The Rev. B. Powell, Savilian Professor of Mathematics in the University of 
Oxford, and author of the “ History of Natural Philosophy,” in Lardner’s Cyclo¬ 
paedia, who has reviewed the series at some length in the “ Dublin University 
Magazine,” after some general observations on the whole subject, thus remarks:— 
“They are productions having for their express object the diffusion of a sound 
and elementary knowledge of the main branches of Natural Science. They are 
designed for all classes of beginners; whether of one grade or another, they are 
intended to be alike available to the mere humble seeker after instruction, who may 
peruse them upon his contribution of his weekly pence, in the unpretending 
reading-room of the Mechanics’ Institute, in an obscure country town ; or to the 
young inquirer, who, with greater advantages and leisure, is devoting his opening 
faculties to the happy task of at once enjoying gratifications of the purest kind, 
and at the same time exercising and invigorating those faculties, and enlarging their 
capacity for such enjoyment to a higher and increasing, and as yet unconceived 
extent.” 
“ In promoting the important object of making Natural History a branch of 
education, nothing can be more desirable than the production of books like this 
before us, which unite profound knowledge with a just appreciation of what is 
required for instruction, enlarged philosophical views, and accuracy of detail, with 
an intelligible and pleasing style, and freedom from all repulsive technicalities.” 
— Inquirer. 
“ These works display a fulness of knowledge, with great powers of popularly 
conveying it, and a clear and methodical general arrangement, as well as a judicious 
selection of particular facts for the purpose of illustrating general principles.”— 
Spectator. 
“ The present work has merits of its own, that render it exceedingly suitable as 
a text-book for the instruction of youth. It is simple enough to be a first book to 
those who are fit to enter on the subject at all, and it is so full of interesting 
examples, and carries out the principles so far as to convey, not merely apparent 
but real and substantial instruction. In making his book copious and complete, 
while he keeps it level to the comprehension of beginners, we think that Dr. 
Carpenter has been acting on a most important view of scientific instruction, which 
the mass of popular writers have very slightly adverted to. At the same time that 
we think the treatise happily constructed for beginners, there is so much of novelty 
and interest in the laying out of the doctrines, in the rich and accumulated illus¬ 
tration of them, and in the new view's occurring here and there, as to make it well 
worthy of the perusal of those already familiar with the science. And for clearing 
up and fixing the imperfect conceptions of the half-initiated student, we can safely 
give it our most sincere recommendation .”—Westminster Review.
