An interesting novelty is embodied In
n new safety lamp proposed by q Frei-
berg mining student. The action of
the lamp Is based on the property Of

chamber are placed pieces Of pumice
stone impregnated with platinum black;
and as all the air for maintaining the
combustion passes through this cham
Der, all fire damp Is destroyed before
reaching the open flames.
