an extent in the south of France, and Italy. 0. Europsea 

 latifolla is chiefly cultivated in Spain. The fruit is larger 

 than that of Italy, but the oil is not so pleasant, which is 

 obtained by crushing the fruit to a paste, and pressing it 

 through a woollen bag, adding hot water as long as any 

 oil is yielded. The oil is then skimmed off" the water, and 

 put into barrels, bottles, &c., for use. The tree seldom 

 exceeds thirty feet, and is a branchy, glaucous evergreen, 

 and is said to be of great longevity. Some plantations at 

 Turin, in Italy, are supposed to have existed from the time

 flowers white, in large terminal panicles. O. verrucusa, 

 foliage flat, lanceolate, and white beneath, branches curi-

 blossoms are both highly odoriferous ; the plant is much 

 esteemed in China, and is said to be used to adulterate and
