The form of the mineral, as has already been stated in this Journal ([2], 
xxvi, 354), is that of hornblende; if the alumina is considered as replac- 
ing silica, the oxygen ratio of these to the bases is 2-98 to 1, differing 
very materially from all of t e aluminous ae oe and pyroxenes 
investiga ated by Rammelsberg, iste requiring a portion of alumina to be 
ic in order to be included under the general Seieals (R°R)Si?. —

physicist Kupffer. It has the form of actinolite, and is remarkable from
