And in five of the eight years in which there are exceptions to the (assumed) 
rule of a higher temperature preceding @, exceptions are also found at the 
period of O. 
And so with the quarters :— 
a rise in nineteen years 
iod of 1 > 
At the period oF « there was 4 4 fall in thirteen years 
\ out oftwenty-one. 
Only two exceptions occurred at ), and in both cases they are found in the 
same years at ¢. 
2. Winter lunations to all appearance exercising a considerable influence 
upon the mean temperature of the two days at the period of ), inquiry was 
next extended to individual months.. The results evidence the same marks 
of system that have been already observed in the yearly means. 
In the months of October, November, December, and January, the pro- 
portion in which a rise or fall occurred from the third day before to the 
second day after the syzygies and quarters, during the same twenty-one 
years, was as follows :— 
@ a rise in 13 out of 21. 
O a fall in 15 out of 22. 
@ a fall in 16 out of 23.

In the summer months a rise prevailed in the proportion of about 3 : 2, 
* at all the periods, excepting in May, at the time of ), when it was as 4: 1. 
At the period of (, there occurred in the same 2] years the following 
remarkable alternations of temperature :— 
In March,.. a rise in 12 out of 21. 
In April,.. a fall in 13 out of 21. 
In May,.. arise in 13 out of 21. 
In June,.. a fall in 13 out of 21. 
In July,.. arise in 13 out of 21. : 
In August, a fall in 13 out of 21. } 
Strong indications of similar reciprocity were traceable in separate lu- 
nations and at different periods of the same lunations. 
3. Further evidence of system was next obtained from the highest and 
lowest mean temperatures of each month. These were found in a tabular
