PRESIDENTIAL ADDRESS. 
At first he turned his attention to geology and conchology, 
publishing, in 1866, an appendix to 8. P. Woodwards 
-““Manual of Mollusca,” and, in 1871, a ‘‘ Rudimentary 
Treatise on Geology.” In 1876 he published, in conjunc- 
tion with Mr. J. F. Blake, a book on the “ Lias of York- 
shire.” On his appointment to the Chair in the Adelaide 
University, he at once, with great zeal, threw himself into 
the study of the geology and paleontology of South 
Australia, making extensive travels over the country. He ~ 
now added botany to his other aceomplishments, and pub- 
lished a “ Handbook to the Flora of South Australia.”’ 
He was President of Section D of this Association at its 
first meeting in Sydney in 1887, taking for the subject of 
his address the geographical distribution of the plants of 
Australia and its relation to the geological history of the 
continent. When we met at Adelaide, in 1893, he was 
chosen President, and gave us a very comp'ete account of 
the progress of geological discovery in Australia. And, at 
the Melbourne meeting, in 1900, as President of Section C. 
he made a vigorous attack on the doctrine of homotaxy. 
THE ASSOCIATION. 
During the ten years which have passed since our previous 
meeting in Hobart, the Association has grown greatly in 
strength and influence through the good work it has done 
for the advancement of science in the Southern Hemisphere , 
and I think that our Permanent Secretary, who was the 
founder of the Association, ought to be proud of his work. 
and very hopeful for the future. 
The ten Sections into which the Association is divided 
include all branches of Science—physical, physiological, and 
mental—and we try to advance both pure and applied 
science. For scientific men may be divided into two 
groups—the investigators of theory, and the reducers of 
theory to practice. The workers in applied science have for 
their aim the material advancement of the human race. 
Not only do they bring health to the sick, and an increase of 
comfort to us all, but they help to make every-day work 
more interesting to the intelligent, and thus lift the toiler 
on to a higher level. Also, by increasing the wealth of the 
world, they give to some men sufficient leisure to pursue 
pure science or philosophy undisturbed. 
On the other hand, the student of pure science—whether 
he be an astronomer engaged in studying the movements 
and composition of the starry host,or whether he be a 
humble entomologist—he, also, has a high object to attain
