was a carnivorous animal or not is still, and will probably always remain, in 
great doubt. The enormous claws are in favour of such a conclusion ; but 
the evidence of the mouth is against it, which is merely furnished with common 
grinders, without fangs, or any traces of them, though that part of the skeleton 
IS entirely perfect. The neck is long enough to touch the ground. It is 
evidently of the cat kind, and appears to have been a sort of gigantic tiger. 
The breadth of the animal and the solidity of its bones are wonderfully striking." 
Can you inform your readers whether the remarkable fossil animal above 
mentioned is still in the museum at Madrid] and whether it has been seen and 
described by anyone who (from the great advances made in geology of late 
years), iS better qualified to give a more particular and scientific account of it 
than the writer of these travels ? — Qu.ery.

REVIEW. 
The Cleveland Ironstone. By J. Bewick. London : John Wealc. 1860. 
In a paper which appears in our pages this month upon the geology of 
Clevdand, the writer has made a casual reference to the volume before us, by 
Mr. Bewick, which has very lately appeared from the press ; but as it is in- 
tended to be an exhaustive treatise on the subject, it demands a more particular 
notice than we might otherwise have bestowed upon it. 
The volume shows a vast amount of observation amongst the strata of the 
district, and gives a tediously-minute history of the development of the Lias 
iron-seams in the Whitby district, where their commercial value appears first 
to have been recognised. We may date the birth of their importance, indeed, 
from the year 1838, when the Wylam Iron Company leased the ironstone on 
the estate of the Marquis of Normanby. Mr. Bewick's observations, however, 
are too much confined throughout to what is usually called the " Grosmont 
district," which has now been outstripped in point of importance by the dis- 
coveries in the neighbourhood of Guisborough. 
Wlien the writer speaks of the fossds of the Lower Lias as " the remains of 
antediluvian animals which enjoyed life, in all probability, at a date far beyond 
our chronology," he will find few geologists to dispute the probability ; but 
when he longs for " some Newton to teacli us more than we know of the birth 
of matter " the probability of his hopes beins: realized is scarcely so well 
founded. In most pages there is work for a judiciously handled pruning-knife ; 
whilst there are withiu them the elements of a scientific treatise of the greatest 
value. The inaccuracies which we notice in the present volume might easily 
be rectified, and much interesting matter added, which is uoav wanting. We 
do not certainly see any reason for " inferring" from any facts which the 
volume contains, " that the rocks upon which the Lias rests are of a very iin- 
even character," although such may undoubtedly be the case. When, again, 
the basaltic dyke, which intersects the district, is referred to as the " probable 
disturbing element" by which the rocks in Commondale are said to be uplifted 
on their edges, a glance at the phenomena there exhibited would at once nega- 
tive such a supposition : on each side of the dyke the strata retain their hori- 
zontal position, or whatever inclination they may have had previously, without
