Abstract

Introduction.

Of the two rocks whose petrographical descriptions are here given, one is from the well known occurrence near Litchfield, in Maine, and the other is the rock described by Hawes* as a hornblende-syenitc from Red Hill, Moultonboro, New Hampshire.

In neither case has the writer examined the geological relations of the rocks sufficiently closely to warrant an expression of opinion regarding them. The New Hampshire locality has not been visited at all. The Maine occurrences have been visited twice, but on neither occasion were more than a few minutes spent at the several places where the rock is found.

The only excuses for the publication of this fragmentary paper at the present time are the interest that always pertains to the rare eleolite-syenites and the desire to put on record the discovery of another locality foe them within the United States.

Thanks are due to Messrs H. K. Morrell . . .
