among the aboriginal population in the Australian tropics, 

 and these diseases, in many cases, became transplanted to 

 the white males, who live mostly unmarried in that part 

 of the country. If the Asiatic aliens are permitted, as up 

 to the present, to live in their own highly unsanitary ways, 

 and to have free intercourse with the other elements, it is 

 certain : that in the near future tropical Australia will 

 become much more dangerous to white settlement than 

 is the case now. 



Many more or less well informed authors speak and write 

 about the deterioration of the white population in the 

 tropical and subtropical parts of Australia by the influence 

 of the climate. But there are many other influences besides 

 the climate which are to be held responsible, if any deterior- 

 ation should be proved in reality. 



The houses and also the hotels are generally badly fitted 

 for the climatic conditions, especially the corrugated iron 

 humpies, which are the most inappropriate and the most 

 numerous of all kinds of architecture. The general diet 

 can hardly be called good for the exigiencies of the climate. 

 Meat of one and the same kind is the chief nourishment, 

 but is consumed in a state which bailies description, vege- 

 tables and fruit arerarae aves on the table, especially out- 

 side the larger towns. This kind of diet is certainly very 

 unhealthy, especially for women and children. 



The water used for all domestic purposes, and even for 

 drinking is very often bad, sometimes even a filthy mud 

 from waterholes, on whose borders carcasses of animals 

 are scattered, and it is really a wonder that epidemics of 

 great virulence do not decimate the population living under 

 such conditions. 



I should think that taking these accessory facts into 

 proper consideration, our evaluation of the climate itself 

 would be much more favourable. If the germs giving origin
