at Swainswick 24.743 inches. Thus there is an excess of rain at 
Oakwood, compared with Swainswick, amounting on an average 
to 3.873 inches, but varying in different years from 1.20 inches to as 
much as 7.285 inches; the greatest excess appearing in those 
years, in which the total quantity of rain is the largest. And so 
we have here another instance of considerable difference of rain- 
fall in two places, only a few miles apart, clearly independent of 
height above the sea. Probably, in the present case, the increased 
fall at Oakwood above Swainswick is traceable, at least in part, to 
the woods in the immediate neighbourhood. 
Observations on Lansdown.—The different parts of Bath itself 
being at very different elevations, I always thought it would be 
desirable to compare the meteorological conditions of the lower 
parts of the town near the river with those of the highest 
inhabited parts of Lansdown, these conditions being determined 
by contemporaneous observations at the two places.—A Register 
was formerly kept at Ensleigh (the height of which above the sea 
is 740 feet), by the late Charles Weston, Esq., the well-known 
astronomer ; but for some years before his death the register had 
been discontinued. _There are three years, however, or rather 33 
months, commencing with July, 1865, and ending with June, 
1868 (the observations for April, 1866, and those for January 
and March, 1867, being deficient), during which period the 
register runs parallel with that kept at the Literary Institution. 
—I have accordingly closely compared these registers for the 
period in question, omitting the same months in the examination 
of the Institution register that are omitted in the Ensleigh register, 
in order more strictly to preserve the parallelism between them. 
Though three years’ observations would be very insufficient for 
determining the absolute climate of any particular locality, they 
_ serve to indicate its relative character compared with another 
locality not far distant ; the general conditions of the weather and 
seasons during that period being the same for both.—The
