until it has been taught how properly to use its limbs, and how 

 to exercise all its muscles both in the water and out of it." 



In these days, when the passing of examinations and the 

 gaining of scholarships is made the one desirable attainment 

 in school hfe for boys and girls alike, it is no uncommon 

 occurrence for the successful candidate lo leave school in a 

 state of mental and ])hysical collapse. The reason of this is 

 not far to seek. The brain has been unduly taxed, while the 

 bodily functions have been almost, if not entirely, neglected ; 

 every kind of healthy active exercise has been curtailed or 

 altogether suspended, and physical education has formed no 

 part of the prescribed course. If the exercise of the brain be 

 excessive and beyond the point where the nutrition is equal 

 to the waste, it will suffer in the same way and to the same 

 extent as the other organs of the body. 



May we not hope that the discussion of physical education 

 at this meeting of the Australasian Science Association may 

 lead to its recognition as an important part of our educational 

 system and further its ado])tion in our public and private 

 schools. 



Education in its fullest and widest sense means the develop- 

 ing of the entire physical, intellectual, and spiritual capacities 

 of the pupil. 



Systematic exercise alone ensures the timely and har- 

 monious growth which results in that highest physical beauty, 

 symmetry of form ; but systematic exercise conduces no less 

 to the increased capacity of brain power, by furnishing a fresh 

 supply of pure blood, and relieving the nervous strain brought 

 about by continuous mental effort. 



7.— AN INQUIRY INTO THE ADVANTAGES OF THE 

 DOWNWARD SYSTEM OF VENTILATION. 



By S. HURST SEAGER, A.R.I.B.A., President of the Sydney Architec- 

 tural Association. 



{^Abstract.'] 



After referring to various systems of ventilation in vogne, 

 the aathor went on to say : — 



Now, I would ask you to note, that according to the 

 accepted theory of the action of the upward system of venti- 

 lation, there must be a dowmoard movement of the fresh air 

 before its extraction, if the system is to be in any degree
