Excerpt from Air and Water IN this little book I have attempted to bring before my readers the wonderful changes and actions which are going on around them in our atmosphere, and the even more marvellous work which water is performing in nature. A knowledge of the relations which exist between our health and the air we live m, and of the effects which water and its various impurities have upon our system, is so important, and has so wide a bearing upon the comfort and well-being of the human race, that this knowledge should form an important factor in our National Education. Unfortunately it is only of late years that the true import ance of natural science has been recognized, and it is Often found that amongst the well-educated classes but little is known of the subject, whilst in an ordinary commercial education the time devoted to science is small indeed.
