3. — Mr. Alger 07i JVeiv Localities of rare Minerals, and the iden- 

 tity of species supposed to be distinct. Read before the Boston 

 Society of Natural History. 



Of new localities for rare minerals, Mr. A. credits Phacolite to 

 New York, in the form of implanted crystals or calcareous spar. 

 Color, wax or a honey yellow, with a waxy lustre; translucent; 

 no indication of cleavage; hardness=chabasite, with which it is 

 supposed to be identical. 



Yttro-cerite, has been observed by Alger in rolled masses of 

 limestone, from Orange county, N. Y., and associated with brucite. 



Ottrelite from Sterling, Massachusetts. It is disseminated in 

 small, thin plates in an argillo-micaceous slate. Color, brownish 

 black, or grayish black; lustre, semi-metallic; opake. Identical 

 with phyllitc. 



Dysluite is considered, from recent observations, to be identical 

 with automalite. 



Polydelphite, Mr. Alger coincides with Dana in the opinion 

 that it is a variety of garnet. 



Beaumontite, of Le\'y, and lincolnite, of Hitchcock, has been 

 shown to be identical with heulandite. 



Ledererite is admitted to be simply Gmelinite; the presence of 

 phosphate of lime is now supposed to be accidental. 



Washingtonite, of Shepard, Mr. A. considers to be identical 

 with ilmenite, a titanite of iron.
