The tenth number of the excellent series 

 of bulletins issued by the department of 

 geology of the University of California is on 

 Lowsonite, a Neiv-Rock-Forininc/ Mineral from 

 the Tiburon Peninsula, Marion county, Cal. 

 The author, Mr. F. Leslie Ransome, de- 

 scribes the crj'stal form, the optical proper- 

 ties, the chemical composition and the gen- 

 eral physical properties and blow-pipe re- 

 actions of the mineral. It occurs in the 

 form of white crystals projecting from an 

 outcrop of crystalline chist and also in 

 veins traversing the chist.
