tals in a basic garnet-bearing crystalline rock, and often inclose small 
crystals of the garnet rhodolite. The mode of occurrence resembles 
in many points that of the rubies in the crystalline limestone of Burma. 
The difference in the matrix in the two instances would be of less 
significance if it could be established, as has been urged by one of the 
authors, that the Burma limestone has resulted from the slow altera- 
tion of a lime- feldspar.

Note oil a New Meteoric Iron foiaid near Iredell, Bosque County, ■ 
Texas, U. S. A. By Warren M. F^oote. (Am. J. Sci. 158, 415-416.) 
This meteorite, some three pounds in weight, presented a some- 
what rusty surface with a slight exudation of lawrencite and streaks of 
schreibersite. The cleavage, though not well marked, was apparently 
dodecahedral. An analysis showed the presence of 93.75 per cent, of 
iron. 5.51 per cent, of nickel, and slight amounts of cobalt, phos- 
phorus, and sulphur. Weak etching figures were developed by dilute 
nitric acid.

On a New Occurrence of Nepheline Syenite 171 N'ew Jersey. By 
F. Leslie Ran.some. (Am. Jour. Sci., 158, 417-426.) 
The syenyte described was found near the town of Brookville, 
where it occurs in gabbroitic trap intrusive into the Newark forma- 
tion. The exposures are not suf^ciently good to definitely establish 
the relations of the syenyte and trap, but the author considers that 
the syenyte is to be regarded as dike-like intrusions, or inclosures 
brought up from some underlying formation, rather than as a product 
of magmatic differentiation of the trap. The syenyte is of three va- 
rieties, nepheline syenyte, hornblende syenyte, and biotite syenyte. 
In addition to the description of the occurrence and characters of the 
rock a very complete chemical analysis is given.

On Graftonite, a new Mineral from Grafton. New Hampshire, 
and its Intergrowth with Triphylite. By S. L. Penfield. (Am. J. 
Sci., I5Q, 20-32.) 
The graftonite occurs in pegmatyte where it is found as a lamellar 
intergrowth with triphylite. The form of the crystals is monoclinic. 
When fresh the mineral has a delicate salmon color resembling that 
of lithiophilite, but on account of the oxidation of the iron, principally 
in the triphylite, the color is usually dark. The specific gravity is 
3.672, hardness 5, and lustre vitreous to resinous. The analysis, the 
method of which is described in outline, gave the formula R3P2OS, in 
which R stands for bivalent iron, manganese, and calcium. A study 
of its crystalline form gave an axial ratio of a:b:c=i.886:i :.582:^c=66'^. 
Its intergrowth with the orthorhombic triphylite is considered at 
length, the evidence indicating that the dome face of the latter is in 
contact with the clinopinacoid face of the graftonite. The author re- 
gards it as an original structure and one which would take a long 
period for its development. m. l. f.
