OBSERVATIONS. 2 j 
In the Eldmens de Min'eralogie of Mr„ 
Sage this Wood-tin is mentioned under 
the name of Mine d'etain en jlaladlite. 
Mr. Rome de Rifle defcribes it according 
to Mr. Brunnich j and in his Mineralo- 
• ^ o 
gical Tables* which he has annexed to 
his treatife of the external charadteriftic 
figns of minerals, he adds to the deno- 
mination of Mr. Sage hematite d’etain-. 
Mr. Bergmann alfo fpeaks of this mineral 
in his Dofimafia via humida, in the fol- 
lowing words: Nuper variationem in 
Anglia inventam obtinuimus peculiarem, 
quae ftratis fphaericis contiguis, radiifque 
e centro prodeuntibus, haematiten fufcum 
onanino refert. 
The following defcription, which was 
communicated to me in writing by In- 
fpcdtor Werner of Freyberg, our mafler 
in minerography, cannot fail to be parti¬ 
cularly agreeable to mineralogifts*
