S. Cushing Co. - Berwick & Smith Co. TEACHERS' PREFACE IT has been the aim of the compiler to present the subject of hygiene in such a way that it may be of practical everyday use to the large number of pupils who will have no further opportunity for study of the subject. The chapter on Bacteria may be thought unnecessary; but the relations of bacteria not only to disease but to housekeeping, farming, and many other industries are of increasing importance, and the time fast coming when a whole text-book and not a single chapter will be devoted to bacteriology in all schools. It may be thought also that too much space has been devoted to the hygiene of occupation; but the subject is one of vital importance to the nation as well as the individual and it daily becomes more difficult to separate the physical conditions from the social conditions in all questions of hygiene. The writer would suggest the following additional helps to a better understanding of the subjects. CHAPTER I. Lecture with microscopical and blackboard illustrations, by Medical Inspector or other doctor. CHAPTER II. Demonstration of difference in well and badly cooked foods, especially bread, pastry, cereals, and overcooked meats. Show fresh and wilted vegetables, and good and bad meats. If no dietitian is available, the demonstration may be easily done by any teacher. |
