GEOLOGICAL AND MINERALOGICAL NOTES. 191 



This occurs in irregularly banded plates in the jaspelite 

 at Saugus Centre, etc. 

 No. 89. Scapolite : Wernerite. 



In 1890 I found microscopic grains of scapolite in thin 

 sections of the hornblende-granite collected at a quarry on 

 Humphrey street, Swampscott, which is, I believe, tbe 

 only record of this mineral being detected in granite. 

 No. 90. Elasolite. 



This occurs in large irregulär crystalline masses in the 

 eleeolite-zircon-syenite at Beverly, Salem Neck, etc. 

 No. 91. Nephelite : Nepheline. 



Found in small micro-crystals in the augite-nepheline- 

 syenite at Salem Neck, Beverly and Gloucester (See Bull. 

 E. I., Vol. xxv, No. 6, p. 5, 1893.) 

 No. 92. Cancrinite. 



This occurs in minute irregulär masses in the elseolite- 

 zircon-syenite at Salem Neck vvhere it is lemon yellow in 

 color. It is more abundant at Great Haste ledge and the 

 Ram Islands, Salem harbor, where the color is grayish to 

 brown. 

 No. 93. Sodalite. 



In coarse pegmatetic masses in the elseolite-zircon-sye- 

 nite at Salem Neck, Great Haste ledge and Beverly shore. 

 No. 94. Hydronephelite. 



In radiated crystals in the elaeolite-zircon-syenite at 

 Salem Neck. 

 No. 95. Anorthite. 



A large mass of this feldspar occurs at East Point, Na- 

 hant, near the residence of Hon. H. C. Lodge. 

 No. 96. Labradorite. 



This occurs in large crystals, some of which are three 

 inches long by one and one-half inches wide, in the gabbro 

 at Bay View, Davis Neck and Lanesville in Gloucester, 

 also in porphyretic dyke rocks in various localities.
