(Korahnisen), and then deprived of a last interior and very hard 

 shell, an operation which is called afklopping van de noot, in order 

 speedily to be steeped in lime mixed with sea-water. This method 

 of preparing the produce requires the greatest precautions, for it 

 is very delicate, and very easily deteriorated. The mace ought to be 

 thoroughly dried, but by the sun or wind ; sometimes the planters, 

 when the season is humid, secretely avail themselves of the smoking 

 frames (rook pavia pavias) to accelerate the operation ; but then the 

 mace acquires an interior colour, and sweats more slowly, when it is 

 exposed during the voyage to the heat at the bottom of the hold.—

15. Cloves of Amboyna. — But that which, above all, has made 

 Amboyna so precious, is the culture of the clove (the flower-buds of 

 the Caryophyllus aromaticus). 



In an average year, the crop of cloves may be reckoned at 250,000 

 or 300,000 lb. There are years, like those of 1819 and 1820, 

 when this quantity has been much surpassed ; but then in others, the 

 crops have been less ; in 1821, it did not amount to 100,000 lb,—

NEW PUBLICATIONS. 



1. Kosmos. By Alexander Von Humboldt. Translated by Colonel 

 Sabine, F.R.S. Fourth edition, 2 vols. Longmans, and John Murray,

 renowned work " Kosmos" ive have seen. 



2. A Manual of Botany, being an Introduction to the Study of the 

 Structure, Physiology, and Classification of Plants. By John Hutton 

 Balfour, IVLD., Professor of Botany in the University of Edinburgh. 

 Illustrated by numerous Woodcuts. One vol. 8vo. Griffin & Co., 

 London. Glasgow: Griffin & Co., J 849. Although there is a great 

 deficiency of elementary works in Zoology in this country, we rejoice,^ as 

 botanists, that we possess such Botanical manuals as those of Jussieu, 

 Schleiden, Lindley, Henfrey ; and we now add the recently-published 

 excellent Manual of Professor Balfour, which is equal, and in soine re- 

 spects superior, to the other manuals in our language at present in ex- 

 tensive circulation.

 Institute of France, &c., &c. Translated by J. H. Wilson, F.L.S., &c. 

 One vol., pp. 750. Van Voorst, London, 1849. We had much to say 

 of this classical work, but the limits of our Journal do not admit of de- 

 tail. We can only remark that the translation is good, the additions 

 Well selected, the numerous engraved illustrations very creditable to the 

 artist, and the typography beautiful. 



4. Introduction to Meteorology. By D. P. Thomson, M.D. One 

 vol. 8vo, pp. 487. Blackwoods, Edinburgh and London, 1849. This

 Meteorology. The industrious author has made ample use of the Lrc-
