directors avail themselves of the instructions contained in these volumes. There are several other works on the Crimean War, by surgeons and other officers, written mainly to give a knowledge of the general facts of those campaigns, but all incidentally corroborating and explaining the statements in the Government Reports, in respect to the health and sufferings of the British and French armies. In this view, Dr. Bryce's book, "England and France before Sebastopol," and M. Baudens's and M. Scrive's medical works in French, are worthy of great attention and confidence. The most important and valuable work, in this connection, is the Report of the British Commission appointed in May, 1854, "to inquire into the regulations affecting the sanitary condition of the British army, the organization of the military hospitals, and the treatment of the sick and wounded." This commission included some of the ablest and most learned physicians and surgeons in the civil and military service, some of the most accomplished statisticians, sanitarians, army-officers, and statesmen in the United Kingdom. They were authorized to inquire into the habits and duties, the moral and sanitary condition of the army, the amount and kinds of sickness, the causes and frequency of death, and the means of improvement. This commission sat for a long time in London. They called before them fifty-three witnesses, among whom were Sir Benjamin Brodie, the leading surgeon of England, Dr. Andrew Smith, Director-General of the Medical Department of the Army, Thomas Alexander, Inspector-General of Hospitals, Major-General Airey, Quartermaster-General, Dr. John Sutherland, late Crimean Commissioner, and one of the leading authorities of Great Britain in all sanitary matters, Dr. William Fair, the chief and master-spirit of the Registry-Office, and the highest authority in vital statistics, Colonel Sir Alexander Tulloch, author of the elaborate and valuable reports on the mortality in the British army, Francis G. P. Neison, author of "Contributions to Vital Statistics," Miss Nightingale, and others, surgeons, officers, purveyors, engineers, soldiers, and medical and sanitary scholars.
