masses, burnt iu the temples. The resin Ahmchi or Aracottchih', ob- 

 tained by incision in Guiana from the B. Ajucouchili,^ is kept fluid 

 for a longer time ; a balm is prepared from it serving for the treat- 

 ment of sores, and also employed as a cosmetic. There are a dozen 

 species of Idea cited as yielding iiseful products, but their specific 

 autonomy is often far from being proved." The Canariums of the 

 old "world are in the same case. C. mauritianum ^ furnishes a resin 

 with an odour of turpentine and camphor, the bastard Colophane of 

 Madagascar ; the Gum Carana of Amboyna is attributed to C. Syl- 

 vestre;* the resin of New Giiinea with the odour of Elemi to C. zephy- 

 rinum? In India and Java C. commune^^ whose green fruits are 

 piu-gative, gives by incision an oleo-resinous'^ juice having, it is said, 

 the same properties as that of Copaifera. The Ganuja p>innata^ of 

 India is used for tanning sldns, as are a large number of Anacar- 

 diece? Amongst these, the Sumachs are the best known in this 

 respect, especially the Tanning Sumach of the curriers [Illais corl- 

 aria^^ and the Vii'ginian S. {R. typhiiium^^). The first grows 

 wild in the Mediterranean region, in dry warm and stony places ; 

 its leaves reduced to powder are employed for tanning and dyeing, 

 whilst its flattened acid and astringent fruits were formerly used as 

 a condiment. The latter is a native of North America, but is cul- 

 tivated in our parks and gardens ; it is used, though less often, for 

 the same purposes as the former. The fruit is acid and astringent,
