* Mr. Teschemacher (in Dr. Jackson's Report on the Geology of New Hamp- 

 shire, p. 167) has given a figure of " Danaite" with Fig. 19. 

 the following angles ; M : M=112° ; a : a=121° 

 30', a" : a"=100° 15', (see the annexed figure, 

 which is Teschemacher's figure inverted in po- 

 sition so as to correspond with the usual figures 

 of Mispickel.) Scheerer has described a similar 

 cobaltic variety from Skutterud, which gave the 

 angles M : M=lll° 40'— 112° 2', a : a=121° 30'. 

 The angles do not differ essentially from those of 

 Mispickel. Rammelsberg considers iron and co- 

 balt isomorphous, and gives for the formula of the species Mispickel, (Fe, Co) 

 (Sa, Asa). (See pages 475, 476 and 568 of Dana's Mineralogy.)
