The report of the Surgeon-General of the Army, which has just been received, contains some interesting details. Notwithstanding the fact that the active service of the Army is in the tropical regions, which are generally supposed to be more trying in a sanitary point of view than temperate ones, its general health for the year 1900 has been excellent. The higher rates of mortality were among the volunteers in the Philippines, thus showing that this type of servicehas its disadvantages from a sanitary as well as from other points of view. In Cuba the mortality ratio for 1900 was little more than one-half that of the preceding year and, but for the occurrence of yellow fever, would have been still further reduced. There were 144 cases of this disease, of which 32 were fatal. In Porto Rico the death-ratep was the lowest, 5.05 per 1000, ever recorded in the army.
