In cold water it forms a solution of an orange-yellow colour, 

 something like linseed oil. Residue of a pale salmon colour, 

 with a few dark particles. Of the strength of 1 grm. to 1 litre a 

 beautiful clear solution of a dark amber colour is formed. 

 Its composition (determined October, 1888) is : — 

 Catechin and tannic acid ... ... 82*9 



Ligneous matter, &c. ... ... -8 



Moisture ... ... ... .... 15-8 



Ash -5 



100-00 

 Tannic acid determination (Lowenthal) 31*99 per cent. 

 No. 49. A sample procured by me from Mt. Victoria, N.S.W., 

 March, 1889, was perfectly fresh, and some of it was even treacly 

 when collected, though like other kinos of this group it dries 

 almost immediately. It is orange-brown of all tints, and very 

 crumbly, new as it is. I have not sufficient for a complete 

 investigation. 



It was from a tree which may provisionally be known as the 

 variety multiflora of this species. 



Messrs. Heckel & Schlagdenhauffen (op. cit., p. 151) have ex- 

 amined kinos of this species grown in the South of France. 

 Following is their analysis : — 



Eau hygroscopique ... ... 7*083 



Cendres 0*250 



Tannin et catechine ... ... 92*667 



100*000 

 on which they make the following remarks : — 



"La quantite de tannin renfermee dans le kino d' E. viminalis 

 est extraordinairement considerable, et semble en promettre un 

 emploi industriel assure."

No. 50. The collector of this kino, Mr. W. Bauerlen, states 

 that when collecting it on the borders of Victoria and New
