406 THE EXAMINATION OP EUCALYPTUS KINOS, 



South Wales, some ladies, who saw him thus occupied, assured 

 him that they knew of nothing which cleanses the teeth so 

 quickly and so effectually as this kino. Its friability combined 

 with its astringency have doubtless secured it this reputation as 

 a dentifrice. E. rostala kino is similarly used on the Murray. 



"Apple-tree," Quiedong, 24th April, 1887. Diam., 3-4 feet. 

 Height, 80-100 feet. 



This is a comparatively dull-looking kino, having somewhat the 

 appearance of seed-lac, and the particles are equally variable in 

 point of colour. Exceedingly brittle and forming a powder of a 

 dull sienna-brown. 



In twenty-four hours it completely disintegrates under water, 

 forming two well-defined layers. The sediment is of an ochrey- 

 brown colour, while the supernatant liquid is of a dark reddish- 

 brown. The behaviour of this kino is very much the same as 

 that of E. viminalis. 



Its composition (determined October, 1888) is : — 

 Catechin and tannic acid ... . . 83-0 



Ligneous matter, &c. ... ... 1*0 



Moisture 15-3 



Ash -7 



100-00 

 Tannic acid determination (Lowenthal) 26-412 per cent. 



Eucalyptus Maideni, F.v.M., in P.L.S.KS.W. [2], iv. 1020. 

 " Blue Gum " ; called also "White or Spotted Gum." 

 Until quite recently this tree had been only cursorily examined ; 

 it was for many years looked upon as E. globulus, and surprise 

 was expressed that E. globulus had such a wide range in New 

 South Wales. The Eev. Robert Collie found it several years 

 ago between Braiclwood and Araluen, announced it to be E. 

 globulus (to which, indeed, it bears much resemblance), and this 

 statement has been copied into several books. Had not sucli 

 prominence been given to the statement, it would not now be
