BOOKS AND REPORTS 1335ship will wear. Do your sanitary inspectors start out on their public business clad in dungarees? Do your public health nurses wear slacks and sweaters on duty? Do these other messages, your annual reports, go about their illuminating task dressed in drab covers from which they peer suspiciously in bleary print, their eyes surrounded by antiquated, boxed borders? If they do, then Brother, you very badly need to ponder over the last pages of this HOW-TO-DO-IT! There you will find what the well dressed report should wear.

Summary The results of this investigation show that by feeding five table‐spoonfuls weekly of vitamin‐rich cod liver oil to average industrial employees the number of severe colds can be materially reduced, the number of persons having no colds may be increased, and the amount of time lost from work may be very significantly decreased. Obviously cod liver oil should not be looked upon as a panacea but the results of this investigation show that lost time due to colds and similar troubles may be materially reduced by the regular consumption of cod liver oil and thus the annoyance and expense which lost time causes the employer and the employee can be significantly reduced.
