Mhucilage. The solution is not gelatinized by either neutral 
or basic acetate of lead, but it slightly reduces Fehling’s 
solution, and is darkened in colour by ferric chloride and 
atinized by borax. The deep reddish brown or black gum 
Pitated by basic acetate of lead; forms an inky colouration 
with ferric chloride; a deep brown with bichromate of potash, 
md ared with molybdate of ammonia. It freely reduces 
ly soluble in water, but leaves a gelatinous portion 
dissolved. In connection with the solubility of this gum, 
observations of J. H. Maiden* on the Hucalyptus Kinos 
f interest. He found that the kino when freshly gathered 
nite soluble, but that by exposure on the tree to sun and 
e gum becomes black and insoluble. This he regards as 
to the conversion of the tannin into phlobaphenes, and in 
> that contain arabin the tendency to insolubility is pro- 
> mietarabin. The gum is usually free from fungus, but I 
e met. with three-celled, somewhat cask-shaped gonidia, 
a small hyaline portion at one end, the remains of the 
entral Provinces, are exported from Bombay. It forms 
bulk of the Amrad,t Amraoti or Oomrawatti gum of the 
bay gum merchants.

This word Amrad is probably a corruption of the Arabic hamrd, red, 
name applied to all dark-coloured gums. The word appears to © 
n first used in connection with African gums. The Acacia arabica 
are called Red gum trees; see also Pharm. Journ., 3-19-1, 
ing’s solution. This dark-coloured gum is not always 
bly enhanced by the partial conversion of that substance ~
