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 I found. Length of the foot without 

 the appendage, between 3J 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. 



IL Delos — Greece — titanium — h'on, &fc. — Extracts of letters 

 to the editor, from the Rev. J. J. Robertson, Episcopal Missionary 

 to Greece, at Syra and the Pirseus, 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. 



The director of mines for the kingdom of Greece, was at Syra a 

 few months since, and I took one or two excursions with him. We
