22 J. D. Everett on Reducing Observations of Temperature. 
torily tested, as the interpolations (in defect of observations) at 
this station are numerous during the years 1857-8. In the year 
56, which is entirely free from interpolation, Yester appears 
to have been 16 days earlier than Thurston, and 11 earlier than 
East Linton, a remarkable difference, considering that all three 
places are in the same county (Hast Lothian). Comparing one 
year with another, it appears that the seasons were latest in 1857, 
being fully a week later than in 1856, and at some places about 
a fortnight later than in 1858. At Thurston the difference be- 
tween the last two years amounts to nearly 21 days, All the 
inferences as to dates contained in this paragraph, are derived 
from mere inspection of the values of HE, bearing in mind that a 
degree nearly corresponds to a day, and that the phases are ear- 
ier in proportion as EH, is greater. 
s an instance of the convenience afforded by the present 
method, for comparing the climates of different countries, I sub- 
join the values of A,, A, and E, for Edinburgh, and for Albion 
Mines, N. S., the former derived from the monthly means of the 
late Mr. Adie’s observations, embracing a period of 40 years, for 
which I am indebted to a paper by Principal J. D. Forbes, as 
epitomised in the Ed. New Phil. Journal for July, 1860, the lat- 
ter from 11 years observations by Mr. Henry Poole, Manager of 
the mines. The monthly means themselves are—

from which are derived the following values of mean tempera- 
ture, amplitude, and epoch: 
Edinburgh, Ay—469 A,==108 E,=83° 27’ 
Albion Mines, Ari A ,==28'°0 E,=78° 13! 
. Hence, cleared of technicalities, the relation between the two 
climates may be expressed by saying that the village of Albion 
Mines is on the average of the year about 5° colder than Hdin- 
burgh, that its range is rather more than double, and that its 
seasons are on the average 5 days later. No such definite in-
