Analysis of the Braunau Meteorite. 171 



APPENDIX. 



As my communication of November 30th was too late for the 

 last number, I am now enabled to add a further note, derived from 

 u The Botany of Capt. Beechey's Voyage, 71 to which I have 

 only just procured access. A Californian plant, considered by 

 the authors as a probable variety of Chenopodium anthelmintic 



cum 



ing observation appended to the description. — " The genus Rou- 

 bieva of Moquin-Tandon, distinguished from Chenopodium by 

 its vertical seed, and from Agathophytum by the keeled segments 

 of its perianth, which form a pentagonal covering to the nut, 

 was constituted for one or two South American species, but 

 ought to include the present plant and a few others indicated 

 by Spach under his Ambrina, which does not differ." — Suppt 

 Bot, Beechey's Voy., 1841. 



It would hence appear that my view of the identity of the gen- 

 era Roubieva and Ambrina (the latter as constituted by Spach) 

 has been anticipated by Hooker and Arnott, but, from their con- 

 trasting characters, as given above, these distinguished botanists 

 did not seem to contemplate the admission of the species with hori- 

 zontal seeds, constituting the genus Botrydium of Spach, but 

 which is reduced by Moq.-Tand. to a section (Botryois) of the 

 genus Ambrina. J. C.

Art. XIII. — Analysis of the Braunau Meteoric Iron; by Dr. 



N. W. Fischer.* 



(Continued from vol. v, p. 342.) 



In the enquiry instituted by Prof. Duflos and myself, we made use 

 °f the filings which, as has been mentioned, I had been permitted 

 to remove from the mass during my presence at Braunau, and we 

 could thus only treat of the iron as a homogeneous body. Now 

 however having, by the especial kindness of Dr. Rotter, been put 

 into possession of a solid mass of more than 20 grammes in 

 Weight, my attention was primarily directed to ascertain of what 

 heterogeneous substances this meteoric iion consists ; and the re- 

 sults at which I have arrived are, that it contains three such bodies. 



One of these is by far the most predominant, forming: the gen- 

 ial mass, and is a compound of iron, nickel and cobalt, with 

 traces of other substances, as stated in the result to which our 

 investigations led us.f

t Several of the substances alluded" to there, are probably attributable to the 

 presence of the two other bodies
