Prof. Owen stated that, from the evidences afforded by the photographs, he finds 
the dentition of this upper jaw to consist of three incisors and five molars on 
each side, of wliich the first appears to be a premolar and the rest true 
molars, thus, i. ilf , c. Hz!!, p. Ill, ni.tzl ; agreeing, iu this formula, with Macropu$ 
and Diprotodon, The modifications of this dentition resemble those of the latter 
genus in the retention of the premolar, after the last true molar has come into its 
place, and in the superior size of the first, as compared with the second and third 
incisors. He then described iu detail the sockets of the incisors, and the form 
and conditions of the molar teeth, which are highly characteristic of the marsu- 
piality of this huge and most strange extinct quadruped. The cranial characters 
which were next described, equally elucidate this affinity. The peculiar facial 
bones were then described in detail ; that portion in advance of the orbits forming, 
as it were, a short pendunculate appendage to the rest of the skull, increasing in 
a remarkable manner in both vertical and lateral extent as it approaches the muzzle, 
but not offering any evidence of having borne a nasal horn, as thought to be pro- 
bable by Mr. Macleay. The cavity of the nose is divided by a bony septum — a 
character which Prof. Owen has lately found to exist also in a rare species of living 
Wombat — to a much greater extent than in other known marsupials. Wholly 
concurring in Mr. Macleay 's conclusions as to the marsupial nature of the fossil 
in question, Prof. Owen does not think that it exhibits evidences of a generic 
distinction from Diprotodon. The Professor suggested, however, that probably the 
lower jaw, when found, may show some peculiarities of dentition and proportions 
similar to those on which he has founded the genus Notolherium. 
Meetings or Field Cldbs. — Three of the West of England Natural History 
Field Clubs have arranged to meet at Ledbury, Herefordshire, on the 3i-d of June 
— viz., the Herefordshire (Woolhope), the Worcestershire, and the Malvern. In- 
vitations will also be sent to the Field Clubs of Gloucestershire (the Cotswold), 
Warwickshire, and Tyne Side.

Oeology made Easy, or the Old and Neio World. By H. Smith Evans. 
London : Read & Co. Small 4to. 
Two kinds of books there are which should ever be written as well as possible, 
but of one of these kinds we have an abundance in which the rule is not followed. 
We confess we never took up a book with kinder feelings towards it than we did 
the little yellow-covered work before us : we liked its appearance and we 
liked the title, "Geology made Easy," and we even overlooked the error in 
its secondary title, and good-naturedly mistook the flourish for an S. We 
saw at a glance clearly printed pages, modest looking lithographs, and an accumu- 
lation of what appeared to be facts, and we sat down to read it through in the 
expectation of being thoroughly delighted. Inaccurate in language — subjected, we 
should think, to no revision through the press — and with statements most 
loosely and incorrectly made ; we put the book down with a feeling of actual pain. 
With repetitions of such blunders as " stratums ''and " modules," with " trebolite," 
and other instances of mis-spelling, impossible to reconcile even with the phonetic 
system, — with facts so oddly stated, as one, for instance, in the table of intensity of 
winds, where a brisk gale of fifteen miles an hour is called pleasant and one 
of twenty miles an hour " very ditto," with others so much at variance with what 
geology teaches us, as that at page 70, where we are informed of the probability of
