VII. Results of Meteorological Observations taken at Hdin- 
burgh during 1892. By R. C. Mossman, Ksq., 
F.R.Met.Soc., F.R.S.E. 
(Read 1&th January 1893.) 
The observations under discussion are those taken during 
the past year at the Edinburgh Station of the Scottish 
Meteorological Society, situated in the south side of the 
city, at an elevation of 254° feet above mean sea-level. 
The distance from the sea is about 2 miles. Observations 
have now been made at this station since 1886. It may be 
mentioned in passing that all the meteorological observations 
for the thirty years previous, or since the establishment of the 
Scottish Meteorological Society, were taken at stations within 
half a mile from the present site, and at the same altitude, 
so that the disturbing influences arising from difference 
of elevation, or change of position, or in the exposure of 
the instruments, are eliminated, when we come to compare . 
the earlier series of observations with thase made during 
recent: years. During the past year, as in previous ones, 
barometer readings have been taken twice a day, at 9 A.M. 
and 9 p.M.; those of the self-registering thermometers (maxi- 
mum and minimum) at 9 p.m. for the preceding 24 hours, 
those of the rainfall every morning at 9, and those of the 
hygrometer and wind twice a day, at 9 am. and 9 PM.
