ANNIVERSARY ADDRESS. 35 
and the chronograph has been applied to the study with great 
success. A great deal of new theory has found its way to exact 
expression on paper, and a successful experimental machine has 
been constructed as an expression of the theory. Many of the 
results so far obtained might have been embodied in papers, but 
the Professor prefers to delay publication until the investigations 
are complete. 
Owing to enlargements and alterations, the Engineering 
Laboratory at the University could not be used, and Professor 
Warren has devoted available time to working out and preparing 
for press, the results of previous experiments on Australian timbers 
and the results will be published immediately. The new machinery 
is being got ready for testing timbers, building stones, cements, 
concrete, &c. The Professor expresses in a paper read to the 
Architectural Association, the results of some experiments on 
“Tron and Steel as applied to Building Construction,” and to the 
Sanitary Section of the Australasian Association at Hobart, he 
read a paper on “‘Sanitary Engineering as applied to Drainage of 
Cities and Towns and the Disposal of Sewage.” He is now en- 
gaged in writing a text-book on “Iron, Steel, and Timber, as 
applied to Engineering Construction,” and has sent to the Institu- 
tion of Civil Engineers, London, a paper on “ Australian Timbers.” 
The Professor of Anatomy in our University, Professor Wilson, 
is, I believe, at present engaged in investigating the myology of 
the new and remarkable mammal, Notoryctes typhlops, recently 
found in South Australia. It isa gratifying indication of our 
scientific progress, that such work should now be carried out in 
Australia and in our Medical School, instead of being, asa matter 
of course, entrusted to English or foreign scientific observers. 
The Professor of Geology in our University, Professor Edge- 
worth David, in his address to Section C. of the Australasian 
Association for the Advancement of Science meeting at Hobart, 
contributed to the Geology of Australia the results of his 
investigation of the evidences of volcanic action in Eastern 
Australia and Tasmania, with special reference to the relation of
