‘Dr. HARTWIG’S volume is a perfect model of the popular treatment of a

large subject. It is at once full, clear, concise, and attractive; and

it possesses the merit, absolutely unique as far as our experience goes

in works of this kind, of being readable from end to end. Though closely

packed with details—sufficiently so indeed to be a good, though of

course not an exhaustive, book of reference for practical use—these are

so well selected and arranged, so concisely related, and so carefully

subordinated to general views, that they never produce any sensation of

weariness, monotony, or confusion. There are some admirable

chromoxylographs, and an infinitude of excellent woodcuts scattered up

and down the pages with a profuse hand. In short, _the Sea_ has received

from Dr. HARTWIG a recommendation to public attention which can scarcely

perhaps increase its popularity, but which will certainly enable many of

its admirers to regard it with a more enlarged and intelligent

admiration. The title, large as it is, does the work some injustice, for

we are apt to forget the _Sea_ itself in the _Living Wonders_ which it

nourishes; and we scarcely include, in our conception of life, the

vegetation of the ocean. This, however, is no fault of Dr. HARTWIG’S;

for he fairly exhausts his subject. The first seventy pages are devoted

to a very clear account of the general features of the sea. Its extent

and depth and colour, its coast-line and currents, the height and

velocity of its waves, the theory of its tides, the mighty circulation

whereby the life-currents of the earth rise in evaporation from the

ocean surface, are dispersed through the upper regions of the air, are

condensed in rain, and, trickling through the soil, return in rivers to

their native reservoir, are all set forth with great skill and beauty of

language. Dr. HARTWIG then passes on to the inhabitants of the sea.

First come the “hugest of living things,” the _Cetaceans_, with their

kindred the seals and walruses—animals which in their anatomy and habits

form a curious link between the tribes of earth and water, and in their

vast size and outlandish forms seem, at least in fancy, to connect the

present age with distant geological periods.... Penguins and auks and

albatrosses next come under our notice: then turtles, the only modern

representatives of the ancient saurians; then follows a description of

many of the more curious fishes—among which we notice some singular

creatures with fins and tails and gills, which can not only live for

days out of water, but actually creep up trees and catch insects. Crabs

and barnacles, worms and molluscs, star-fishes, sea-urchins, coral-

polyps, and our familiar friends the sea-anemones, all come in for their

fair share of attention. Even the microscopic foraminifera and

diatomaceæ are included: one chapter is given to marine plants, and

another to the primitive ocean; while the whole is appropriately closed

with a brief sketch of the progress of maritime discovery. And all this

is packed into an elegant volume of 400 pages. Never, surely, was such a

mine of information presented in so pleasing a shape. Dr. HARTWIG has

skimmed the very cream of marine science, and thrown all its daintiest

morsels into a single attractive dish.’

GUARDIAN, First Notice.

‘This is the third edition, considerably enlarged, of the first and best

of Dr. HARTWIG’S beautiful and popular volumes on natural history. The

size of the book is increased by a hundred pages; a good deal of it is

remoulded; two whole new chapters have been added, one on Marine Caves,

the other on Marine Constructions, such as Lighthouses and Breakwaters;

some of the old illustrations have disappeared, but their place has been

supplied by more and better; so that the new edition really amounts to a

recasting of the entire book. It was a very good book before; it is

better and more complete now. Whether we regard the letterpress or the

numerous illustrations, it takes a rank second to none among ornamental

and popular books of science.’ GUARDIAN, Second Notice.

THE TROPICAL WORLD: a Popular Scientific Account of the Natural History

of the Animal and Vegetable Kingdoms and the Equatorial Regions. With

8 Chromoxylographic Plates and about 800 Woodcuts. 8vo. price 21_s._

-------------------------

‘This work well deserves popularity, and is just the book to interest

young persons who have the sense to perceive that the truths of nature

are not only stranger but far more profitable than some fictions. All

that intelligent women and children desire to know about the tropics

will be found here—the aspects of nature, the rivers and coasts, the

great sandy deserts, the gigantic vegetation, and the animal denizens

from insects to apes; but excluding the tropical varieties of man.’

MEDICAL TIMES _and_ GAZETTE.

‘Dr. HARTWIG has followed up his admirable book on the SEA by another,

not less admirable, on the _Tropical World_. The same wide erudition,

vivid powers of description, and happy intermixture of popular and

scientific treatment are displayed in it; and its pages are adorned by

the same profusion of elegant illustration. Within the tropics Nature

revels in her wildest luxuriance: bird, beast, reptile, and plant take

there strange forms and colours, or attain unusual magnitude. Dr.

HARTWIG has steeped his pen in the glowing atmosphere of the tropics;

and with it, as with a wand, he leads us through successive regions of a

sunny fairyland teeming with beautiful natural objects in inexhaustible

variety, changeful and brilliant as the effulgent landscapes amid which

they flourish.’

GUARDIAN.

‘The tropics give us something like a picture of the antediluvian world.

The heat and moisture, with the consequent luxuriance of vegetation in

tangled overgrowth, the violence of the storms, and the ferocity and

hideousness of many animal forms, mark out these equatorial regions as

very striking, very picturesque, very interesting, but not very

agreeable as a residence. Unless we are young, robust, and adventurous,

it is pleasanter to read of such regions in our milder Europe, and to

visit them in imagination, following the adventures of others. And this

journey Dr. HARTWIG enables us to make through his excellent

compilation.... We have indicated the nature of Dr. HARTWIG’S book, and

have only to add that it is compiled with great skill, and written in a

clear and agreeable style. It is seldom that we have occasion to notice

a more satisfactory work of the class to which it belongs.’

SATURDAY REVIEW.

‘We ought not to conclude these gleanings without a brief notice of Dr.

HARTWIG’S popular book. There are those who look with contempt on

popular science of all kinds, and regard with undisguised aversion such

compilations as the one before us. We do not share these feelings in the

least degree; on the contrary, we welcome most heartily such

introductions to the study of natural history. True, they may be

sometimes of little scientific value, but they are very useful stepping-

stones to something more solid. They are more especially intended for

the young, but those of mature years may derive much profit by a perusal

of many of these works, and even the naturalist may read them with

pleasure and instruction. The numerous beautifully illustrated and

carefully compiled works on natural history, such as the _Tropical

World_, together with the _Sea and its Living Wonders_, by the same

writer, and several others which have appeared within the last few

years, are an encouraging sign of the growing interest which the rising

generation takes in the study of the great Creator’s works, and we

heartily wish them Godspeed.’

QUARTERLY REVIEW.

_Works by the same Author._

THE HARMONIES OF NATURE,

OR THE UNITY OF CREATION.

With 8 full-page Engravings on Wood, from Original Designs by

F. W. Keyl, and about 200 Woodcuts in the Text.

8vo. price 18_s._

‘As a sort of abridged KOSMOS brought down so as to include the latest

discoveries of science, Dr. HARTWIG’S _Harmonies of Nature_ is admirable

for the view it gives of the order of nature as we can at present

conceive it. Such a work enlarges and clears our conception of the

universe, and we can heartily commend both the ability with which the

facts are elucidated and the reverential spirit with which they are

treated.’

GLOBE.

‘Dr. HARTWIG’S book at first looks like a system of natural history: it

swarms with woodcuts of zoology and comparative anatomy. But it properly

belongs to general psychology; for its object is comparison and

deduction, and a view of the chain of being, which ... after some

general cosmogony, begins at the lowest phases of vegetable life and

ends with man.... The book is very interesting, and fills a very useful

place.’

ATHENÆUM.

‘The nature of Dr. HARTWIG’S _Harmonies of Nature_ will perhaps be

better understood if we call it a popularised KOSMOS. Beginning with the

starry heavens, the Author leads us through air and ocean, and shows in

broad outline how material nature is adapted to the organic life which

fills it. He then traces out the ascending grades of organic life itself

from plants to sponges and jelly-fishes, and from them up through

molluscs, insects, fishes, birds, and mammals, to man himself, the crown

of all. This great outline is filled up with sufficient detail to give

it substance and interest. It is traced with a flowing and expressive

pen, and illustrated by an elegant and abundant pencil. Those who have

seen Dr. HARTWIG’S former works will be satisfied to know that this is

no unworthy companion to them.’

GUARDIAN.

‘The _Harmonies of Nature_ will add to its Author’s well-deserved

reputation as the most correct and philosophic as well as the most

entertaining writer of the day on popular natural history. Unlike most

of the compilers of this class of works, Dr. HARTWIG has a very

extensive knowledge of his subject, a knowledge sufficient to enable him

to present to his readers a well-arranged work, that may be read with

profit as well as with pleasure. The object of the work is to point out

and illustrate the unity of plan which prevails throughout creation....

Compared with the popular natural histories current in France and

England, the works of Dr. HARTWIG are of much higher excellence; and for

those readers who desire to know something about physical science

without becoming painful and diligent students, no volume can be

recommended as more delightful than the _Harmonies of Nature_.’

_The_ FIELD.

--------------------------------------------------

THE POLAR WORLD;

A POPULAR DESCRIPTION OF MAN AND NATURE IN THE ARCTIC

AND ANTARCTIC REGIONS OF THE GLOBE.

With 8 Chromoxylographic Plates, 3 Maps, and 85 Woodcuts.

8vo. price 21_s._

‘The appearance of Dr. HARTWIG’S book at this time is very opportune.

There is every reason to believe that public attention will be directed

during the next ten or fifteen years to the Polar regions and the

contemplated expeditions to them. Whether or not the suggestions are

carried out which were made at the recent meeting of the Geographical

Society for an educating trial trip to the Arctic coast, there can be no

doubt that there will be an expedition in 1881-1882 for the purpose of

observing the transit of VENUS in the Antarctic Seas. Sabrina Land and

Possession Island are spoken of as suitable stations for the

observations. Most readers would have to refer to their maps, or to

almost forgotten books of Antarctic travel to make themselves acquainted

with those localities. Dr. HARTWIG’S volume gives maps, description, and

history of all that is known concerning these icy regions in a few

compendious pages.... Like Dr. HARTWIG’S former works, the _Polar World_

is a model of interesting and authentic compilation. Starting from

Iceland, he takes us round the lands which circle about the North Pole,

describing their natural features, the people who inhabit them, the

birds, beasts, and fishes, and the scanty vegetation, which is

frequently little more than varieties of mosses and lichens. The same

plan is followed in the regions of the South Pole. In his treatment of

all these subjects the Author combines the qualities of a clever

historian, a well-informed geographer, and a correct naturalist.

Gathering up all the information supplied by numerous explorers, he has

presented to us the result in a beautifully illustrated volume,

containing a clear, concise, and faithful description of man and nature

in high latitudes. The work will be exceedingly useful as well as

interesting to the naturalist, as nearly every chapter in it contains

careful accounts of the animals peculiar to the regions described....

The _Polar World_ will add greatly to the already well-deserved

reputation of the Author.’
