Sir David Brewster being the Chairman of the Jury and Sir John Her-

five Principal classes of surfaces of the lea order, with their circular 
sections, right lines and lines of curv : numbers 13 to 20, rae

several helicoids and screws; 28 to 30, three retilinear screw lavas 
(not belonging to the family of pa hl just mentioned) ; 31, 32, two 
developable surfaces ; 35 to 37, refer to the theory of spherical curves 
and their polar curves, etc. The drawings are made with great ex-

8. A Catalogue of British Fossils, comprising the Genera and Spe- 
cies Aiiherto described: with references to their Geological Distribu- 
tion and the Localities é in which they have been found; by Joun Morris, 
F.G.S. Second Edition, considerably enlarged. 8vo, London, 1854.—- 
Mr. Morris’s ‘Catalogue’ affords us the results of the numerous exam- 
inations of the fossils of the British Islands, both by native and foreign 
palzontologists. ‘These researches, scattered through numerous wor rks 
—-periodical, monographic, and miscellaneous—-were of limited value 
until brought within the reach of geologists in such a compendious 
form as the work now ores us. 
However well acquainted one may be with the bibliography and nat- 
ural history of one or more groups of fossi] creatures, yf r bivalves, 
cephalopods, fishes, or any other,—and however readily he may ex- 
change his knowledge with his fellow-workers in paleontology and give 
assistance to the practical geologist, yet, fromthe loss of time in hunting 
up references and figures of fossils,—the uncertainty of memory,—the 
mislaying of note- books, and a hundred osher reasons, we well know 
that geological work cannot satisfactorily proceed without our having at 
hand a trustworthy book of reference to all described and figured spe- 
cies of organic remains. 
ome ten years ago Mr. Morris produced such a work, thereby sup- 
plying the want then felt, and which the partial lists of Fossils already 
Compiled could not meet. Since 1843 geologists have extended their 
Tesea. er new localities, and in par e organic king- 
dom previously but little studied; and an enormous increase of palson- 
t al observations h n the reayile: That these ine eg 
beid attention to the several groups 0 fossils ; and the assistance ren- 
im 3 fipeo depp ramen iit the author freely acknowledges in the 
Welce. « he assigns to each his due, and carefully notices the 
public. and ss collections from which he has gathered information 
and received assistance.
