tlXTCALYPTUS TEEES. 97 



ments, here chiefly by Messrs. Bosisto and Osborne, 

 and in London by Dr. Gladstone, in reference to the 

 illuminating power, the solvent properties, and other 

 special qualities of each of these oils. The principal 

 results of these experiments were recorded in reports 

 of the exhibition jurors at the time. Mr. Bosisto, 

 with great sagacity and a commendable perseverance, 

 but also at first with much sacrifice of capital, carried 

 his researches so far as to give to them great utilita- 

 rian value and mercantile dimensions ; moreover, he 

 patented a process by which he was enabled to derive 

 from the eucalyptus foliage the greatest amount of 

 the purest essential oil with the least consumption of 

 fuel and application of labor. Under this process it 

 became possible to produce the oil at a price so cheap 

 as to allow the article to be used in various branches 

 of art — for instance, in the manufacture of scented 

 soap, it having been ascertained that this oil sur- 

 passed any other in value for diluting the oils of roses, 

 of orange flowers, and other very costly oils, for 

 which purposes it proved far more valuable than the 

 oil of rosemary and other ethereal oils hitherto used. 

 Suddenly, then, such a demand arose that our 

 thoughtful and enterprising fellow-citizen could ex- 

 port already about nine thousand pounds to England 

 and three thousand pounds to foreign ports, though 

 even now this oil is as yet but very imperfectly known 

 abroad. The average quantity now produced at his 

 establishment, for export, is seven hundred pounds 

 per month. Alcoholic extracts of the febrifugal foli- 

 age of Eucalyptus globulus and Eucalyptus amygda- 

 lina have also been exported in quantity by the same 

 gentleman to England, Germany, and America.
