the mean amount of cloud was greater at the time of full 

 moon than of new moon. The observations of mean daily 

 temperature show that the days of full moon were on the 

 average ri9° colder than the days of new moon. He was 

 led to infer that at times of full moon, northerly winds had 

 been more frequent than at the times of new moon ; the 

 observations made at Southport confirmed this view. The 

 numbers obtained also indicated that the frequency of 

 northerly winds under the full moon and last quarter, as 

 compared with that under the new moon and first quarter, 

 has gradually diminished during the seven years (1871-78) 

 of observation. Assuming that the diminution is due to the 

 gradual diminution of solar activity, the ratio might be 

 expected to be a minimum during the year 1878-79. An 

 examination of the Radcliffe observations confirmed his 

 opinion that the moon exercises a noticeable influence on 

 the direction of the wind.

Session 1880-81. — "Ozone and the Rate of Mortality 

 of Southport during the nine years 1872- 1880." From 

 observations made during the period, he found that in four 

 of the five years of low amounts of ozone the zymotic death 

 rate was above the mean, and in the fifth slightly below ; 

 and in the four years of high amounts, the rate was always 

 below the average. During the five years of low amounts 

 of ozone the gross death rate was 12*8 per cent greater than 

 in the four years of high amounts of ozone, the local death 

 rate I0"9 per cent, and the zymotic death rate 92*6 per cent 

 greater. He thinks that the corrected amounts of ozone 

 represent the actual purity of the air at Southport during 

 the nine years, and that variations in the actual amount 

 exercise a very sensible influence upon the state of public 

 health.
