Allanite. Vol. I. 



East Greenland to Scotland by Mr. C. Giesecke; it has 

 since been reported from one locality in Norway, two 

 localities in Pennsylvania, East Bradford and Bethle- 

 hem; from Franklin, N. J., and some few other locali- 

 ties furnish varieties of the species. Now Santa Bar- 

 bara claims the distinction of furnishing a new locality. 



This mineral is a peculiar combination of some of 

 the rarer metals cerium, lanthanum, didymium and 

 sometimes yttrium and traces of glucinum. silica, alu- 

 mina, lime and iron being" always present, magnesium 

 and water in nearly all of the reported analyses, and 

 occasionally manganese, soda and copper. It is quite 

 varied in its composition and appearance, and although 

 neither beautiful to the eye, nor of commercial value, 

 it is very interesting to mineralogists, and adds one 

 more species to the list of the minerals of California. 



Note. — The Annual Report of our State Mineral- 

 ogist for 1889, reports the following minerals from 

 Santa Barbara, which have not been previously noted 

 from California : 



Gilsonite, a new hydrocarbon; one pound of this 

 mineral dissolved in five pounds of turpentine gently 

 heated makes an excellent japanning varnish, applied 

 to metallic surfaces, and then baked, becomes quite 

 hard. This varnish, mixed with half a pint of oil, ren- 

 ders some fabrics waterproof, and will be flexible when 

 the varnish is perfectly dry. 



Pectolite, a silicate of aluminum, calcium, natrium, 

 found near Santa Barbara, and also in Tehama county.
