“A large portion of another skeleton of a different reptile, which 
Mr. Mantell calls the Hyleosaurus or forest Lizard, presents some 
remarkable characters,—particularly a row of terrific spines, 17 
inches long which were probably erect on the back, and in this res- 
pect realized the forms of the fabled dragons of romance. 
“ M. Agassiz spent four days chiefly in examining the fossil fishes ; 
and he regretted that his engagements as Professor in a foreign uni- 
versity compelied him to return so soon. During his visit, I had 
several times the pleasure of meeting M. Agassiz and Mr. Mantell 
in the museum, with Dr. Buckland, Dr. Faraday, Mr. Lyell, and 
Mr. Ricardo.—B.”’ 
10. Specimens from Mr. Mantell_—We have often been indebted 
to the liberality of this distinguished friend and eminently successful 
cultivator of science, for interesting specimens from the truly classical 
geological region in which he resides; among many recently receiy- 
ed are the following. 
Marsupites Milleri: two very fine specimens: the chalk being 
more completely removed with a penknife, the structure will be still 
more evident. 
A cast of the inferior or condyloid extremity of one of the largest 
femurs of the Iguanodon in Mr. Mantell’s Museum: from Tilgate 
forest. Its lower extremity is thirty four inches in circumference ; 
it is like a stick of timber 
Casts of three claws or unguical bones of reptiles, viz. claw bone 
of the hind foot, claw bone of the fore foot of the Iguanodon; the 
former were hooked or curved, like those of the Iguana, the latter 
compressed like those of the land turtle. Claw bone of a Croc- 
ile, 
. A very fine portion of a young Elephant’s tooth, from Brighton 
very rare. 
A good series of characteristic shells of the Brognor rocks, (Hamp- 
shire tertiary basin—vide G. S. E. of England,) Western Sussex. 
Fossils from Stonesfield: these in addition to the specimens for- 
merly sent, will form a good suite of the organic remains of these ex- 
taordinary deposits. _ | . 
Ribs of Iguanodon. The portions of ribs in sandstone from 'Til- 
gate Forest will serve to convey an idea of the usual appearance of 
specimens in Mr. Mantell’s collection that were imbedded in 
sandstone, and are very distinet and perfect. .
