Dr. Rabuteau states that the leaves contain no alkaloid. 

 Count Maillard de Marafy from experiments instituted by him, 

 announces that the leaves can be used as a substitute for sumach. 

 The tincture is stated to be an excellent remedy against ague 

 and intermittent fever, especially that kind which is often epi- 

 demic in marshy districts, and Spanish physicians have pro-

 to in above list possess powerful tonic and diffusible stimulant 

 properties, performing remarkable cureo in cases of chronic 

 catarrh and dyspepsia, and soaic form an excellent antiseptic 

 application to wounds. From this it will be seen that this Eu- 

 calypt may become of very great importance in a medicinal point

 respects it would not be surprising if many other of the species 

 were found to possess ccjually important properties.

 the various purposes of the shipbuilder, millwright, wheelwright, 

 coachmaker and carpenter ; and many, from the great beauty of 

 their duramen, and the very high and beautiful polish which 

 they are capable of receiving, are justly favorites with the cabinet 

 maker. 



The iiiahcv of Eucali/ptiis marginata, Smith — the Swan River 

 or West Australian mahogany, or mahogany eucalypt (restricted 

 to Western Australia), is worlhy of special notice, from the 

 wonderful property it possesses of being absolutely impervious to 

 the inroads of the Limnoria, Teredo and Chelura : a property 

 which eminently adapts it for the construction of wharves, jetties,
