ROSACEA. 539 
Adenanthera pavonina, a native of India, &c., produces a dye-wood, called 
Red Sandal-wood. ‘This must not be confounded with the official Red 
Sandal-wood already alluded to as being derived from Pterocarpus santalinus. 
The seeds, under the name of Barricarri seeds, are used in the northern 
parts of South America for making necklaces, &c. They are perfectly 
smooth, and have a bright red colour. 
Evrythrophleum guineense, the Sassy Tree of Western Africa.—The bark, 
under the name of ‘ ordeal bark’ or ‘doom bark,’ is used in certain parts of 
Africa as an ordeal, to which persons suspected of witchcraft, secret murder, 
&c., are subjected as a test of their innocencé or guilt. It is also used for 
poisoning arrows. It is also known under the names of Sassy, Casca, Cassa, 
and Mancona Bark. It has been lately recommended as a remedial agent, 
but the experiments of Dr. Lauder Brunton have been unattended with 
marked results. In its action it has been said to resemble that of digitalin 
and picrotoxin combined. 
Prosopis.—The legumes of P. pallida and some other species are very 
astringent, and have been employed in tanning under the name of Algarobilla. 
The legumes of P. du/cis and other species or varieties found in South 
America, &c., have a sweetish taste resembling the Carob Beans ( Ceratonia 
Siliqua), and like them are used as food for cattle, under the name of 
Algorobo ; and a drink called Chica is also prepared from them. The name 
of Chica was at first given to a fermented liquor of the Maize, but is now 
commonly applied in South America to several fermented drinks. The 
legumes of P. pubescens, under the name of Mosquit or Screw Bean, are 
largely used for feeding cattle in Arizona. A gum also exudes from the 
stems resembling Gum Arabic; it is employed in Texas and Arizona 
medicinally, and for technical purposes.
