owes its perfame to C./at>ews.' C.'anisatus'^ of Madagascar has, in 

 the dry specimens, the exact odovn oillUcium anisatum: The leaves of 

 C. Cari/ophtfUus haYe, it is said, the odour of Cheiranthm ; those of 

 C. fragrans^ menthodorum * and halsameum,^ American species, are very- 

 aromatic. C. glabellus,^ from the Antilles, has a perfamed bark, like 

 C. Eluteria, for which it is said to be substituted. C. vulnerarius ^ 

 and C. celtidifolius^ are' also stimulant and vulnerary. The last 

 especially owes its properties to a reddish juice found in a good 

 number of American species, sometimes employed for the treatment of 

 wounds and contusions, as C. abutiloides^ gossypifolius^^TJrucurana^^ 

 and. Draco, ^^ aromatic plants, whose concreted juice is compared for 

 its properties to Dragon's-blood. C. Malambo ^^ owes its name to 

 its furnishing Melambo bark, aromatic, camphorate, analogous 

 to that of Drimys, Boldu and Atherosperma, stimulant, digestive, 

 febrifuge and strengthening. In certain aromatic species of India, 

 the nature of the juice is modified by the influence of the punctures 

 of insects. It is believed that it is owiug to the action of Coccus 

 Lacca on its branches that the C. aromaiicum^* of India yields the 

 gum-lac, employed in medicine and the arts. The number of species 

 of Crpton with odoriferous juice, balsamic or- resinous, tonic or 

 exciting, is considerable in the tropical regions of the world.^^ Others 

 have very variable properties, hardly explicable, and there are 

 many Euphorhiacece of other genera the same. Thus, Euphorbia 

 Schimperiana^^ and cerebrina^'' are mentioned as dyes ; and iu- their 

 native couiitry, Abyssinia, they value Croton macrosiachgus^^ as.
