![frequently in autumn, least frequently in spring; whilst in the latter season rheumatic affections are most general. The mortality from small-pox is greatest during winter and spring. Out of 182 outbreaks of cerebro-spinal menengitis in Europe, enumerated by Simon, 24 occurred in October and November, 46 in December and January, 48 in February and March, 30 in April and May, 24 in June and July, and 10 in August and September. Asiatic cholera is essentially a summer disease, though an occasional out- break of it in winter has taken place. The mortality from cholera makes its highest point in these countries in August or September. Out of 29,308 deaths from diarrhoea recorded during sixteen years in London, two-fifths occurred during the thirtieth to the thirty-seventh week of the year inclusive. The greatest mortality was in the thirty-second or thirty-third, the least in the fourteenth week. The percentage of deaths from diarrhoea was 42 in summer, 40 in autumn, 10 in winter, 8 in spring. Inwinter thoracic complaints—bronchitis, pneumonia, phthisis, &c. —are most prevalent, and are the chief factors in producing morta- lity. Dr. E. Smith has analysed the vital statistics of London for the period 1850 to 1854 (non-epidemic years), inclusive, and has ascer- tained the amount of mortality occasioned by each of the most important diseases in each quarter of those years. From his inquiries he has constructed the following interesting table :— Table showing the Excess or Defect in the Prevalence of certain Diseases at each Season of the Year from the Amodnt which would have occurred had the mortality been equally distri- BUTED through THE Year.
