THE GEOLOGIST. 



out the next morning, his horse was frightened by the sight of a 

 black stone, deeply bedded in the soil of the road, the ground around 

 it being depressed and creviced. When dug out the meteorite 

 weighed abcut 7 lbs. The finder broke off some fragments, and the 

 remainder, weighing 5^ lbs., was deposited in the Museum of the 

 Reformed College at Debreczin. This meteorite has the shape and 

 size of a small loaf of bread. Its crust is black, covered with con- 

 centrically radiate furrows and tubercles. Its mass is greyish-black, 

 with globular concretions, and acts energetically on the magnetic 

 needle. Its internal structure, in general features different from that 

 of any meteorite hitherto known, most resembles in its structure 

 that which fell at Eenazzo. 



The Kaba meteorite has been found to contain a certain quantity 

 of carbon, together with another substance into the composition of 

 which carbon entei-s. Professor Wohler, of Gottingen, found the 

 composition of this substance to bear a great analogy with certain 

 minerals of a wax-like constitution, such as ozokerite, scheererite, &c,, 

 which are all carburets of hydrogen.

AND M. HaIDINGER. 



The fall of this meteoric stone, on May 19th, 1858, at 8 a.m., was 

 attended with the usual phenomena : a small black cloud in the air, 

 a hissing and thunder-like noise, heard at two Austrian (five English) 

 miles distance, a short and loud explosion at the moment when the 

 stone — in a state of considerable heat — touched the ground, into 

 which it penetrated to a depth of three inches. Lieutenant-General 

 Count Coronini, Governor of the Banat, sent the stone to the Imperial 

 Geological Institute, and it is now added to the rich collection of 

 meteorites in the Imperial Museum of Mineralogy. 



The meteorite of Kakowa (although complete as in the moment of its 

 fall) bears the appearance of being a fragment from a larger mass, with 

 markedly rounded angles and edges, and a black cortical substance, 

 about half an inch thick, extending into the interior in the shape of a 

 vein. Minute particles of metallic iron are nearly uniformly spread 

 throughout the whole stone. 



Professor W^ohler submitted it to an analysis. The portions extracted 

 by the magnet give: metallic iron, 82.95; nickel, 11.41; cobalt, 

 1.08 ; and inappreciable quantities of phosphorus, copper, and oxide 

 of chrome. 



The analysis by means of carbonates of potash and soda gave : 

 sihca, 41. U ; magnesia, 27.06 ; oxidulated iron, 27.47 ; lime, 0.68 ; 

 and some oxidulated manganese. 



Fluoric acid decomposed the substance of the meteorite into : 

 silica, 41.96; magnesia, 27.06; oxidulated iron, 23.95: alumina,
