GUMS, RESINS, AND KINOS. 255 
“Grey Gum,” “ Bastard Box,” etc, (For other names and synonyms, 
see ‘‘ Timbers.’’) 
This is the dullest looking kino the author has everseen. Its 
general colour is brown; it can readily be reduced to a fairly fine 
powder between the fingers. It forms a light reddish-brown turbid 
liquid, leaving a muddy-looking residue of a salmon colour, 
evidently composed of finely divided particles of resin, wood, and a 
gelatinous substance. The last portions of soluble matter are 
exceedingly tedious to extract.

N.O., Myrtacez, B-FI., iii., 257. 
“ Bloodwood.” (See also ‘‘ Timbers.”) 
This tree is for the most part sparsely distributed, and then 
on rivers and creeks; also, very few trees exude kino, and then 
only in small quantities. A small sample in the Technological 
Museum has quite freshly exuded. It is in very small fragments, 
with attached bark. It is of a pale ruby colour, and very bright 
looking; colour of powder, dark salmon; it can readily be 
crushed by the fingers. With water it forms a pale orange-brown 
liquid, with a light brown sediment. 
South Australia, New South Wales to Northern Australia. 
a7 Eucalyptus tesselaris, Hook., (Syn. EZ. viminalis, Hook. f.; 
EF, Hookeri, F.v.M.); N.O., Myrtacez, B.FI., iii., 251. 
“ Moreton Bay Ash.” (For other vernacular names, see ‘“‘ Timbers.”’) 
This kino has the property of exuding of a dark brown treacle- 
colour, and soon becoming black without any tint of red. 
According to Mr. Staiger, it has a specific gravity of 1.35, and 
contains 71.7 per cent. of matter soluble in boiling water, and on 
cooling the solution becomes turbid, and deposits catechin. The 
portion insoluble in water is soluble in alcohol, and the residue, 
when treated with ether, leaves a dark coloured brittle mass 
identical with shellac, possessing the same qualities, both 
technically and chemically, and giving a good French-polish of a 
rather darker colour than the usual commercial article. This 
shellac constitutes about one-fifth of the entire gum; it is insoluble
