sembling in its agreeable odour the true Cinnamon, 

 which, however, comes from Cinnamomum, a Cinga- 

 . lese Lauraceous tree. We have found many Cinnamon- 

 leaves as fossils in the Bournemouth cliffs, an indi- 

 cation that that health resort has enjoyed an even 

 warmer climate than at present. 



Several species of Indigofera besides /. tinctoria (Legumi- 

 noseae) are used in the preparation of the dye. The 

 plants are soaked and beaten in vats until their 

 green colouring matter has become oxidised into 

 insoluble blue indigotin which passes into suspension 

 in the water. After settling and boiling, the blue 

 mud is dried in the sun. In 1909, ^130,000 worth 

 of this dye-stuff was imported, and ^"164,000 worth 

 was synthesised by manufacturing chemists. 



Pimento, officinalis (Myrtaceae) is the source of allspice 

 or Jamaica pepper, and from the leaves of P. acris 

 the American scent, oil of bay, is obtained, which 

 is now well known in the bay rum of hairdressers' 

 shops. 



The unopened flower-buds of Eugenia carophyllata are 

 green when newly gathered, but when dried turn 

 brown and are known as cloves. 



Pogostemon patchouli is an Indian Labiate. Its aromatic 

 oil has been less in favour as a scent with the fair 

 sex than was formerly the case. 



Tamarindus indica (Leguminoseae) pods yield a pulp 

 with laxative properties. Cooling drinks are pre- 

 pared from tamarinds in hot countries. 



Mucuna pruriens is a less desirable climbing Leguminous 

 plant from the Indies, both East and West. The 

 stiff hairs readily enter the skin, and cause an itching 

 so intolerable that the plant is known by the vulgar 

 name of Cow-itch.
