Disease In War

[From the New York Timee.J The Bussians will encounter one eneiny on the Lower Danube which the most daring courage and the best organization cannot completely conqtier - that is disease. The flat banks on the Boumaniau side of the great river are overflown in the spring. As the water retires, there is a broad stretch of quagmires and stagnant pools for miles in extent - a proliftc source of malarial fcvers. As the heat increases in the burning summei, these marshy hollows are ñlled with a high, rank grass, so that for miles the eye can see nothing but broad steppes of waving grass, without a tree or a house. These meadows, however, seem equally unhealthy with the more swampy plains of spring, and, owing to the putrescent vegetation and the scarcity of pure water, are a peculiar niduiS for cholera and intestinal diseases. In the campaign of 1828, the Sussians are believed to have lost 80,000 men between the Prnth and the Balkans, of whom much the larger proportion perished from "plague " - which appears to have been a malignant form of typhus, cholera, nnd typhoid or malarial fevers. In 1829, they'lost 60,000 men, mainly from disease, and, out of the wliole army of 100,000 men, the returns showed more than 200,000 cases in hospital, or aii average of two hospital treatinents for each soldier during the year. When the Bussian General tookAdrianople, hehad amere skeleton of an army, and, af ter the peace of Adrianople was rnade, he had but 10,000 to 12,000 men to lead back over the Danube, so reduced had his forces been by sickness. In fact, fever and cholera had already defeated him bef ore the peace, and, had the Sultan but known the real condition of the army, the issue of the war would have been utterly different. The great deflciencies of the Muscovite service are the commissariat and the medical staff, and never were the results of these deflciencies so painfully shown as in the war of 1828-'9. In 1854-'5, the Bussians suffered, but, owing to their more limited operations on the Danube, not to the same extent as in the former campaign. It was in these years that the allies feit the terrible climate of the plains of the Danube and the Dobrudscha. The British and French camps near Varna became abodes of pestiience. In the French movement to the Dobrudscha in pursuit of the Bussians, who had abandoned the siege of Silistria, the march became a track of death. Cholera destl'oyed a forcé before it reached the enemy; and the French had not made many marches before they found that it was all the living could do to take care of the dying and dead. The pursuit soon turned into a retreat before the ghastly enemies of pestilence and fever. Tñe especial causes were said to be the bad water, the wells poisoned by carcasses thrown in by the Bussians, the burning heat of the sun and cold nights, and the miasma from the lately submerged ground. In fact, if the genius of the allied leaders had not transferred bhe war to the comparatively healthy península of the Crimea, the allied expedition to sustain the Ottoman empire would have ended in disaster and disfrace.
