Strontianite occurs sparingly in cavities in concretionary masses 
of limestone contained in the Utica shales of St. Helen’s Island, 
Montreal. Acmite is shown by Dr. Harrington to be an impor- 
tant constituent of the nepheline syenites of Montreal and Beleeil.

11. Allanite from Topsham, Maine ; by F.C. Roprnson. 
(Communicated.)—Some time ago there was brought to my no- 
tice a peculiar, and to me then unknown mineral which a student 
had discovered in the granite on what is known as “Sprague’s 
Hill,” Topsham, Me. We have just completed an analysis of 
it, and proved it to be allanite. It occurs in the above locality 
in considerable abundance and in the form of brownish crystals 
partially decomposed, and looking like rusty nails driven into 
the granite. Occasionally fair crystals are found. Up to the 
time of its discovery no cerium mineral was known to occur here, 
occur in the same locality as the allanite, but is associated with 
columbite and gahnite. Other minerals of this locality are also 
being analyzed by us and notices of them will be published from 
time to time. The analysis of the allanite was made under my 
supervision by J. Torrey, Jr.
