe remarkable discovery that nicke formed
with carbon monoxide the volatile compound
N 70 OI4, investigation hus now resulted in
obtaining o similar body containing iron
though its preparation Is difficult and ths
