POPULAR SCIENCE REVIEW. 
One of the most striking peculiarities of the skull was presented by the 
premaxillary hone, which seems to have been produced downwards and 
forwards into a short edentulous beak-like process, the outer surface of 
which is rugose and pitted. Professor Huxley remarked upon the known 
form of the symphysial portion of the lower jaw in the Dinosauria, and in- 
dicated that its peculiar emargination was probably destined to receive this 
beak-like process of the premaxillaries, which may have been covered either 
by fleshy lips or by a horny beak The dentigerous portion of the pre- 
maxilla bears five small conical teeth. The alveolar margin of the maxilla 
bears ten teeth, which are embedded by single fangs, and apparently lodged 
in distinct alveoli. The summit of the crown, when unworn, is sharp and 
presents no trace of the serrations characteristic of Iguanodon ; but it is 
sinuated by the terminations of the strong ridges of enamel which traverse 
the outer surface of the crown. The teeth thus present some resemblance 
to those of Iguanodon ; but Professor Huxley regarded the two forms as 
perfectly distinct, and named the species under consideration Hypsilophodon 
Foxii. Of the lower jaw the right ramus is present ; but its distal extre- 
mity is broken off, and its teeth are concealed. On the outer surface of the 
lower jaw the centrum of a vertebra is preserved. Professor Huxley then 
stated that a certain specimen in the British Museum, which was said to be 
a young Iguanodon, was really the remains of an animal of this new genus. 
A new Locality for Eozoon in America. — It is stated in Scientific Opinion 
that specimens of this fossil have been recently found in the serpentine of 
the 11 Devil’s Den,” in Essex, United States. This discovery, resulting from 
a visit by Prof. T. Sterry Hunt, of Montreal, to the neighbourhood, will 
excite new interest in the local limestone and serpentine quarry among 
geologists, and throw additional light upon the character and age of the 
rocks of that region. 
M. d'Archiads Place in the French Academy . — On November 15 the 
Academy elected M. des Cloizeaux in the place of M. d’Archiac in the 
section of geology and mineralogy. Other candidates were MM. Delesse, 
Herbert, Fouqu6, and Hauteville. Of 48 votes M. des Cloizeaux got 40. 
Fossil Crocodiles . — M. Gaston Plante has found several of these in the 
lower part of the Meudon clay, in the spot where the Gastornis, a gigantic 
bird, had been previously discovered. — Vide Comptes rendus, Nov. 15. 
Earthquake and Yellow Fever. — The Persian Consul has written a letter 
to one of the French ministers to explain that the belief in the supposed 
connection between earthquakes and outbreaks of yellow fever is absolutely 
without foundation. 
A new Form of Calamitean Strobilus has been described by Professor 
Williamson at the meeting of the Literary and Philosophical Society of 
Manchester on October 15. The details are too numerous for reproduction. 
The strobilus differed from those of Mr. Binney and Mr. Carruthers. 
The Origin of Coal. — At one of the meetings of the Belgian Academy 
held during the past year, a paper was read by M. Benier Malherbe, who is 
connected with the mining survey of Belgium, on the various theories con- 
cerning the origin of coal. The author dwelt especially on the theory that 
the inflows of the sea which left marine deposits were only accidental. The 
paper gives tabular results of various analyses. It was reported on by M.
