On the Analysis of the Juvenas Meteoric Stone. 347 
Gicgt of the Juvenas stone was made from the descriptions of 
others, or had resulted from a new examination of the mineral 
f. I may therefore be allowed to state, that it was formed F 
mination of a large specimen of the Juvenas stone, : 
that had been supplied to me by H. Heuland, Esq., out of the 
fine mibteorig cabinet of the late Sir F. Chantrey. Besides, I am 
| f the fact, if any writer has noticed the particular crys- 
I have figured ‘of the anorthite, or made the ee 
respecting the ee of the Juvenas stone which wer 
‘included in the same paper.

composed by carbonate of soda (and by hydrofluoric acid for de- 
termining the soda content). It containe
