318 DESCRIPTIONS OF MINERALS. 
Carolina; Hallite from Lerni, Delaware Co., Pa.; Protovermiculite 
from Magnet Cove, Ark., are other micaceous hydrous unisilicates 
similar to vermiculite and jefferisite in exfoliation. Kerrite and 
Maconite are related to the above. They are from Franklin, Macon 
Co., North Carolina. Pclhamite is from Pelham, Mass. 
Penninite.— Chlorite in part. Pennine. 
Rhombohedral. Cleavage basal and highly perfect, mica- 
like. Also massive, consisting of an aggregation of scales, 
and cryptocrystalline. 
Color green of various shades; also yellowish to silver- 
white, and rose-red to violet. Lustre pearly on cleavage 
surface. Transparent to translucent. Lamine flexible, 
not elastic. H.=2-2%5, 3 on edges. G.=2:6-2:85. 
Composition. A specimen from Zermatt, in the Pennine 
Alps, afforded Silica 33°64, alumina 10°64, iron sesquioxide 
8°83, magnesia 34°95, water 12°40=100°46. ‘The rose-red, 
from 'l'exas, Pa., gave Silica 33°20, alumina 11°11, chro- 
mium oxide 6°85, ion sesquioxide 1°43, magnesia 35°54, 
water 12°95, lithia and soda 0:28, potash 010=101°46. 
Other ‘Texas specimens afforded 0°90 to 4:78 per cent. of 
chromium oxide. B.B. exfoliates somewhat and fuses with 
difficulty. Partially decomposed by hydrochloric acid, and 
wholly so by sulphuric acid. 
From Zermatt, Ala in Piedmont, the Tyrol, ete: <Ad@m- 
mererite, Rhodochrome, and Rhodophyllite include the red- 
dish variety from near Miask, Russia; Texas, Pennsylva- 
nia; etc. Pseudomorphs after hornblende, named Loganite, 
have the composition of this species ; and so has the mas- 
sive mineral called Pseudophite aud Allophite. 

Delessite.. A fibrous mineral near the above in composition, from 
amygdaloid at Oberstein. 
Huralite is an amorphous chlorite near Penninite, from Kura, Fin- 
land ; from amygdaloid. 
Diabantite (Diabantochronyn) is a chlorite from amygdaloid. A 
Farmington (Conn.) specimen afforded Hawes, Silica 33°68, alumina 
10°84, iron sesquioxide 2°86, iron protoxide 24°33, MnO and CaO 1°11, 
magnesia 16°52, soda 0°38, water 10:02—99°89. 
Chiorophuite is a doubtful species of chlorite, from amygdaloid. 
Ripidolite.—Chlorite, in part. 
Monoclinic. Similar in cleavage and mica-like character 
to penninite, and also in its colors, lustre, hardness and 
specific gravity.
