I hope I have succeededin making that clear. It is a mixture of gases. Inaddition to these gases there is water vapour and anumber of impurities. It was my fortune to deliver alecture here about a fortnight ago dealing with theseimpurities, and to speak of dust in relation to disease,therefore, I need not deal with that aspect of the questionnow. I shall now attempt to show you what we do to theair and what it does to us. I have shown you that wegreatly increase the quantity of carbonic acid gas in anyspace, and that that would go on increasing in the airuntil it became intolerable but for plant life. What isthe explanation of the fact that we take oxygen out ofthe air, and put back carbonic acid gas? Now, that isa question I will endeavour to answer by means of thelantern slides. But perhaps I may supplement what Ihave said by a very simple experiment. Fresh air issplendid. Air breath
