L. W. McCay—Massive Safflorite. 371 
existence of the massive variety of safflorite be deemed ques- 
tionable, then the existence of the massive variety of rammels- 
favor of the existence of the latter. I feel sure that the major- 
ity of mineralogists will support me upon this point. Before 
it was fully settled that there was a rhombic modification of 
speiskobalt it was perfect] y proper to question the propriety of 
regarding these heavy varieties as other than tesseral in system, 
but now that the existence of safflorite has been established on 
. incontrovertible basis no doubt can, I think, be raised as to 
e right of classing them under the rhombic form. Thus our 
classification would be complete for, just as we have with ref- 
€rence to nickel: 
I. Chloanthite, tess., sp. gr. 6° 
I]. Rammelsbergite, rhomb., sp. gr. 77122 
1. crystalline. 
2. massive. 
So likewise have we with reference to cobalt: 
I. Smaltine, tess., sp. gr. 6°50 
II. Safflorite, rhomb., sp. gr. 77129 
1. crystalline. 
2. massive. 
abeled. 
The fracture is conchoidal, the structure proper finely gran- 
ular and microcrystalline. Here and there little cavities are 
Visible lined with microcrystals. The surfaces exhibit a faint 
shimmer and some pieces show a play of colors. In addition 
he smaltine already mentioned there is present a small 
quantity of crystallized quartz.
