been required to afford heat, can be used for the production of fat. But 

 whether cold or warm food is to be preferred in a practical point of 

 view, cannot from all this be conclusively deduced. It is a question 

 only to be answered by experience, for the result is entirely dependent 

 on the nature and requirement of the animal. 



4. Meteorite of Arm, (from the Oesterreische Blatt. fur Lit. Kunst, 

 &c, No. 169.) — At a meeting of the " Friends of Science," at Vienna, 

 in 1847, A. Patera presented the results of the chemical analysis of 

 the meteoric iron of Arva, made by him in the laboratory of A. Lowe. 

 The description of the place where it had been found and of the iron 

 itself, had already been published in the Vienna Zeitung of the 17th 

 of April, 1844, and of March, 1845. The fragments of the pure iron 

 employed in the analysis had a specific gravity of 7-814. The iron 

 contained according to the qualitative examination, iron, nickel, a trace 

 of cobalt, and an extremely small quantity of copper. The oxydized 

 surface contained in addition, sulphur, carbon, silica, phosphorus and 

 potassium, probably as unessential ingredients. The results of these 

 analyses were : 



Iron, . . . 8942 9313 9412 



Nickel, . . 8-61 5*94 5-43

A. Lowe has had the kindness to furnish also his own results of two 



quantitative analyses. He found,

At the meeting of the Society the following week, Franz von Hauer 

 presented a series of communications from the Royal Counsellor of 

 Mines, W. Haidinger, the first of which related to the chemical exam- 

 ination of the Meteoric Iron of Arva, communicated by A. Patera. A 

 part of the results obtained was at that time reserved, and as M. 

 Patera had since enjoyed the opportunity of visiting several interesting 

 geological localities of Lower Hungary, he was now prepared to bring 

 forward the portion omitted. Berzelius, it is known, had found in the 

 meteoric iron of Bohurnilitz, a peculiar metallic combination in clear 

 steel-gray folia and grains, composed of iron, nickel and sulphur. 

 Something altogether similar is found in the meteoric iron of Arva. 

 Patera was enabled to collect a sufficient quantity of it to make three 

 analyses, which agreed tolerably well with each other. The folia are 

 flexible and strongly magnetic. Their hardness was 6-5 ; specific 

 gravity 7*01-7-22.
