A twelve page mimeographed pamphlet has been prepared on DDT by the Research Department of the Hospital Bureau of Standards and Supplies. This pamphlet is bound and perforated for filing. The report has been checked by the Department of Agriculture for accuracy. Discussion is brief and concise and is pointed toward the practical application of insecticides containing DDT in hospitals. The information in this report will also be of value to superintendents of other types of institutions, homes and office buildings. Nonmember hospitals can purchase copies of the pamphlet. Preparation, effectiveness, usable forms, precautions, government control, history, summary and selected bibliography are the important divisions of the subject matter.
