260 Weather of 1910 in Relation to Health. 



there was an excess of winds from between north and east. The 

 deaths were 51, and the rate per 1000, 11.224. Circulatory 

 disease mortahty was somewhat high, but the rates from other 

 causes comparatively low, the highest after circulatory being 

 pneumonia, with .88 per 1000. The average total death-rate of 

 the month being 11.729, the " expected " deaths were 53, or two 

 more than the actual number. Diphtheria became rather preva- 

 lent, and the prevalence was no doubt influenced by the period 

 of drought following the excessive rains of August and increasing 

 the activity of the causal bacilli. 



October was a month of comparatively quiet and mild 

 weather. The barometer was fairly high until the end, when it 

 fell rapidly. The mean temperature was high and the rainfall 

 low. The mean barometric pressure was 29.731 inches; the 

 mean temperature, 48.9 deg. F. ; the mean daily range, 12.0 

 deg. F. ; the humidity, 86 per cent.; the average rainfall, 3.14 

 inches. The rainy days were 10, and there was an excess of 

 winds from easterly points. The total deaths were 54, and the 

 rate per 1000', 11.499. There was a drop in the circulatory 

 mortality from September, but the mortalities from pneumonia, 

 malignant diseases, and phthisis were relatively high. The aver- 

 age total death-rate during the previous decade being 13.40i7, 

 the "expected " deaths were 63, or nine more than the actual 

 number. Diphtheria and scarlet fever were both fairly pre\'alent, 

 but less so than in September. 



November showed very disturbed atmospheric conditions, 

 was cold, wet, and stormy, with a low mean temperature and 

 winds chiefly from northerly and westerly points. The mean 

 barometric pressure was 29.271 inches; the mean temperature, 

 35.0 deg. F. ; the mean daily range, 12.8 deg. F. ; the humidity, 

 88 per cent. ; and the rainfall, 4.32 inches. The number of 

 'rainy days was 15. The total deaths were 57, and the rate 

 12.544. The mortality from circulatory diseases rose consider- 

 ably above that for October. Malignant disease mortality was 

 also high. The rates from pneumonia and other respiratory 

 diseases were low. That from phthisis was the lowest for the 

 year, but from other tubercular diseases it was fairly high. The 

 average total death-rate being 15.108, the "expected" deaths 

 were 69, or twelve more than the actual number. Scarlet fever 

 was again prevalent.
