Weather of 1911 in Relation to Health. 205 



rainfall 2.39 inches, and the rainy days 11. The deaths were 62, 

 the rate being 13.290 per 1000. The average death-rate was 

 11.493, and the expected deaths 54. Circulatory diseases con- 

 tinued to yield the heaviest mortality, but the rate from this 

 cause was the fourth lowest of the year. The cancer mortality 

 rate was very slightly above that for August. The figure for 

 phthisis (1.072) was slightly below that for the year (1.110). 

 Pneumonia showed an increase on August, but remained low, and 

 bronchitis re-appeared in the list of causes of death. The cases 

 of scarlet fever were eight, and of diphtheria three. 



October. — From the 1st to the 19th the weather was anti- 

 cyclonic in character with a prevalence of winds from easterly 

 points, a high barometer, low rainfall, and rather low mean 

 temperature. With the latter date the long-continued drought of 

 1911 came to an end after lasting for about four months. From 

 then to the 31st there were frequent wind and rain storms. The 

 average of the barometric readings was 29.597 inches, the mean 

 temperature 45.9 deg. F., the humidity 86 per cent., the rainfall 

 4.09 inches, and the rainy days 11. The total deaths were 64, 

 giving a rate of 13.275 per 1000, practically equal to the average 

 rate 13.243, so that the expected deaths tallied exactly with the 

 actual number (64). The phthisis mortality was at its maximum 

 (1.659) as in January. It was the principal contributor to the 

 death-rate, being in excess of the circulatory disease mortality. 

 After these came cancer and cerebral hsemorrhage. Pneumonia 

 and bronchitis continued low, as did also diarrhoeal and digestive 

 diseases. Cases of scarlet fever and diphtheria began to increase, 

 there being sixteen of the former and twelve of the latter. 



November. — The cyclonic conditions of the latter end of 

 October continued until the 19th of November, after which until 

 the end the weather was more favourable, but over the whole 

 month the barometer was low, the rainfall high, the mean tem- 

 perature about normal. The prevailing winds during the first 

 part were from westerly points, during the latter from northerly 

 and easterly. The average of the barometric readings was 29.303 

 inches, the mean temperature 40.7 deg. F., the humidity 88 

 per cent., the rainfall 5.98 inches, and the rainy days 20. The 

 deaths were 70, giving a rate of 15.005 per 1000, which is very 

 slightly in excess of the average, 14.903, so that the actual 

 number of deaths is one above the expected, 69. The mortalities
