METEOROLOGICAL RECORD AT CHAPEL HILL 

 FOR THE YEAR 188-5. 



F. P. VENABLE. 



The following record is a continuatioQ of that published in pre- 

 vious Journals of the Society, (I, p. 35, II p. 50), the observations 

 being taken under nearly the same conditions of location, instru- 

 ments, &c., as during the years 1880-1884. Some of the facts pre- 

 sented by the tables may be briefly pointed out and discussed: 



TEMPERATURE, 



The mean annual temperature is 57.87° as compared with 59 77^ 

 for the preceding Ave years. It is 1.55° below the average for twen- 

 ty-one years. The average temperature for the seasons, is Spring 

 56.21°, Summer 77 31°, Autumn 58,65°, Winter 39.28°. For the pre- 

 vious five years these averages were 58 35°, 77. 25°, 61.08'^, 42.39% re- 

 spectively. This shows a summer warmer than the average and the 

 remaining seasons some two degrees below the average. July, the 

 warmest month, had a mean temperature of 79.64'^, about one de- 

 gree above the average. The warmest day of the year was July 

 9th, with a mean temperature of 86.25". The maximum observed 

 was 100*^ on July 9th also. These are to be compared with 90 7° on 

 July 12th, 1880, and 102 on July 22nd, 1883. The coldest month 

 was February, 36.04. This is the coldest monthly mean in six years 

 and is nearly 11 below the average for February. The coldest day 

 was February 12th, with a daily mean of 17.50°. For January 6th, 

 1884, the mean was 10.50\ On February 11th the thermometer 

 reached 9\ On December 30th, 1880, it registered -2 . The obser- 

 vations would show then a generally cold year with a hot summer, 

 yet one in which no great extremes of temperature were expe- 

 rienced. 



HUMIDITY. 



The annual mean is 70.60, a little below the average. October 

 was the month of greatest humidity and April the least. The mean 

 saturation for Autumn is lower than usual, for the remaining sea- 

 sons higher. 



RAINFALL. 



The total rainfall, 46.51, inches is five inches above the average, 

 41.64. The heaviest rainfall was during September, the total
