"The 'History of British Sea-weeds' we can most faithfully recommend for its scientific, its pictorial, and its popular value; the professed botanist will find it a work of the highest character, whilst those who desire merely to know the names and history of the lovely plants which they gather on the sea-shore, will find in it the faithful portraiture of every one of them."—Annals and Magazine of Natural History.

"The drawings are beautifully executed by the author himself on stone, the dissections carefully prepared, and the whole account of the species drawn up in such a way as cannot fail to be instructive, even to those who are well acquainted with the subject. The greater part of our more common Algæ have never been illustrated in a manner agreeable to the present state of Algology."—Gardeners' Chronicle.

POPULAR HISTORY OF BRITISH SEA-WEEDS, comprising all the Marine Plants. By the Rev. David Landsborough, A.L.S., Member of the Wernerian Society of Edinburgh. With twenty coloured plates by Fitch. Second Edition. Royal 16mo. 10s. 6d.

"The book is as well executed as it is well timed. The descriptions are scientific as well as popular, and the plates are clear and explicit. Not only the forms, but the uses of Algæ, are minutely described. It is a worthy SEA-SIDE COMPANION—a handbook for every occasional or permanent resident on the sea-shore."—Economist.

"Those who wish to make themselves acquainted with British Sea-weeds, cannot do better than begin with this elegantly illustrated manual."—Globe.

"This elegant work, though intended for beginners, is well worthy the perusal of those advanced in the science."—Morning Herald.
