leaf, which "has been used successfully in 3ij doses in the treatment of inter- 

 mittent fevers." It) appears that it is not only used medicinally in form of a 

 tincture, but also that cigars are made from the leaves, and its palliative 

 influence obtained by smoking, 



" German physicians, as appears from medical journals, have found a tincture 

 of the leaves of the Eucalyptus globuluft, or Australian gum-tree, to be a 

 remedy for intermittent fever. Dr. Lorimer gave it to fifty-three patients, of 

 whom forty-three were completely cured. In five others there was a relapse, 

 owing to a Hxilure in the supply of the tincture. In eleven of the cases quinine 

 had been used without effect, and nine of these were cured by the Eucalyptus."* 



Other species of the Eucalypti, of great value and well worthy of considera- 

 tion, are recommended by Dr. Mueller. 



E. AMYGDALiNA, LibUl, which is sometimes met with 400 feet in height ; one 

 specimen in the Dandenong ranges measured 480 feet.f surpassing in altitude 

 the gigantic Sequoias of our own State ; the wood of this species is said to be 

 well adapted for " shingles, rails, housebuilding, for the kelson and planking of 

 ships, and other purposes ;" in rapidity of growth it equals E. globulus, but is 

 not so easily satisfied with any soil. 



E. DivERSicoLOR, F. V. Mueller, a native of S. W. Australia, sometimes 

 reaching 400 feet in height, with a proportionate growth of stem. The timber 

 is excellent, and young trees are reported as doing well even " in dry exposed 

 localities in Melbourne." It is regarded by Dr. Mueller as a valuable shade 

 tree for avenues, as it makes a dense growth. 



The Eucalyptus citriodora. Hooker, a native of Queensland, " combines 

 with the ordinary qualities of many Eucalypts the advantage of yielding from 

 its leaves a rather large supply of volatile oil of excellent lemon-like fragrance." 



E. gomphocephala, Candolle, grows to a height of " fifty feet, wood close 

 grained, hard and not rending." 



Eucalyptus marqinata. Smith. " The Jarrah, or mahogany tree of S. W. 

 Australia, famed for its iudostructible wood, which is attacked neither by 

 Chelura nor Teredo nor Termites, and therefore so much sought for jetties and 

 other structures exposed to seawater, also for underground work, and largely 

 exported for railway sleepers. Vessels built of this timber have been enabled 

 to do away with copper-plating. It is very strong, of a close grain and a 

 slightly oily and resinous nature ; it works well, makes a fine finish, and is by 

 shipbuilders here considered superior to either Oak, Teak, or indeed any other 

 wood." The tree does not grow as rapidly as the Blue Gum, in the neighbor- 

 hood of Melbourne, but Dr. Mueller expresses the opinion that it would make 

 a rapid growth in a more favorable locality. 



The E. rostrata, Schlecht, the Red Gum of Victoria, is a very valuable 

 species for the " extraordinary endurance of the wood underground, and for 

 this reason highly valued for fence-posts, piles and railway sleepers ; for the
