Yield : 100 Ibs. of fresh brancblets and leaves gave 1.25 fluid 

 ounces. Color of the oil pale greenish yellow, odor and taste 

 mild, but both characteristic of the Tea-tree oils. 



Melulenca squtirrosa, Smith one of the Tea trees. Found 

 in South Australia, Victoria, New South Wales and Tasmania. 



Yield: 100 Ibs. dried branchlets and leaves gave 0.63 fluid 

 ounces. Color of the oil green. It resembles that of M. unci- 

 nata and M. ericifolia, but its taste is disagreeable; retaining in 

 this respect the character peculiar to the Tea-tree "oils, its flavor 

 is somewhat vapid. 



II. ESSENTIAL OILS FROM CERTAIN INDIGENOUS VICTORIAN 



PLANTS. 



These oils with one exception, are likewise all possessed of 

 medical properties : the exception being Pittosporum undulatum ; 

 and this from its exceedingly agreeable odor, is likely to meet 

 with application in perfumery. It is a highly ornamental bush, 

 easily raised from seed and blooms with great profusion, and 

 would flourish in climates similar to that of the South of France. 

 The oils of Zieria lanceolata, and Eriostemon squameus, both 

 very closely resemble oil of rue : it is thought that these plants 

 might be used medicinally as substitutes for the South African 

 bucco. The oils of Mentha Australis, M. grandiflora and M. 

 gracilis, as carminative stimulants will possibly be found equal 

 to that prepared from M. piperita. 



Atlwrosperma moscliatmn, Labillardiere Monimiaceae. The 

 native Sassafras tree. Found in Tasmania, Victoria and New 

 South Wales. A middle-sized tree. 



The oil is prepared from the bark : (the leaves also yield an 

 essential oil but no examination has yet been made of the same) 

 100 Ibs. of which dried gave 18.75 fluid ounces : it has a thin 

 unctuous consistence : specific gravity 1.040 : boiling point 446 

 the mercury rising to 473. Color pale yellow deepening to 

 yellowish-brown by age : smell oppressive and disagreeable, 

 similar to that of the oil of Sassafras of commerce, with an 

 admixture of oil of carraways: taste aromatic, and rather agree- 

 ably bitter, producing a local prickling sensation upon the tongue. 

 Physiological effects, in small doses, these are described as dia-
