Rhodophosphite, Tetragophosphite are two partially de- 

 scribed minerals from Horrsjoberg in Wermland, Sweden, named 

 by Igelstrom. Rhodophosphite varies in color from white to red ; 

 it occurs in masses, associated with lazulite, cyanite, etc. The 

 analysis shows a small amount of SO3, but the large loss makes 

 any conclusion as to the copaposition uncertain.

Tetragophosphite is a mineral of a blue color resembling lazulite; 



it occurs in four-sided tabular crystals. One of two analyses

Bliabergsite and Ransatite are two other names given by 

 the above author to minerals from the Bliaberg in the Ransat 

 parish, Wermland, Sweden ; they occur associated with damour- 

 ite. Bliabergsite occurs in small hexagonal crystals of a reddish 

 color; hardness 4*5. An analysis gave :

 Ilam^pden Counties, Massachusetts, by Ben K. Emerson. Bul- 

 letin of the U. S. Geological Survey, No. 126. 180 pp. Wash- 

 ington, 1895. — This bulletin gives a full list of the minerals 

 occurring in the three counties named, with historical notes, 

 brief descriptions of species and occasional descriptions of crys- 

 tals, new analyses, etc. The account of the remarkable crystals 

 of stolzite and wulfenite from Loudville is especially to be noted. 



9. Recent loorks on Crystallography. — The following works in 

 this department have been received recently : 



" Grundriss der Krystallographle ftir Studirende und zum 

 Selbstunterricht," von Dr. Gottlob Linck. 252 pages. Jena, 1896. 

 (Gustav Fischer.) — This is an elementary work, embracing not 

 only crystallography proper but also physical mineralogy. It has 

 been prepared for beginners and those who may not have the 

 advantages of a teacher, and hence is limited to the more elemen- 

 tary parts of the subject. These are well presented and fully 

 illustrated.

 —This is a brief work (34 pp.) intended to be used in connection 

 with lectures and practical exercises. It is clear and simple in
