This rock has been extensively quarried in two places, 
one in Milford, 7 miles from New-Haven, and the other 
only 23 miles from. the city. From these are obtained a 
marble which vies for elegance with any in the world. In- 
deed, in the extensive collection of marbles and porphy- 
ries in Col. Gibbs’ cabinet in Yale College, we appeal to 
those who have seen them, whether any specimens exceed, 
or even equal in beauty and richness the Verd Antique from 
Milford. The varied Sarason? and Prams of the gray, 
this marble is difficult and expense: and it is earnestly 
hoped that the patrician tot of our amet ged will 
: - for ma , , to say the 
least, are no more elegant than this, conned the proprie- 
tors of these quarries to abandon the undertaking. Spe- 
cimens of this marble may be seen in most of the dwel- 
lings of the wealthy citizens of New-Haven; and many of 
the monuments in the grave yard of that city, are of the 
Verd Antique. Several chimney pieces of it may be seen 
in wo Gir os at Washington. 
of these facts in relation to this rock, I derive from 
thai nblished accounts of it by Professor Silliman. (See 
Cleavalanis Mineralogy under Gran. Limestone, Marble, 
and Verd Antique, 2d Edit. Also, Journal Sci. vol. 2, p. 
165.) A minute account of this interesting forniation is 
still wanting; and Mr. Silliman has promised it. ae 
Jour. Sci. vol. 2, p. 166.)

Itis agreed I believe among Geologists who have ex- 
amined this region, that an extensive deposite of this rock 
exists along the Connecticut. (See Cleaveland’s Mineralo- 
gy, 2d Edit. p. 759. Eaton’s Index 2d Edit. p- 207. 
between Hartford and Quebec, p. 21, and Maclure’s Geol-

condary rock in this region, and generally lies beneath all
