off;, and the residue mixed with two or three times its 

 volume of water^ when the Darutyne crystallizes out, 

 the yield being 0.15 per cent. The crystals are soluble 

 in alcohol and 9ther but insoluble in cold water, dilute 

 acids, alkalies, and chloroform, are neutral to test paper. 

 Mr Auffray finds that it does not give the reactions for 

 Glucosides, alkaloids, acids or resin. Concentrated sul- 

 phuric acid, dissolves the crystals with a brownish colour, 

 and strong hydro-chloric acid, without colour in the cold, 

 but when allowed to boil the liquid becomes of a greenish 

 tint, depositing a green resinous substance. 



" Dr Daruty states that the effect of the herb in 

 the gangrene of wounds is very remarkable, and that its 

 results are marvellous, when given internally in cases of 

 infantile cachexia. The active principle seems to merit 

 further investigation as to its precise therapeutic value.^^ 

 " Mr Auffray also exhibits very creditable specimens 

 of sulphate of quinine and sulphate of cinchonine, pre- 

 pared in 1884 from cinchona succinibra grown in this 

 island, a good specimen of which accompanies the alka- 

 loids." 



IVatural History 



The section of Natural History was represented by 

 some well staffed and fine stag's heads exhibited by 

 Messrs. L. G. Adam, H. J. Jourdain, G. A. Dick and 

 the Hon. John Fraser. Sir G. Bowen G. C. M. G. also 

 kindly lent a nice chair made with antlers of stags, some 

 of which he himself shot at the " chasser" of the Hon. 

 C. Antelme and of Mr J. Currie. A particularly fine
