ABSTRACT OF PROCEEDINGS. : wx. 
The principal sugar contained in some of these exudations was 
found to be raffinose (melitose), and is identical with that obtained 
from beet. Naturally formed Eucalyn was also found. The 
new substance “Eudesmin” was isolated from the kino in fine 
crystals 5-6 mm. in length. Aromadendrin is not present in this 
kino. A true mordant yellow dye-stuff was isolated from the 
leaves of the “ Red Stringy Bark” of N.S. Wales, Hucalyptus 
macrorhyncha, F.v. M., and has also been investigated. The 
author has named it Myrticolorin., It is somewhat allied to 
Aromadendrin found in some Eucalyptus kinos. Myrticolorin 
belongs to the quercetin group of natural dyes ; it can be obtained 
in abundance, and with a minimum of trouble, and hence its dis- 
covery may be of commercial importance. 
3. “On the Essential Oil and the presence of a solid Camphor or 
Stearoptene therein, of the Sydney ‘Peppermint,’ Hucalyptus 
Piperita, Sm,” by R. T. Baker, F.L.S., Assistant Curator of 
the Technological Museum, and Henry G. Smira, F.CS.,

This is the commencement of a projected research on the oils 
of each species of Eucalyptus in New South Wales. The essen- 
tial oil contains 24-59% of Eucalyptol, a rather low percentage 
compared with that of Z. glcbulus, and much less than that of 
E. punctata. An important discovery concerning this oil was the 
Presence of a stearoptene or solid camphor in the fifth fraction 
boiling between 265° and’ 270° ©, It was detected first on the 
corks of the bottle containing the distilled oil. The stearoptene 
crystallises in acicular forms, and most probably belongs to the 
thombic system. It has not yet been isolated chemically. This 
Species is the Eucalyptus from which Eucalyptus oil was first 
obtained, viz., in 1788, by Dr. White, of the first fleet under 
Governor Phillip. ‘That officer spoke highly of the therapeutic 
Properties of the oil. The yield of oil is good, ‘784 per cent. being 
obtained from leaves and branchlets. The oil is levo-rotatory
