spirit and bland oil, for the destruction of lice in pet dogs 

 and other small animals. 



Caraway, cardamoms, coriander, fennel, and fenugreek 

 resemble anise in their actions and uses, and may be given 

 in similar doses. These seeds are sometimes used by feeders 

 of pigs, sheep, and cattle, and by waggoners and others, 

 for improving the coat and condition of their charges. 

 Fenugreek especially is prized for such purposes, is a con- 

 stituent of various ' drinks,' and, with ground peas, maize 

 meal, locust bean, and linseed meal, forms several vaunted 

 condiments or i nourishing foods.' 



EUCALYPTUS 



OLEUM EUCALYPTI. Oil of Eucalyptus. The oil distilled 

 from the fresh leaves of Eucalyptus globulus, and other 

 species of Eucalyptus (B.P.). C 10 H 18 0. 



EUCALYPTI GUMMI. Eucalyptus gum, a ruby-coloured 

 exudation from the bark of Eucalyptus rostrata, and 

 some other species of Eucalyptus. Imported from 

 Australia (B.P.). Nat. Ord. Myrtaceae. 



The leaves and flower-buds of various Myrtacese, such as 

 cloves, pimento, myrtle, and cajuput, as well as eucalyptus 

 yield, when distilled, aromatic, antiseptic, volatile oils. 

 The rapidly-growing eucalyptus-trees, indigenous to the 

 Australian colonies, are now largely cultivated in many 

 temperate regions with the view of preventing malarial 

 fevers. 



The dried leaves yield about 70 per cent, of eucalyptol, a 

 colourless or pale, straw-coloured, liquid volatile oil, darken- 

 ing by exposure, of an aromatic odour, and spicy, pungent 

 taste, and soluble in about its own weight of alcohol. Its 

 antiseptic powers increase as it undergoes oxidation by keep- 

 ing. Other constituents are a crystallisable resin, tannin, 

 and an oil, cineol, which crystallises at 30 Fahr. 



Eucalyptus, or red gum, occurs in grains or masses. It is 

 tough, and has a very astringent taste. Cold water dissolves 

 80 to 90 per cent., forming a neutral solution. It is soluble 

 in alcohol (90 per cent.). Red gum contains kino-tannic
