METEOROLOGICAL NOTES DURING THE YEAR 1900. 205 



flower beds in the parks, and the effect was bright and pleasing. 

 Dahlias and chrysanthemums were in full bloom by the middle 

 of the month, and many deciduous trees rapidly became divested 

 of their leaves, especially elms, limes, and sycamores. 



October. — For the first fortnight the weather was very rainy 

 and unsettled, with, as a rule, fine dry forenoons, which usually 

 gave way in the afternoons to rain or hail. The temperature 

 during this period was high considering the season, but on the 

 15th the atmosphere became much coMer, and for two days the 

 weather was bright and frosty, with a keen snell wind, which 

 suggested the approach of winter. On the 17th a sudden change 

 again took place in the atmospheric conditions, when the bar- 

 ometer fell sharply, and heavy rain came down. During the 

 forenoon of this day a dense blackness overspread the city. 

 Throughout the later part of the month the weather was brighter, 

 though there were few dry days. 



The pressure of the atmosphere as shown by the barometer was 

 moderate and comparatively steady till the 17th, when it rose 

 from 29*40 inches to 30-00 inches on the 19th, and for five days 

 the readings were above 30-00 inches. On the 24th the pressure 

 decreased, and on the 26th the reading was 29*00 inches. 



For the month the rainfall amounted to 5*05 inches, and there 

 were only ten days on which rain was not recorded. 



Frost to the extent of 5° was registered on one morning, and 

 on one other occasion only did the thermometer fall to freezing 

 point (32°). The average maximum temperature was 51° and 

 the average minimum 40°, the maximum being 3° lower and the 

 minimum the same as in the corresponding month of last year. 



The sharp touch of frost experienced on the 16 th was sufficient 

 to bring to a elose for the season most of the outside flowers, 

 Chrysanthemums alone withstanding the cold, and at the end of 

 the month were still giving a little brightness to the flower beds. 

 The grass was also green and fresh, though most of the deciduous 

 trees had divested themselves of foliage. 



November. — This was a month of mild and wet weather. For 

 the first 17 days only two days were dry, and the amount of 

 rain which had fallen during that time measured over 5 inches
