ON ATMOSPHERIC WAVES. 
351 
Fourth Report on Atmospheric Waves. By W, R. Bikt. 
In accordance with the resolution adopted at the last meeting of the British 
Association, I have the honour to report that about thirty sets of observations 
have been obtained from various stations in the British Islands: the extreme 
points of the area embraced by these stations are the Orkneys and Jersey in 
one direction, and Galway anti Dover in the other. The observations liave 
been execoted with great care by the respective observers, and mostly at the 
hours named in the instructions. In some cases the observations have been 
continued through October, Noventber and December; in others, they com¬ 
mence about tlie middle of October and teniiinats at the end of November. 
As instances of the increasing inti^rest manifeated on this subject, 1 have the 
pleasure to notice that I have been furnished with curves from stations in the 
North, where the barometric movements have been considered to result from 
the transit of the great November wave. 'Hiesc curves arc referred in each case 
to the same period, namely, from the 2nd to the 17th of November; and the 
observers have invariably regarded the regular rise and fall that occurred 
between these epochs as indicating a well-marked return of the great sym¬ 
metrical wave. 
Observations .—The following Table contains the* names of the stations and 
observers from which observations have been received: it is rlglit to mention 
that a scries of observation* was received from Birmingham, but the curve 
presents so many anomalies, that if. ha* not (except in some minor instances) 
been employed in deducing any of the succeeding results.
