in New Zealand. We announce, too, with great satisfaction, that 
Captain Stokes, R.N. is on the point of leaving England in H.M. 
war-steamer Acheron, for the shores of New Zealand ; and that he 
possesses the means and the inclination to carry out botanical re- 
searches in the hitherto almost unknown regions of the middle and 
southern islands, by which science cannot fail to be deeply benefitted. 
DanLrxGTON's AGRICULTURAL Botany; or an Enumeration and 
Description of useful Plants and the Weeds which merit the 
notice and require the attention of American Agriculturists. 
By Wirrram Daruineton, M.D. Philadelphia, 1847. 
The amiable author of this work is already favourably known to 
science, both in England and in the United States, by his ‘ Flora 
Cestrensis’ and other botanical writings. He has here brought 
his knowledge and experience to bear on the tillage of the 
soil in the United States, and has rendered much service to the 
cause of agriculture there. An excellent Preface explains the im- 
portance of a knowledge of plants to the cultivator of the earth, 
especially of such as are useful to man and beast, and such as are 
useless or injurious, and consequently require to be eradicated. 
All these are clearly and fully described, and their properties given, 
together with much useful and interesting matter, collected from a _ 
vast variety of sources. The whole is arranged in the body of — 
the work, according to the Natural System, and a key to the Arti- — 
ficial System is also subjoined. At the close of the work we find 
the following very useful catalogues, with numbers referring to 
the pages where these plants are described :— 
1. Plants yielding esculent roots, herbage, or fruits for man. 
2. Plants yielding food, exclusively or chiefly for domestic animals. 
3. Plants yielding condiments and drinks. 
4. Medicinal plants. 
5. Plants employed in the arts, in commerce, in domestic or rural 
economy. i uelis en
