Introduction. 



Of the two rocks whose petrographical descriptions arc 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-syenite 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, hut on neither occasion were 

 more than a few minute- spenl at the several places where the rock is 

 found. 



The only excuses for the publication of this fragmentary paper at the 

 presenl time are the interest thai always pertains to the rare eleolite-
