XoTK. — Tbo luontlily lueana do not includo Sunday obsurvatious. Tho daily means, cxceptiu;; tliose 

 that relate to the wind, are derived from six observations daily, namol.y, at 6 a. ni., 8 a. ni., 1! p. lu., 4 j). ni., 

 10 p. m., and midiiigbt. Tho means and resultants of the wind are from hourly observations.

 Possible to see aurora on 18 nights; impossible on 12 nights.

Hail of l.irgo .size and to a considerable amount fell in tho storm of the 19th. 



Solar raiul)ow on 12th. Lunar rainbow on 19th at 8 p. m. 



From these tables it is manifest that tliere was no extraordinary state 

 nor extreme changes in the weather during the whole of the month, the 

 last days of which witnessed the outbreak. The mean temperature was 

 in excess of that of September, 1871, but considerably below that of 

 this month in many previous years. Both maximum and minimum 

 temjierature are slightly above those of 1871, but the maximum is less, 

 and the minimum more than those of several previous non-influenza 

 years. The monthly range of temperature was nearly 2° less than that 

 of 1871, and 11° under that of 1854, which was not an influenza year. 

 It may be added that the greatest daily range for September, 1872, was 

 27°5, while for September, 1871, it was 31°5. The greatest velocity 

 of the wind in September, 1872, was 2.21 miles on the 13th, wind in the 

 northwest, and temperature Gl°l. The highest velocity in September, 

 1871, was 26^0 miles on tho 17th, with wind northwest by north, and 

 temperature 52'39. Appended are the tables for October, 1871 and 1872, 

 which show that month to have been no more remarkable through the 

 period of the greatest prevalence of the influenza.
