No. 236. Pods and flowers of Acacia farnesiana, 

 Willd. A shrub or low tree widely distributed in 

 America, East and West Indies, Australia and Africa, and 

 often planted for its ornamental character or for the sake 

 of the perfume from its flowers, known as Cassie. It is 

 cultivated largely on the perfume farms of the South of 

 France, and thrives better at Cannes than in any other 

 part of Europe. A model of a still used by the 

 perfumers for distilling flowers is here shown, also frames 

 upon which a layer of fat is spread, over which the 

 flowers are sprinkled, the perfume being absorbed by the 

 fat. The perfume from flowers is also obtained by 

 spreading cloths saturated with the finest olive oil over 

 the wire frames here shown, and laying the flowers upon 

 these cloths, leaving them for a long time till the oiled 

 cloths have absorbed the perfume ; the oil is afterwards 

 obtained from the cloths by means of a screw press. 



No. 237. Babul Gum from Acacia arctbica, Willd., 

 a moderate-sized tree found in India, Arabia, Egypt, 

 Tropical and Southern Africa. Numerous samples of 

 gum are shown of very different character, some in large 

 agglutinated blocks, nearly black in colour, others in 

 small roundish colourless tears. It forms some of the 

 East Indian Gum Arabic of commerce, but is mostly 

 mixed with other gums. In India it is employed in 

 native medicine, dyeing and cloth printing. The wood 

 is very durable if well seasoned, and is used in India for 

 wheels, sugar and oil presses, rice-pounders, agricultural 

 implements, &c. The bark is used for dyeing and 

 tanninsf. In Scinde and Guzerat large quantities of lac 

 are collected from the tree. 



No. 238. Gum Arabic, obtained chiefly from 

 Acacict Senegal, Willd., a tree about 20 feet high, native 

 of Senegal and the Soudan. The gum exudes from the 

 branches, " principally during the prevalence of the dry 

 *' desert winds from the north and east, which blow in 

 " the winter after the rainy season," In some districts 

 the issue of the gum is facilitated by incisions. The best
