consolidate scientific work and increase its efficiency by 

 the creation of a controlling Science Department, which 

 would administer the different scientific establishments 

 now under separate departmental control. 



The results which would shortly be obtained by the 

 labours of such an administrative body, would also impress 

 the public with the value of properly directed scientific 

 work, and lead to a demand for better and more accessible 

 instruction in science, and would assist the material pros- 

 perity of the country as nothing else could. For, after all, 

 however much legislation may favour or hinder commerce 

 and industry, the pre-eminence of a country in this regard 

 depends finally upon the energy and the intelligence of its 

 people, and it is in the facility given to scientific research 

 and the diffusion of scientific knowledge that the real 

 foundation of the future prosperity of a country depends.

This paper is the first of a series which will deal princi- 

 pally with the tannins and allied substances occurring in 

 the kinos of the Eucalypts. The difficulties experienced 

 in dealing with such a diverse group of substances as 

 Eucalyptus exudations, were considerably simplified by the 

 researches on the essential oils of the genus, and it is now 

 felt that a systematic order and natural arrangement 

 governs Eucalyptus kinos, similar to that previously shown
