The purpose of this book is accordingly to put the accepted facts in such a form that they will the more readily become matters of common knowledge. By an appeal to those who can read the newspapers intelligently and remember a little of their high-school physiology, an immense body of interested citizens can be added to the forces of a modern campaign against the third great plague. For such an awakening of public opinion and such a movement for wider coöperation, the times are ready.
