    The epidemic seems to have broken out in September, 1863. The number of cases, however, during that month was not great, but in the next month, October, 1863, they were nearly trebled, and through November and December contirued to rise steadily. Towards the end of January, 1864, they fell somewhat, and then continued nearly stationary through February and March. During April and the early part of May, 1864, the number of cases dwindled considerably. In the end of May, however, there was a sudden rise, and a similar one in the middle of June, but, with these exceptions, the number of fresh cases continued to diminish until August, 1864 presented the same number as the first month of the epidemic, September, 1863. In September, 1864, the number again rose rapidly, being not far short of double that of the preceding month, and this rise was kept up during the next mouth, October, but fell somewhat in the two remain- ing months of 1864. January, 1865, showed a slight increase, followed by a decided fall in February, to a point lower than had been reached since the outbreak of the disease; but this gave way to a steady in- crease, continuing througli March, April, May, and commencement of June. The latter part of June and July produced a very rapid fall to a point lower than had yet occurred; but in August the number rose to nearly the same as in August, 1864. September witnessed a further slight rise, but much less than in the preceding year, while in October and November a slight fall occurred, which increased in December. The commencement of 1866, during the first two months, produced little change, but in the beginning of March arise occurred, which, however, did not continue. April produced a slight decline, which continued during May, after the middle of which month the disease rapidly subsided. June produced few cases, and the whole may be said to have then ceased, as only an occasional stray case oc- curred afterwards. The following table will show the number of admissions; the months being for the sake of convenience divided into four parts each ; the first fifteen days into periods of eight and seven days re- spectively, and the remainder of each month into periods of eight and seven days, or into two periods of eight days each according as there are 30 or 31 days in the month. These period? may be roughly stjled weeks.
