Miscellanies. 175 
Some at Wethersfield have the impression of a hairy appendage 
at the heel. ‘These have the middle toe much longer, in propor- 
tion to the rest, than any that ] found. Length of the foot without 
the appendage, between 34 and 4 inches. 
I saw one track of what appears to be O. tetradactylus ; the hind 
toe being turned inward, and its extremity more deeply impressed 
than usual. Length of the foot, 3 inches. 
I have but one other class to describe. The toes vary in length 
from three fourths of an inch to two inches, and were more diver- 
gent than usual. It appears to be O. minimus. 
One specimen of O. tuberosus has the toes and claws bent under, 
as if the bird were in the act of seizing or raising something. 
On one fragment of the rock, I found the ends of two toes with 
nails, which seemed to be about two thirds the size of your O. gi- 
ganteus. 
I think I have seen the impression of toe nails as distinctly upon 
the slender toed species, as upon the other species.” 
Mr. Hanmer also describes vegetable remains of considerable size 
upon the same rock; and from his account, I suspect them to be- 
long to the tribe of Fucoides. 
I hope that you, or the gentlemen engaged in a geological survey 
of the State, will be able to visit this spot, to see whether any dis- 
coveries can be made, or to make any corrections of the above state- 
ment, that may be found necessary. 
11. Delos—Greece—titantum—iron, &c.—Extracts of letters 
to the editor, from the Rev. J. J. Robertson, Episcopal Missionary 
to Greece, at Syra and the Pireus, Nov. and Dec. 1835.—My 
chief relaxation during the past summer, was a two days’ visit to De- 
los, in.company with Lt. Stanley, who was employed for several 
weeks by the government, in forming a map and chart of our little 
island. I brought from Mount Cynthus a specimen of the granite 
of which Delos is, in a great measure, composed, and in which I 
discovered small yellow crystals of the silico-calcar-oxide of titani- 
um (sphene.). Some time after, examining a fragment of granite 
which I procured three years since from a column among the ruins 
of the so called temple of Diana at Ephesus, I found it to contain 
perfectly similar crystals. 
e director of mines for the kingdom of Greece, was at Syra a 
few months since, and took one or two excursions with him. We
