ANALYSIS OF SOME FOSSILS. $S3' 



of this by the name of bronzed metaUoid larnello-fibrons

 Labrador hornblende, of which he makes a distinct species

la my opinion our bronzite cannot be ranked with the^iffer^^"*: ffom 

 emerald, or the diallage, as it is of a different nature; for, 

 according to the analysis of Mr. Vauquelin, the diallage 

 not only contains a little magnesia and alumine, but a 

 preponderant proportion of lime, to say nothing of 

 the chrome. it is distinguished too by melting alone 

 into a scoria before the blowpipe, while the bronzite is in- 

 fusible.

Extract from a Letter of Mr. Gehlen, on the Anali/sis of 

 the Kannelstein and Greenland Garnet , on some Metallic 

 Succinates J Sfc* 



IN my way through Berlin Mr. Klaproth gave me the ana- Analysis of 

 Jyses of the kannelstein, Greenland garnet (almandine),^°^^^°^^^^ 

 and haarkies (capillary pyrites, Brochant, II, 127). The 

 first, you know, has been classed in the zirconian genus; 

 and Mr. Lampadius, of Freyberg, imagined he found in it 

 zircon and potash. Mr. Gruner, of Hanover, and Mr. 

 Trommsdorf, of Erfnrt, who have analysed the Greenland 

 garnet, assert, that they found zircon in this also. Neither 

 of these fossils however afforded Mr. Klaproth any of this 

 earth, the following being the results of his analyses. 



The kannelstein yielded - silex - - 38*80 Kannelstein., 

 lime . - 31-25 



alumine - - 21 '20 

 oxide of iron 6*50
