Properties. Tlie pellucid dotting of the leaves and other parts indicates 
the presence of a fragrant aromatic or pungent volatile oil, which gives the 
principal quality to the produce of the order. To this are due the grateful per- 
fume of the Guava fruit, the powerful aroma of the flower-buds of Caryophyl- 
lus aromaticus, called by the English Cloves, and the balsamic odour of those 
eastern fruits, the Jamrosade and the Rose Apple. Along with this is fre- 
quently mixed an astringent principle, which sometimes predominates, to the 
suppression of any other property. The following are some of the less known 
instances of the existence of these and other qualities. The fruit of various 
Eugenias are found by travellers in the forests of Brazil to hear very agreeable 
fruit. Pr. Max. Tr'av. 75. A fruit of Brazil, called Jaboticaheiras, brought 
from the forests to the town of St. Paul and Tejuco, belongs to this order ; it 
is said to be delicious. PI. Usuelles, 29. The young flower-buds of Calyp- 
tranthus aromatica have the flavour and quality of Cloves, for which they might 
be advantageously substituted, according to Auguste de St. Hilaire, Ibid, no. 
14. The volatile oil of Cajeputi is distilled from the leaves of Melaleuca leu- 
cadendron and Cajeputi, and is well known as a powerful sudorific, and useful 
external application in chronic rheumatism. Ainslie, 1. 260. It is considered 
carminative, cephalic, and emmenagogue, and is, no doubt, a highly diffusible 
stimulant, antispasmodic, and diaphoretic. It has also the power of dissolving 
caoutchouc. Ibid. A kind of gum Kino is yielded by Eucalyptus resinifera, 
which is occasionally sold in the medicine bazars of India. Ibid. 1. 185. 
Other species of Eucalyptus yield a large quantity of tannin, which has been 
even extracted from the trees in New Holland, and sent to the English mar- 
ket. The efficacy of the bark of the root of the Pomegranate as a remedy for 
tape-worm is well established in India. Ibid. 2. 175. The leaves of Glaphy- 
ria nitida, called by the Malays The Tree of Long Life, (Kayo Umur PanjangJ, 
“ probably from its maintaining itself at elevations where the other denizens of 
the forest have ceased to exist,” afford at Bencoolen a substitute for tea ; 
and it is known to the natives by the name of the Tea Plant. Linn. Trans.

Schauer of Breslau, who is occupied upon a monograph of those remarkable plants.
