218 NOTES: ON SOME RECENT BAROMETRIC DISTURBANCES. 
ments that — a gale of wind blows against a high wall, the 
barometer shows a greate “ict gt to windward than to leeward, 
but thoaretivalby it should not do so. And another fact which all 
who have watched the barometer here will remember, as soon 
as I mention it is, that when a southerly gale comes on, the 
arometer rises rapidly, and this is owing to the ar aig exerted 
ns the incoming wind forcing up the local wind, as may be seen 
peculiar rolling clouds, and in the fact that such a wind 
with a velocity of from 60 to 70 miles per hour will take from 
one and a half to two hours to travel from here to N: eweastle, a 
ee of 60 miles. J confess I have some difficulty: in aecept- 
ing some of the conclusions which an crane ag ot this storm 
have led me to. But whether we accept its velocity and size or 
not, there can be no rere that thunderieteriie do affect the 
barometer as I have stated—that is, by a sudden rise as they 
come in, and an pcos saddens fall after they are past.
