“ A Red Zeolite from near Upsala, Sweden, (N. J. Berlin, Pogg., 
-.._ Ixxviii, 415.)—The red zeolite of Upsala resembles that of Edel- 
‘fors. The following are analyses; 1, of the Upsala mineral by 
Sjogren ; 2, of that of Audelfors by Retzius; 3, the same by Hisin- 
er; 4,as similar mineral from Fahlun by Hisinger ; and 5, an-
