expression of partial or peculiar views. It is therefore with the greatest satis- 
faction that we call attention to the very ably compiled and exceedingly well 
got up manual, entitled ‘Lovell’s General Geography.” Both author and 
publisher merit the warmest commendations. Although intended mainly for 
primary schools, and thus illustrated with numerous engravings of characteristi¢ 
animals, important cities, &c., most useful in fixing the attention and aiding the 
memory of the young—the work, from its careful condensation and statistical 
and other tables, may be consulted with profit as a book of reference by those 
who have long bid the schoolmaster good-bye. The engravings are far in 
advance of those with which elementary geographical works are usually supplied ; 
and the views, judging from sketches of some twenty or more European and 
American cities with which we are well acquainted, are really fair representations 
of what they profess to be. The maps likewise, although necessarily upon a 
small scale, are amply sufficient fur general purposes. We may therefore truth- 
fully recommend this School Geography as the best and most useful manual of 
its kind that we have yet met with. 
On the Pre-Carboniferous Fiora of New Brunswick, Muine, and Hastern 
Canada. By J. W. Dawson, LL.D., F.G.S., &c. In this important communica- 
tion, reprinted from the Canadian Naturalist for last May, Professor Dawson 
describes various new species of land plants from Lower and Upper Devonian 
rocks of this continent; and he gives in conclusion a general summary of the 
pre-carboniferous genera and species at present discovered in British America and 
the State of Maine. The land plants, of which thirteen or fourteen are due to 
Dr. Dawson’s own determinations, amount to about twenty-one species. These 
according to the author, belong to the Conifer, Sigillariz, Calamitez, Aster- 
ophylliteze, Lycopodiacez, and Filices. Of the latter (Ferns) only two species, 
Cyclopteris Jacksoni, Dawson, and an undetermined Sphenopteris, are known. 
' The Calamitez furnish also but one form, the Calamites transitionis of Goeppert, 
likewise met with in the Devonian beds of Silesia, and in the Lower Carbo- 
niferous rocks. By adding to these the Devonian flora of New York and Pen- 
sylvania, the list of species, all belonging to Cryptogamous or Gymnospermous 
types (Dawson), amounts to about thirty. Professor Dawson observes however, 
that additional forms have been discovered in New Brunswick subsequently to 
the drawing up of his paper. 
The Metals in Canada: A Manual for Explorers, &c. By James L. Willson 
and Charles Robb, Mining Engineers. 12mo. pp. 81. Montreal: Dawson and 
Son, 1861. The compilers of this little work have just established themselves 
as mining engineers in Montreal, and they take this method of introducing 
themselves (in this capacity at least, for otherwise they are well-known) to the 
notice of the Canadian public. The work treats usefully of the various conditions 
of occurrence of metalliferous deposits generally, and gives directions for the 
carrying on of preliminary and other explorations with regard to these. It 
contains also brief notices of the more common metallic ores and economic 
minerals, with some hints on the chemical examination of these bodies. A few 
inadvertencies have crept into the compilation, such as that which states that
