244 Localities of Minerals. 
REMARKS. 
‘We have been familiar with the Rhode Island anthracite, 
and with the formation of rocks in which it is found; and, long 
since, observed the fact mentioned by Dr. Webster. The as- 
bestos is often in the form of the most delicate ren 
frequently blended also with the slate rocks, which form 
roof and pavement of this coal. A specimen now lies oes 
oe in which a complete vein of this amianthus with fibres, 
early two inches in length, connects and pervades a mass of 
i, supposed to be of the transition class. 
Similar facts are mentioned also by Dr. Meade, in his account 
of the Rhode Island coal. 
RED PYROXENE AUGITE. 
Extract of a letter to the Editor, from Dr. H. H. Hayden of 
Baltimore. 
ie very lately discovered a couple of small specimens 
of the transparent red pyroxene, resembling fine crystals 4] 
titanium, which I, at first, mistook it for. One of them is com 
tained in the middle of a large crystal, like the rubellite in the 
green tourmalin of Massachusetts, but it is not the same sub- 
tance. The pyroxene, which I have reference to, is ™ 
olive-coloured epidote of some, pistazite of others, but rese™ 
les, in this instance, the sahlite; the crystals being divisible 
longitudinally. Some of them are five inches long, a0d- 
an inch in diameter, ASO and double; that is two inl 
together, as described by Brochant in particular. 
Some other localities, of which we have received notice’ 
may be mentioned in a future number.
