man now knows it all but the Y best scientists now realize we never shall do that on this earth thus we know there are what we must cail natural or absolute units beyond which we on this universe cannot go one of these units Is a velocity of miles per second hie speed of light Is the absolute depth of cold when there Is no heat at all beyond these we cannot go moreover we are not yet wise enough even to know what all the things in our big machine are put for and though they go on working we dont even know what it la they are doing only in 1923 did we find out what that sly fellow insulin was busy over this shows how infinitely mure wonderful than ours roust be the wisdom that directed the making of our bodies and of our world nobody knows what consciousness ness Is we do know it Is not necessary to the life of the body because we go to sleep and become unconscious without the least fear this potato Is alive but if I 1 thought it was conscious I 1 care to eat it we know that the sun attracts the earth and the earth the sun but we dont know why we know this pen will fall down it I 1 let go of it we say of course it will because that Is a law of nature but we dont know why it falls laws dont explain anything they only state facts and leave us little wiser so I 1 must bring these talks to a close leaving lots of things unexplained As you ask me questions I 1 will collect them and we will talk over the answers another time today I 1 want to say one word about defenses the best defense Is prevention far better than cure the wisdom that built up our bodies knew that and already we have spoken of many defenses of the most wonderful we have said little amongst them come first the factories that have no ordinary outlet through a channel that we can see but that like the islands in the pancreas slip their most wonderful secrets right into the blood stream there are four of these chief factories one in the neck called the thyroid man has now found out its messenger lie has called it it has much to do with control of growth and its discovery Is on of the great triumphs of science A child who has for any reason no thyroid Is a stunted dwarf ugly and feeble minded see picture here Is a picture of one taken by doctor oslar two years old and here ts the same three years old after a years feeding on on the other hand some people have too much and would die it doctors take away part of the factory then there are small factories called near thyroids but w dont know what they do though we do know aliey are absolutely necessary the tiny factories in the middle 0 abo floor of the brain ased to b thought to be the home of mans soul it Is called the pituitary body W now know that its secret messenger has a direct control of the pipes and pump and also some influence on growth on the very top of the kidney Is etall another factory its messenger we ure a great deal to contract hie email pipes and to stop bleeding you have heard of it perhaps we call it just adrenalin which only means on ali kidney the big spleen we inow now Is the great filter of the blood itself its cella also oat up dying reds and probably help to mako MIT one see picture of the other kinds of elands there are nearly 00 all built up much on the same principle and in each there are specially trained cells to produce special products needed for some part ot the body and yet all these work together or alie body la really one unit protoplasm like cement actually unites cell to cell ail over body the more complicated a town Is the more dependent one man in it IB on another the doctor on the lawyer the lawyer on the doctor the householder on the carpenter and thecae penter on the householder the mistress on the cook and the cook on the mistress each person does one thing that the others cant do I 1 have found educated men from great who would starve to death where a roving eskimo will make a good living the world can however only really get on by every one doing his part well so remember the world needs you too are not in it to get things but to give things you have been born for some purpose that and that only makes life worth while for it Is so short and however much we get we can carry nothing with us but the record of what we did look at this old robins nest on the window sill only a few days ago we were watching the robins build it with great care then we saw the young robins born in it and today they are already all gone and now we burn the nest which Is only so much rubbish and Is in our way while you and I 1 have time let us try to enjoy the greatest happiness that of helping to make a better world ot all the pictures I 1 know one somehow helps me more than any other there was once a poor doctor but a very earnest fine man he noticed that the lives of people who milked cows with a kind of rash on them were spared when that terrible scourge called smallpox was killing one in ten of the population of the world he loved his little baby boy as much as your father does but he was so splendid a knight that after he had taken every possible precaution he decided to put some of the poisonous composition into the body of his own little boy to find out it it really would save childrens lives the picture Is of him trying that and it did all that he hoped doctor jenner will never be forgotten because directly and indirectly he has probably saved more human lives than any other man who ever lived abraham lincoln david professor pasteur lord lister most of the worlds great men have been exactly like you and me and like sirs wiggs of the cabbage patch they did their bit and so as longfellow tells us we too it we will can each be a hero in the strife so begin by knowlie all you can about and holding absolutely sacred our body the only one in which you an face that great adventure that nan call LIFE B by bell inc |
