the only extra-European country whose vegetable productions have been 
the subject of a complete Flora, the question is, how are travellers ix 
other regions to obtain any knowledge of the botanical productions— 
take Africa, South America, the West Indies, for example—but by en- 
cumbering themselves with such partial and imperfect Floras as exist, 
together with the bulky (yet important, but nevertheless incomplete) 
volumes of De Candolle, Walpers, Kunth, etc.? True, the volume of 
Loudon before us makes no pretence, save in the matter of England, 
to represent a Flora of any country; but since, thanks to the progress 
of horticulture, a vast amount of the more interesting and beautiful 
plants of all parts of the world are cultivated in England, they find a 
plaee here, and are frequently illustrated by figures and by a great 
amount of historical information collected from various sources. In- 
deed, too much praise cannot be given to the work for the cleverness. 
and general fidelity of the minute figures (multum in parvo), and the 
amount of knowledge to be obtained on the uses and properties of 
plants. Whenever it comes to a new edition, we trust the Natural 
Arrangement will be adopted. 
Cocks, Jony, M.D. (of Devonport): ALGaruM FASCICULI; a Collec-

The great beauty of the family of plants intended to be illustrated 
by this work, the pleasure of collecting them during the summer and 
autumn seasons on the healthful coasts of England, at those times so 
much frequented, and the facilities for studying them by the invaluable - 
writings and figures of Dr. Harvey, all conspire to render it a great 
favourite with those who are able to appreciate the works of nature. — 
The present work is a further help to the study and knowledge of the 
species. Nor is this the first of Dr. Cocks’ labours in this line. We 
I have on a former occasion noticed his useful ‘ Seaweed Collector's. 
ES Guide,’ containing plain instructions for collecting and preserving Age, 
E: and a list of all the known species and localities in Great Britain. ie 
E These two works, together with the volume of Dr. Harvey’ * “Mannal 
of British Algm' (or the more costly *Phycologia Britannica’ of the — 
same author, for those who can afford it), will render any one master —
