)2 ISLAND OF NAXOS. 
CHAP. Naxos is situate in an opposite part of the island, 
towards the north-west: the author has ever since 
regretted that his rough treatment at sea en- 
tirely banished from his recollection all thought 
of this important part of the natural history of 
Naxos; and he has the more regretted his 
inattention to it, as we are entirely ignorant of 
the geological position, association, and matrix of 
emery. Since the celebrated Tennant has dis- 
covered its relationship to corundum 1 , inde- 
pendently of its importance in a commercial 
view, and of its connection with antient history, 
it is peculiarly entitled to notice. The matrix 
of the corundum of the Camatic is a stone of a 
peculiar nature, resembling the Naxian marble 2 . 
The crystals of corundum are dispersed in it in 
the same manner as those of feldspar are dis- 
posed in porphyry 3 . The author has succeeded 
in obtaining, by the accidental fracture of the 
compact emery of Naxos, as regular an hexagonal 
form as that which may be noticed in the

marble known by the name of Coarse-grained Saline Marble." (Ste

answers to the marble of A T a.cos.
