The proportion of Caffeine in raw Coffee beans varies 

 from about 1*10 to 1*28 per cent. It is not destroyed by 

 roasting, and as a general rule, pure roasted coffee contains 

 as much as 1*3 per cent. 



A series of photographs illustrating the cultivation of 

 Coffee in Central America will be found on the wall near 

 Case 61.

No. 316. Liberia N Coffee (CoifeaZi^/ertcajHiern), CASE 

 a glabrous shrub, native of Liberia. This plant has been 66. 

 introduced into many Coffee-growing countries, in con- 

 sequence of its more robust habit than the Coffea arahica. 

 The beans are much larger, and it thrives at lower 

 elevations. 



The total imports of raw Coffee into the United King- 

 dom from all countries during 1905 amounted to 929,459 

 cwts., of the value of £2,575,776. 



Part of this Case is devoted to illustrations of the 

 various diseases to which the Coffee plant is liable, 

 especially He^nileia vastatrix. Berk, and Br., a parasitic 

 fungus common in the Ceylon plantations, and Cemiostoma 

 coff'eellum, Mann, a small moth which has caused almost 

 the entire destruction of the Coffee plants in Dominica. 



No. 317. Fruits, w^ood, and roots of Indian Mul- 

 berry ; TOGARI of Madras (Mo7^i7ida citrifolia, L.). A 

 small tree or shrub of very variable habit, cultivated 

 throughout India chiefly for its roots which yield the red 

 dye known as Al. Cloth dyed with this substance is said 

 not to be attacked by white ants and on this account is 

 universally employed to wrap round account books of 

 bankers and shop-keepers. Specimens are also shown of 

 M. tinctoria, Roxb., which affords a red dye apparently 

 identical with that of M. citrifolia, and of M. angustifolia^ 

 Roxb., and M, umhellata, L., employed in India as 

 yellow dyes.
