THE CHOLERA.
The cholera, which broke out at the close of 1848, slumbered during the winter and spring, 1849, and then ravaged the country, continued to afflict, more or less, during this year also. The mitigation and removal of the disease during the year enabled medical and scientific men to give more calm and undisturbed investigation as to its phenomena. Some of the laws which characterized its advance, prevalence, and removal, were discovered and brought before the public; but the cause or source of the pestilence still remained a mystery, and no specific treatment was discovered. It was remarked that it appeared generally in the same districts, towns, streets, houses, and some persons affirmed, even apartments, which had entered in the year 1832.
