* On Aromadendrin from the turbid group of Eucalyptus Kinos," Journ. Roy. 

 Soc. N.S.W., xxx, 135, 1896. An investigation of the chemistry of this new 

 constituent which occurs in the exudations of certain of the Eucalypts. This substance, 

 with Eudesmin, is responsible for the " turbidity " of certain Eucalypts. Both 

 substances occur in E. hemiphloia, and only Aromadendrin in E. calophylla, which is, 

 indeed, a convenient Kino to use as a source of this substance. 



" The Dyeing Properties of Aromadendrin and of the Tannins of Eucalyptus 

 Kinos," Journ. Soc. Chem. Industry, Nov., 1896. An investigation of the value and 

 peculiarities of these substances for dyeing purposes with various mordants. 



" On the Saccharine and Astringent Exudations of the ' Grey Gum,' Eucalyptus 

 punctata DC, and on a product allied to Aromadendrin," Journ. Roy. Soc. N.S.W., 

 xxxi, 171, 1897. The saccharine exudation is referred to at p. 182. The astringent 

 exudation is shown to contain a product allied to Aromadendrin. 



" On the absence of Gum and the presence of a new Diglucoside in the Kinos of 

 the Eucalypts," Journ. Roy. Soc. N.S.W., xxxviii, 21, 1904. The supposed 

 " Gum " of Eucalyptus kinos is here shown to be a new tannin glucoside, which is 

 practically insoluble in alcohol. On hydrolysis it breaks down into a " Kino Red," 

 and a sugar, probably isomeric with melibiose. The name Emphloin has been 

 suggested for this glucoside. 



" On Eucalyptus Kinos, their value for Tinctures and the ISTon-Gelatinisation of 

 the Product of certain Species," Journ. Roy. Soc. N.S.W., xxxviii, 91, 1904. In 

 this paper it is shown that the tannins in the exudations from the various Eucalypts 

 vary considerably in character, and that while some of the kinos gelatinise in tinctures, 

 others do not do so. The results indicate that the exudations of E. microcorys and 

 E. calophylla might be used with advantage for the manufacture of tincture of kino, 

 which would not form a jelly on keeping many years. 



" Some Recent Chemical Discoveries in the Eucalypts," Pharm. Journ. , London, 

 July, 1906. A paper read before the Pharmaceutical Conference at Birmingham in 

 1906. The various constituents recently discovered in these trees is here brought 

 down to date, and the possible economics of certain of the kinos, oxalic acid, &c, 

 considered. 



" On the Kinos or Astringent Exudations of 100 Species of Eucalyptus," Proc. 

 Aust. Ass. Adv. Science, xiv, 83, 1913. In this paper the chemical differences in the 

 kinos of the several groups are shown, together with their characteristic peculiarities. 

 The close affinity existing between the Angophoras and certain Eucalypts is demon- 

 strated through the crystalline bodies Aromadendrin and Eudesmin, thus supporting 

 previous conclusions obtained from studies in other directions. Although some of the 

 kinos gelatinise rapidly, yet, the exudations of some Eucalypts are the only ones which 

 do not gelatinise in tinctures.
