of E. Uucoxylon and E. viminalis received from M. Ch. Naudin 

 of the Villa Thuret, Antibes, France, where is a celebrated planta- 

 tion of many species of Eucalyptus. I will refer to E. viminalis 

 under that heading, and would observe that apart from the 

 evidence yielded by the experiments on the kinos themselves, the 

 leucoxylon trees must have been raised from seed of trees 

 indigenous to Victoria or South Australia. 

 Following is their analysis : —

 The constituent in the above analysis worth noting is the gum. 

 Obviously the conditions under which these trees grow favour the 

 development of gum, as this substance, though always carefully 

 looked for, is absent in turbid kinos obtained from Australian 

 grown trees. In several species I have believed that I have found 

 gum (never much more than a barely weighable quantity, however), 

 but on more thorough examination the substance is found not to 

 be precipitable by alcohol. Care must be taken to remove all 

 catechins before the alcohol is added.

General appearance, friability, and colour of powder normal. 

 It does not entirely dissolve in cold water; it forms a dirty brown 

 liquid, which does not settle readily. It does not entirely 

 dissolve in alcohol, the supernatant liquid is clear and bright, but 

 when agitated it forms a very turbid liquid of a dirty brown 

 colour.
