1914. Maiden, J. H. " Notes on some Tasmanian Euealypts." 76., 1914, 
p. 20. Discusses the Eucalyptus oil question ; includes a criticism of part of the 
nomenclature adopted in the preceding paper. 
1913. Cineol determinations, Schimmel, April, 1913, p. 62. This paper 
contains the results of their own researches, and a useful bibliography. Schimmel 
refers to the researches of C. T. Bennett and F. D. Dodge in regard to Cineol, and also 
to the suggestions of W. J. Brownscombe in regard to a uniform method of testing 
various oils for pharmacopoeial purposes. 
Smith, H. G. " Note on the Paraffins of Eucalyptus Oils." Proc. Roy. Soc. 
N.S.W., xlvii, 95. The Stearoptene in the oils of some Eucalyptus species is shown 
to belong to the paraffin series. (See also Proc. Roy. Soc. Tasmania, 1912.) It was 
first isolated from the oil of E. acervula (E. ovata) of Tasmania, and later from the oil 
of E. Smithii, and from those of other species. The results indicate a mixture of two 
or more members of the series, as the melting point is hot the same with all. 
The Phellandrene question. Schimmel, October, 1913, p. 35. This is a valuable 
contribution to an important discussion. 
1914. Smith, H. G. " On the butyl ester of butyric acid occurring in some 
Eucalyptus oils." Proc. Roy. Soc. N.S.W., xlviii, 464. This ester occurs in some 
quantity in the oils of some Eucalyptus species. The acid is normal butyric, and most 
probably the alcohol is the normal form also. 
Robinson, R., and Smith, H. G. A note on the Phenols occurring in some 
Eucalyptus Oils." Proc. Roy. Soc. N.S.W., xlviii, 518. In this paper the announce- 
ment is made of two phenols in Eucalyptus oils. One of these appear to be new, and 
the name Tasmanol is proposed for it. It contains one methoxyl group. 
1915. Earl, J. C. " The Essential Oil of Eucalyptus platypus." Proc. Roy. 
Soc. Viet., xxviii (New Series), 154 (1915). The leaves were cultivated in the Botanic 
Gardens, Melbourne. The yield of oil on distillation of the fresh leaves was 1 pe? 
cent. The following is the approximate composition : 
Pinene 20-25 per cent. 
Phellandrene 10-15 ., 
Cineol 55-60 
Aromadendrene ... 10-15 ;, 
Alcohols, free, and combined as 
eaters, up to 5 ,* 
Smith, ti. G. " The Essential Oil of Eucatyp'ui Sinithii, from various forms 
of growth." Proc. Roy. Soc. N.S.W., xlix, 158. The object of this investigation wa.3 
to determine the range of variation in- the amounts of the chief constituents in the oil 
of this species, when distilled from either seedling or " sucker " growth, or from trees
