But how is it to be done? may well be asked. In the hurry and confusion of a war, and amidst the pressure of hundreds of new cases in a day, what can the surgeons of the hospital be expected to do for science, or even for the improvement of medical and surgical practice?--The answer is seen in the new arrangements in England, where a statistical branch has been established in the Army Medical Department. Of course, no one but the practising surgeon or physician can furnish the pathological facts in each individual case; but this is what every active and earnest practitioner does always and everywhere, when he sees reason for it. His note-book or hospital-journal provides that raw material which the statistical department is to arrange and utilize. The result will be that a flood of light will be cast on matters affecting the health and life of soldiers and other men, in regard to which we might have gone on groping for centuries among the confusion of regimental records, without getting what we wanted. As to the method of proceeding, I may have something to say farther on. Meantime, we must turn to the primary object of the institution of the Military Hospital,--the cure of the wounded and sick of the army. In the case of active war, foreign or civil, the General Hospital is usually an extemporized establishment, the building a makeshift, and the arrangements such as the building will admit. In Spain, the British obtained any houses they could get; and the soldiers were sometimes crowded into half a dozen of them in one town. In the last war, the great buildings at Scutari were engaged three months before they were wanted for extensive use; so that there was plenty of time for making them clean, airy, warm, and commodious, and for storing them with all conveniences. This was not done; and the failure and its consequences afford a lesson by which every people engaged in war should profit. A mere outline of what was not done at Scutari may be an indication of what should be done with all convenient speed elsewhere.
