2. Ill the vicinity of some lenticular patches of a serpentinoas mineral 

 fine inclined square i)risms of pyroxene are associ iteJ with a scaly 

 white garnet, and although their external planes are converted into an 

 nnctuous steatitic mineral tlieir internal fracture are vitreous ; gener- 

 ally semi-transparent to translucent, of a greenish white color. These 

 crystals are built up of thin lamime, parallel with their lateral planes, 

 in the direction of which they cleave with great facility. The dark 

 green lamellar variety occurs in patches in a massive scapolitic ro3k on 

 lot 7, range 7, of Templeton, and at the same locality in calcite veins, 

 crystals with rounded angles, often semi-translucent, are frequently met 

 with. Fine crystals of a black color are said by Dr. Harrington to 

 occur on lot 13, range 11 of Tera]deton. 



The mineral uralite, -also mentioned by the same gentleman, is 

 found in many places in Tem[)leton, whore it apparently forms a transi- 

 tory mineral between |)yroxene and hornblende. 



Hornblende, although a common associate of the apatite veins, is 

 nevertheless never as constant as the latter mineral (pyroxene). Inde- 

 pendent of the extensive rock masses wherein this mineral forms a 

 variable ingredient, it may be said to be confined to mixed veins, com- 

 mingling with such minerals as apatite, pyrite, pyroxene, epidote, 

 scapolite, etc. The crystallised varieties are seldom observed in the 

 apatite veins, although remarkably fine prisms often occur in close con- 

 nection. On lot 12, range 1 6 of Hull, dai'k green translucent prisms 

 nearly 4 inches in length are interspersed through a band of pink 

 limestone. They are also met with in radiating groups in cavities in a 

 pyroxene rock. A pale green translucent variety, occurs in modified 

 rhombic prisms on lot 1 7, range 1 of Wakefield. A greenish gray 

 fibro-bladed variety in reticulating masses occurs at one of the openings 

 at Gem mill's mine in the same township, associated with apatite and 

 occasionally enclosing ferruginous piisms of zircon. A broken section 

 of the latter mineral measured half an inch by a quarter. The fibrous 

 variety actinolite may be frequently met with. On the 12th lot in the 

 1 2th range of Templeton, a bluish, fibrous, partly altered hoi-nblende 

 occurs on the walls of an apatite vein. 



A white fibrous Iremolite is found in the neighborhood of Old 

 Chelsea, in white crystalline dolomite.
