seed that agreeable aroma and taste of which advantage has been taken to prepare a drink which specially 

 stimulates the functions of the brain. To those who do not habitually drink it, coffee may become a 

 useful medicine ; it succeeds in the treatment of intermittent fevers ; it relieves asthma, and it is said 

 gout also : and it counteracts the effects of wine or of opium. Its most prevalent use as a medicine is in 

 curing headache. 



Some indigenous Rubiacete were formerly used as medicines ; thus an infusion of the flowering tops 

 of the Yellow Galium was given to nurses to increase the secretion of milk, and as an antispasmodic. 

 They are now employed in many countries, and especially in England, to give a yellow colour to cheese. 

 The Squinancy (Atptrulacynanchica) the leaves of which contain a bitter slightly astringent principle, was 

 used in cases of angina. Axperula odorata, the perfume of which comes out when dried, was praised as a 

 tonic and vulnerary; it b now only used to give a bouquet to Rhine wines, and gardeners cultivate it as 

 an edging. Madder (Jiubia titu-iuntm) grows wild in the Mediterranean region ; it is cultivated at Avignon, 

 in Alsace, and in Zealand, on account of the red colouring matter contained in the root, and which is 

 largely used for dyeing fabrics. Thia dye, in a pure state, is called alizarine. It also exists, but in less 

 quantity, in the root of the Chaya-ver, a I'ubiaceous plant, which is cultivated on the Coromandel coast. 

 [Probably the Bengal Madder (Muty'eet) is here alluded to ; it is cultivated throughout India.] 



[The above notice of the useful liufjiacea; must be largely extended ; very many species contain bitter 

 febrifuge principles, especially Exodemma, JlondeM-in, and Ctmtlaminea in South America ; as also Pink- 

 neya in Carolina, JIymen(fdicty<m in India, and the Ophwrhisa Munyo* (Karth-gall) in the Malayan Islands. 

 Ciambir, one of the most important of astringents, is the produce of Uncaria Gambir. The American 

 Itivhardmmia ncabra and others yield one valuable false Ipecacuanha, and the Psychotria enie/tca another. 

 The fruit of the Indian Itundia dumetuntm is a powerful emetic. Amongst edible fruits the Genipap 

 is that of denipa ameriratut, the native Peach of Africa is the fruit of Sarcocephalut esctdentus, and the 

 Voavanga of Madagascar that of Vanyueria edulit. El>.]
