PROF. F. H. SNOW, UNIVERSITY OF KANSAS. 



The most notable features of the year 1884, as observed at Lawrence, were 

 the low mean temperatures of the spring, summer, and winter months ; the high 

 mean temperature of the autumn months ; the very large rainfall, which came 

 within half an inch of the extraordinary precipitation of the year 1876; the un- 

 usual percentage of cloudiness; the low velocity of the wind; the decided 

 preponderance of south winds over north winds; and the increased percentage of 

 atmospheric humidity. 



Temperature. — Mean temperature of the year, 51.30°,. which is 2.11° 

 below the mean of the sixteen preceding years. The highest temperature was 98**, 

 on July 8; the lowest was 21.5° below zero, on the 5th of January, giving a 

 range for the year of 119.5°. Mean at 7 A. M., 45.69° ; at 2 P. M., 59.40° ; at

 average winter temperature; of the spring, 51.41°, which is 2.41° below the 

 average ; of the summer, 73.05°, which is 3.05° below the average ; of the autumn, 

 56 59°, which is 3.01° above the average. 



The coldest month of the year was January, with mean temperature 20.99° 5 

 the coldest week was January ist to 7th, mean temperature 0.07° below zero; the 

 coldest day was January 5th, mean temperature 12° below zero. The mercury 

 fell below zero fourteen times, of which seven were in January, one in February, 

 and six in December. 



The warmest month was July, with mean temperature 76.93°; the warmest 

 week was July 20th to 26th, mean 79.66° ; the warmest day was July 8th, mean
