poisons, and the roots are also known as Bikli. A. lycoc- 

 tonum, yellow-flowered Wolf's-bane, a common plant in the 

 [NTorth of Europe, is also poisonous. Linnaeus, in his History of

 eaten by cattle it increases abundantly." 



Adam's Apple, a fanciful name given to varieties of the 

 fruit of the Lime, belonging to the Orange family. 



Adam's Needle, a common name for the different species of 

 Yucca, a genus of the Lily family (Liliacese), native of Mexico, 

 Southern United States, and other parts of America. Some 

 species are stemless, while Y. gloriosa and others have palmid 

 stems, which under favourable conditions in this country attain 

 the height of 4 to 6 feet, and 6 or more inches in diameter. 

 They are often branched, each branch being terminated by a 

 tuft of lanceolate or sword-shaped leaves, from which rises a 

 panicle 2 to 3 feet high, bearing large pendulous white flowers. 

 All the species contain a large quantity of fibre in their leaves 

 which is extensively used in the countries where they are

 occupies extensive tracts of country ; its fibre is strong, and 

 used as a substitute for hemp.

 generally found growing near the sea, abundant on the Sunder- 

 bunds of the Ganges. Its milky juice is very acrid, blisters 

 the skin, and is much dreaded by woodcutters. The wood is 

 used for making charcoal, but the smoke is injurious to the 

 eyes. It is also a native of some of the Polynesian Islands, 

 where it is as much dreaded by the natives as the manchineal of 

 America. In Fiji it is employed for the cure of leprosy, its
