DEPOSITS OF SCOTLAND. 387 
I have yet seen; but as Sir William Jardine is understood to 
be still engaged in figuring and describing its various footprints, 
—the only traces of former existence which it has been found 
to contain, — we bid fair to be acquainted, at no distant date, 
with all that it produces. It could be wished, however, that we 
had the result of Sir William’s labors conveyed to us in that 
cheap but yet adequate form of outline engraving in which Pro- 
fessor Hitchcock has figured the foot-tracks, reptilian or orni- 
thologic, of the New Red Sandstones of the Connecticut. 
In the Lias and Oolite of Scotland a good deal still remains 
to be accomplished. Some of their richest deposits lie scat- 
tered among the inner Hebrides, and along lochs and creeks of 
the Western Highlands, rarely visited by the tourist, and far 
from inns; and this difficulty of access has served to lock up 
in these solitudes many a curious fossil, that may be regarded 
as held in safe keeping, to reward the enterprise of our younger 
geologists. My collection contains not a few curious specimens, 
derived from these Hebridean recesses during a desultory voy- 
age in the Free Church yacht Betsey, made about ten years 
ago, — reptilian remains, fossil wood, and the teeth of placoidal 
fishes from the Oolite of Eigg, and pinnae, ammonites, and 
massive corals from the Lias of Pabba and Skye. It may 
serve to show that we are no more to argue an entire identity 
of the Oolitic deposits of Scotland with those of England, than 
of its Silurian with the Silurians of that country, — that corals, 
which are of exceeding rarity and minute size in the English 
Lias, form entire beds of great extent and several feet in thick- 
ness in the Lias of Skye. I can, however, only indicate the 
locale of some of the deposits in which these rarities may be 
found, —simply referring, in the passing, to the localities already 
indicated by Sir Roderick Murchison in his earlier papers, — 
such as the Oolites in the neighborhood of Portree, the Oolitic 
beds of Raza, and the Liassic strata of Applecross; as also to
