This iron, now in the Dresden Mineralogical Museum, was found in 

 1872. It contains iron 93-04, nickel 6-16, phosphorus 0-22 p. c. ; sp. 

 gr. 6*21. Troilite is disseminated through the iron; and some crystals 

 occur which are supposed also to belong to this species. Treatment 

 with acid exposes the granules of troilite, but does not develop Wid- 

 mannstattian figures. Brownish red liquid drops are exuded from the 

 iron, and are referred to the presence of a chlorine-compound. F. W. E.

Eefers to an explanation of this structure given by Daubree, from 

 which the author differs ; the structure is very similar to that exhibited 

 by the surfaces of fragments of gunpowder projected unconsumed from 

 the 35-ton and 80-tou guns at Woolwich. He regards it as due to the
