GUMS, RESINS, AND KINoS, 
AlGU WaSe 
DEFINITIONS. 
Tue following definitions are complete enough for ordinary pur- 
poses :— 
(2) A gum is entirely soluble or swells up in water, but entirely 
insoluble in alcohol (commonly called “spirit”’). Z.g., “ Wattle- 
gums.” (Acacia.) 
(4) A resin is entirely soluble in alcohol, but entirely insoluble 
in water. Z.g., “Pine resin.” (Frenela Endlicher?.) 
(c) A gum-resin is intermediate in character between a gum 
and a resin, that is to say, it is partly soluble in water and partly 
soluble in alcohol. Z.g., the gum-resin of Prttosporum undulatum. 
(d) A kino is the astringent inspissated juice of atree; excel- 
lent examples are afforded by the various species of Eucalyptus. 
Important note. The classification of the exudations from 
some of the species is only intended to be provisional. In the 
absence of some of the products which I have had no opportunity 
of examining, I am unable to say, for instance, whether some of 
them should be grouped as “ gums,” or as ‘‘ gum-resins.”’ 
1. Acacia SPP, N.O., Leguminosz. 
“ Wattles.” 
These gums are exported for adhesive purposes, for cotton- 
printing, &c. A large number of Acaczas yield them in greater 
or less quantity. Speaking of wattle-gum in general, Bentley and 
Trimen (Medicinal Plants) say: “It is found commonly in largé 
tears or masses, of a dark yellow or reddish-brown colour. This 
gum, which has a transparent appearance, being nearly free from 
cracks or fissures, is said to be readily soluble in water, and to
