1. On the EocKS 0/ Native IrojSt discovered in 1870 in Greenland. 



By M. DATJBRiE. 

 [Comptes Eendus de I'Acadeinie des Sciences, Tomes Ixxiv. & Ixxv.] 

 M. Dafbr^e has received from M. Nordenskiold some specimens of 

 native iron discovered by the latter at Ovifak, in Greenland (see 

 pp. 1 and 44 of the present volume of the Quarterly Journal). In 

 these papers he gives the results of his examination of them. They 

 were regarded as of extraterrestrial origin by their discoverer and 

 other Swedish chemists ; and this view has been supported by M. 

 Wohler (Nachr. Kon. Gesellsch. Gottiugen, 11th May, 1872), whilst 

 the opinion has been expressed by some geologists in this country 

 (Quart. Journ. Geol. Soc. loc. cit.) and in France (Bull. Soc. Geol. Fr. 

 xxix. p. 175) that they might be of eruptive origin. 



The four specimens examined by M. Daubree were taken from the 

 basaltic rock. The fragment first specially referred to is a blackish 

 metallic mass, which, when polished, shows imbedded in the mass a 

 network of white lamellaB (like schreibersite) and irregularly scattered 

 brassy grains (troilite). The author describes the method of analysis 

 employed in the examination of this mass, and gives the following 

 as its results, which differ in some respects from those given at 

 p. 45 : —

In a second paper M. Daubree distinguishes three types among 

 the so-called meteorites of which he has received specimens, namely :
