44 SCIENCE AND THE STATE, ETC. 



harmless. It is, no donbfc, owing to this exaggerated idea of 

 infection that there have been such extreme proposals as the 

 New Zealand Act excluding tubercular iia migrants. It is 

 probably due to the same cause that there is some prejudice in 

 Queensland against the building of sanatoria for consumptives. 

 There is not a shadow of foundation for the theory that there 

 is danger to the inhabitants of a township if a sanatorium ia 

 erected in the neighbourhood. I trust there will be no opposi- 

 tion to erecting sanatoria for the poor and for paying patients. 

 Bright sunshine, invigorating air, and cheerful surroundings, 

 are conditions which compensate in some measure for separa- 

 tion from family and friends, alleviate the sufferings, and give 

 hope in many cases of permanent recovery. 



CONCLUSION. 



In the remarks I have made to-night, I have touched upon 

 many controversial points, and I have endeavoured to indicate 

 the lines upon which further research is required. I trust that 

 those engaged in scientific inquiries in Queensland will help to 

 throw light on these points. The report of the new Boyal Com- 

 mission now sitting in London will be awaited with interest, but 

 in the meantime there is no uncertainty as to the course to be 

 adopted by those responsible for the public health. Whatever 

 the result of that inquiry may be as regards the relation of 

 bovine to human tuberculosis, we know that there are many 

 factors in the production of the disease. 



The removal of insanitary conditions by the co-operation 

 of the public with sanitary officials, will secure for Brisbane 

 the enviable position of being conspicuous among all the great 

 cities of the Commonwealth, on account of its low death rate 

 and practical immunity from all epidemic diseases.
