of Meteoric Iron 'which has yet been discovered in Europe. 411 



Laugier's latest Analyses of Meteorites from Polayid. Com- 

 municated by Dr. N(EGGERATH. 

 The preceding account had ah-eady been sent to press, when 

 I received the last number (6^ Ann, 2^ Cah.) of Memoires du 

 Museum d'Histoire Naturelle, in which Laugier inserts the ana- 

 lysis of a meteoric mass of iron similar to that of Pallas. It also 

 contained sulphur. Laugier examined two varieties of this me- 

 teoric iron found in 1809 at Brahin, in the district of Rziezyca- 

 Minsk. He saj^s, that it perfectly resembles that of Siberia, 

 being in like manner full of cavities, which seem to be covered 

 with a vitreous greenish-yellow substance, which was easily 

 detached, and was considered to be olivine. 



The variety of this iron, which he calls the blueish, was 

 found on analysis to contain 



Pure iron 87"35 



Silica 6-30 



Nickel 2-50 



Magnesia 2-10 



Sulphur 1-85 



Chrome 0-50 



100-60 

 The white variety contained 



Pure iron 91*50 



Silica, somewhat tinged by iron 3*00 



Nickel 1-50 



Magnesia 2*00 



Sulphur 1-00 



99-00 

 Laugier also analysed the following meteoric stones from 

 Poland :— 



1. One which fell on the 30th of June 1820 at Lixna, near 

 Dunabourg. Its outward appearance was like that of most 

 aerolites, and it contained, as many of them do, small shining 

 globules, which could not be pulverized, and on being sepa- 

 rated by a magnetic bar, composed a full fourth of the whole 

 mass. 100 parts of this aerolite with its shining globules con- 

 tained, — Oxide of iron 40*00 



Silica 34-00 



Magnesia 17*00 



Sulphur 6-80 



Alumina l'^^ 



Nickel 1-50 



Chrome 1-00 



Lime 0-50 



Traces of copper and manganese
