4. Lamellar Hornblende. Good specimens are found in 
_ Holland Mass. (aton.) Also in Leverett, Sunderland, Con- 
way, &c. of a black colour, in Shutesbury it is green. 
{t is found in sienitic granite and gneiss, in scales that are: 
easily mistaken for black mica. 
2. Fibrous Hornblende. At Leyden, the fibres very fine. 
Also near Bellows Falls, extremely beautiful, associated with 
quartz. Also in Shelburne, Conway, Goshen, &c. in mica 
slate, in large and broad fibres or lamellae. 
3. Fusciculite. This is composed of fibres, or ratherin many 
instances, of lamellae, frequently more than ;; of an inch 
broad, diverging at both ends, soas to o¢cupy usually, as man 
as 60° of a circle.’ These lamellae are commonly inserted 
perpendicularly to the folia of the slate in which they occur. 
and are applied to each other by their broader faces, being 
bent outwards on both sides. somewhat like a bow, and pre- 
senting elegant and very perfect fascicles. Tne fibres or 
lamellae, scarely, if ever, cross one another; yet some- 
times they diverge in nearly straight lines, and sometimes 
are so much curved as to resemble very exactly a sheaf 
of grain when standing erect. (See Plate 9,) The figure in 
the plate does not give a representation more regular or dis- 
tinct than inany of the most perfect specimens present. The 
length of the fibres or lamellae varies from one to four inch- 
es. Itis found i mica slate and talco-micaceous slate ia 
Hawley, Plainfield. and.Conway. Probably this variety is 
comprehended under Fibrous Hornblende by Cleaveland ; 
and perhaps specimens as perfect as those described above 
are not unfrequent. But so exact and striking an instance 
do these exhibit of the fascicular structure of minerals, that 
I a not resist the temptation to denominate them Fusci-. 
cuirte, 
4. Hornblende Slate. For an account of this, see the Geo- 
logical part of this sketch. 
53. Actynolite. At Saybrook, and near N. Haven in ser- 
pentine. (Silliman.) Also at Litchfield. (Brace.) Also at 
Middlefield. (Dewey.) Also at Hawley. (Eaton.) Also at 
Cummington. (J. Porter.) Alsoat Windham in compressed
