‘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.’

‘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.’
