feeder-dikes go with that of the banded amygdules, and shows that 
the amygdaloid took its place among the stratified rocks of Brighton, 
not only before their upheaval, but at a very early period of their 
history. 
Figures 1 and 2 are taken from drawings made in 1877 from rocks 
in place in the quarry on Allston St., as seen looking eastward, and 
so showing the northerly dip. In the first figure, near the middle, two 
small amygdules are shown, with a less slope in the color line than is 
usual.
