The mineral analyzed by me was found several years since by 
Prof. Root near Oxbow on the road to the Rossie lead mines in 
t. Lawrence county. It occurs in connection with calcite, 
green hornblende (pargasite), and steatite (rensselaerite of Em- 
mons,) while throughout the whole mass of the mineral small 
scales of graphite are disseminate 
here can be no doubt but the wilsonite of Hunt and this 
mineral are identical. 
Wilsonite possesses a composition very similar to gieseckite, 
parophite, dysyntribite and agalmatolite. It is supposed by 
some eminent mineralogists to be an altered scapolite, while 
others consider it to have always possessed its present compo- 
sition, and not to be the result of a metamorphic action.

Art. [X.—On the action of hydrated hypochlorous acid on Oil 
of Turpentine and Camphor; by C. GiLBERT WHEELER. 
Ort of turpentine and camphor are chemically closely related, 
differing in composition by only a single molecule of oxygen
