Peculiarities lately found in Iron-font* 3 1 



al&ly fimilar : externally they were covered with a hard black 

 coat or incruftation, which in fome parts had the appear- 

 ance of varniih, or bitumen ; and on moft of them were frac- 

 tures, which, from their being covered with a matter fimilar 

 to that of the coat, fcemed to have been made in the fall, by 

 the ftones ftriking again ft each other, and to have parTed 

 through fome medium, probably w intenfe heat, previous 

 to their reaching the earth. Internally, they confided of a 

 number of final 1 fpherical bodies, of a if ate colour, embedded 

 in a whitifh gritty fubftance, interfperfed with bright mining 

 fpieula?, of a metallic or pyritical nature. The fpherical 

 bodies were much harder than the reft of the (lone: the 

 white gritty part readily crumbled, on being rubbed with a 

 hard body; and, on being broken, a quantity of it attached 

 itfelf to the magnet, but more particularly the outfkle coat or 

 Cruft, which appeared almoft wholly attradtable by it. 



As two of the more perfect ftones which I had obtained, 

 as well as parts of fome others, have been examined by fe- 

 veral gentlemen well verfed in mineralogy and chemiftry, I 

 (hall not attempt any further defcription of their conftituent 

 parts; nor ihall I ofter any conjecture refpedting the forma- 

 tion of fuch Angular productions, or even record thofe which 

 I have heard of others, but leave the world to draw their 

 own inferences from the facts above related. I ihall only 

 obfervc, that it is well known there are no volcanos on the 

 continent of India ; and, as far as I can learn, no ftones 

 have been met with in the earth, in that part of the worlds 

 which bear the fmalleft refemblance to thofe above defcribed,

 lately found in Lron-Jlone from Huchenburg and Ifchenburg* 

 By Mr, Cramer, Cowifcllor of Mines at Altenkirchen* m 



JL H E firft mineral I fhall here mention is native iron. 

 It is well known that a difpute has long exifted among mi- 

 neralogifts rejecting the actual exiftence of this fubftance; 

 that by fome it has always been doubted ; and that, befkles 

 the monftrous mafs of which profeflbr Pallas has given a cir- 

 cumUantial defcription, few fpecimens have ever been pro- 

 duced to give fupport to the afiertion, that this mineral is 

 found in a natural ftate. The certainty of its exiftence has
