and the provinces. We hope to establish a system similar to 

 that existing in Canada, which makes it possible for a really 

 clever lad, whatever his posi';ion may be, to pass from an 

 elementary school step by step to a university career, and thus 

 attain the highest possible training in any branch of learning, 

 for which he may have shown a special aptitude. 1 feel con- 

 vinced that Queensland will not be behind other States of the 

 Commonwealth and other colonies of the Empire, and that if 

 the university building is commenced, those who have made 

 fortunes in mining and commerce, will follow the example of 

 patriotic Canadians and Americans. With the aid of private 

 munificence and the support of tbe State the Brisbane Uni- 

 versity would become a seat of learning worthy not only of 

 Queensland but of the whole Commonwealth. 



RESEARCH MUST J3E CONTINUOUS. 

 With such a University we need no longer fear the 

 fluctuations in the finances of the State. Scientific researches 

 would continue to be prosecuted within the walls of the Uni- 

 versity, and continuity in research is essential. Science is 

 always extending her frontiers, and scientific work which is 

 stopped in any one direction, is like a mine which is tem- 

 porarily closed down, except that a vein which was being fol- 

 lowed by the prospector in science, may be altogether missed 

 by others and his work be lost to the world. As an instance of 

 the necessity for continuous work and the intricacy of scientific 

 problems, and the need for modifying accepted opinions in the 

 light of new discoveries, I propose to draw your attention to 

 the subject of tuberculosis in relation to the public health. 



HUMAN AND BOVINE TUBERCULOSIS. 

 I was asked to address you to-night more particularly upon 

 some subject attracting attention in England. When I left 

 there was no topic of conversation which was more fully dis- 

 cussed in scientific circles that the relation between human and 

 bovine tuberculosis, and the origin of human consumption. 

 This subject was brought to the front last summer, at the 

 International Congress of Tuberculosis, by the well-known dis- 

 coverer of the tubercle bacillus. Dr. Robert Koch ; and it is 

 of so much importance that the Government has appointed 

 another Royal Commission to re-investigate it. Up to the 

 time of Dr. Koch's discovery of the tubercle bacillus, in 1882, 

 it was a difficult matter to give an exact and comprehensive 

 definition of tuberculosis. Dr. Koch's discovery simplified the 

 teaching of pathology. He pointed out that whatever might
