SANITARY COMMISSION. No. 172. RULES FOR PRESERVING THE HEALTH OF THE SOLDIER. [second edition.] The members of the Sanitary Commission ordered by the President of the United States, and acting under the direc- tion of the Secretary of War, in co-operation Avith the Army Medical Bureau, to secure by all possible means the health and efficiency of our troops noAv in the field, and to prevent unnecessary disease and suffering, do most earnestly and affectionately request their brethren of the volunteer and militia to adopt and carry out the following '' Rules for pre- serving the health of the soldier." They are derived from the highest authority and the largest experience of military and medical men, and it is believed that, if folloAved Avith the intelligence and honesty of purpose Avhich characterize the American soldier, they Avill sa\"e the lives of thousands of brave men who Avould be otherAvise lost to the service of their country. They are addressed alike to officers and privates, inasmuch as the latter are liable to promotion, and upon their officers devolves the responsibility of securing their health, safety,. and comfort. They will be found in no instance to conflict with the "Army Regulations," by Avhich all ranks are governed, and Avith which every good soldier should be familiar. 1. It is absolutely necessary, for the sake of humanity and the efficiency of the Army, that every man laboring •) under any physical infirmity Avhich is liable to unfit him for bearing Avithout injury the fatigues and hardships of a soldier's life in the field, should be promptly discharged from the service by his commanding officer on a surgeon's certificate of disability. (Army Regulations, par. 159-167. and 1134, 1135, 1138.) It is the duty of every good soldier Avho is conscious of any such disease or defect, Avhich may have been overlooked on inspection, to report himself to the surgeon for advice. In case of discharge, means are provided for his prompt payment and conveyance to his home. 2. Every officer and soldier should be carefully vaccinated Avith fresh A*accine matter, unless already marked by small- pox; and, in all cases Avhere there is any doubt as to the success of the operation, it should be repeated at once. "Good vaccine matter Avill be kept on hand by timely requisition on the Surgeon General." (General Regulation?. par. 1105, 1134.) 3. Medical officers are earnestly advised to make them- selves familiar with the "Revised Regulations for the Medical Department of the Army,'' a copy of which should be obtained by application to the Surgeon General. They Avill thus learn the proper modes of securing supplies of medicines, instru- ments, and hospital stores, and rules for official conduct under all circumstances. 4. The articles of food composing the rations issued by the United States Commissary Department have been proved, by sound experience, to be those best calculated for the food of the soldier. The amount alloAved for each man is greater in quantity o than the similar alloAvance for any European soldier. If he understands his duties and manages Avell, any Commissary of Subsistence can save from 15 to 30 per cent, out of the rations furnished by Government, and Avith the money thus saved, fresh \regetables, butter, milk,
