village, from which I have obtained well defined six sided prismatic 
crystals of phosphate of lime from one half an inch to twelve inches 
in length, and from one eighth to one inch and five eighths in diame- 
ter. Their color is a bright asparagus green, of fine lustre, and they 
are variously terminated. Some have equal terminal faces, corres- 
ponding with the lateral planes of the prism; while others have one, 
two, and sometimes three of their terminal faces extended at the ex- 
pense of others, so as to give the crystal, in some instances, a one, 
two, three, four, and even a five sided summit of unequal faces. 
Their gangue is the white lime rock of this vicinity, in a partial state 
of decomposition, so that by the. fingers only it may be reduced into 
coarse rhombic fragments, and the crystals disengaged from their na-. 
tive bed. J. P. Youne, P. M,

9. Geological Map —A geological map of New London and 
Windham counties, is about being published by Mr. Wm. Lester, Jr. 
from the surveys of Lieut. W. W. Mather, during the late summer. 
It is to be accompanied on the same sheet by a very minute map of 
the two counties, upona scale three fifths of an inch to a mile, hand- 
somely colored, varnished, and mounted, from a copper plate en- 
graving. ; 
This survey will correct the section published in this Journal last 
year. A mica slate stratum, crosses that section, though not seen 
in place on the line of that section. It runs through Franklin, ‘Scot- 
land, Hampton, Pomfret, Woodstock, and into Massachusetts, and 
appears to be a continuation of that in Massachusetts described 
Prof. Hitchcock, on his map of Massachusetts ; but which appears 
to run out before it comes to the Connecticut ae ‘Tt: terminates 
again abruptly in Bozrah, Conn. The granular feldspar and goers, 
strata of that section, are subordinate strata to gneiss, from twe 
to thirty miles in length. ‘They terminate abruptly on the north ba bank 
of Morriss river. The contorted gneiss extends from Massachu-_ 
setts to Long Island sound, with a breadth from three to ten miles, 
and underlies the best land on the east of Connecticut river, in Con- 
necticut, except the valley of the Connecticut. The sienite of that 
section forms a bed or overlying mass, sie about twenty. or 
twenty five square miles, with greenstone, sienitic, | and granitic veins, 
traversing the strata in eyery direction arou
