 sider may be useful at the present time."

exhibits : 

 1. Specimens of Khaki dyes with myrticolorin, the dye 

 of the Eucalypts, by H. G. Smith, f.c.s. 



Mr. Smith exhibited samples of this dye material, together with 

 specimens of wool dyed with it. These were dyed by Mr. J. A. 

 Eastwood, at the Australian Woollen Mills, Marrickville, and 

 clearly demonstrated the efficacy of this material for the purpose 

 of Khaki dyeing. When it is considered that the leaves of this 

 particular Eucalypt contain myrticolorin to the extent of over 8 

 per cent., it is at once seen that sufficient material is available in 

 New South Wales to satisfy all the requirements of Australia for 

 this purpose. Myrticolorin, which was discovered at the Techno- 

 logical Museum, is a glucosideof quercetin and is readily extracted 

 from the finely powdered leaves, as it is soluble in hot water, 

 although almost insoluble in cold water.
