As my object was to procure a paces Roe of — a re-exam- 
ination of the above minerals was not ecessary. One 
hundred pounds of fragments of beryl were coe from Ac- 
- worth, New Hampshire, and ground in a gold-quartz mill, and 
pshire, gr da 
osed according to the following me 
Methods for the decomposition of beryl. 
1. By passing chlorine gas over a calcined mixture of lamp-black, oil, 
beryl. 
gu: 2, By treating beryl with concentrated hydrofluoric acid and sulphu- 
acid. 
3. By digesting seven parts of beryl and thirteen parts of fluor spar 
in b Meakicar arts of concentrated sulpburic acid. 
4, By fasting beryl with three parts of fluorid of potassium, and digest- 
ing in pelone acid. OPES ee 
5. Tusing beryl with flu ammonium, and digesting in sul- 
phuric ee
