is used in America as a refi'igerative. It is especially employed for 

 the pi-ejjaration of a drink prescribed in cases of phlogmasy. From 

 its incised bark flows a lactescent juice, soon solidifying in an acrid 

 gum-resin called Fapaw juice. The R. Vernu;^ a tree from Japan, 

 China, and India (wi'ongly confounded with the Ailantus glandidosa^ 

 under the common denomination of Japanese varnish), has also a 

 whitish juice darkening on exposure to the au", and which, dissolved 

 in a siccative oil, is used to ])repare a black varnish. It is said to 

 be poisonous, like a closely allied species, native of North America, 

 li. venenata,'^ also fvu-nishing a varnish and a wax compared to 

 that of R. succcdanca? This is well known in Japan for the wax 

 it produces, analogous to that of bees, although softer, and used in 

 that country for the same purposes, particularly the manufacture of 

 candles. The berries are boiled in water and then subnutted to the 

 action of a press which extracts this kind of tallow, imported for 

 some years past into England.* In Mexico the it. copallinum^ has 

 been considered to yield the Co2:>al of that country ; it gives a gum- 

 resin, but very different from that matter, and is more known for its 

 astringent roots, and the use -made by the Indians of its leaves as 

 tobacco, and the oil of its berries as anti-hemorrhoidal. The most 

 dangerous species of tliis genus are R. radlcans^ and Toxico- 

 dendron'' of North America, extremely acrid, contact with which, 

 and even its exhalations, produce, in the warm season, redden- 

 ing of the sliui, a swelling which is sometimes considerable, and an 

 inflammation that may be very serious. Inwardly the leaves and
