places, were steeper. A well-marked secondary depression,— 
possibly that which had been over St. Gieorge’s Channel, now 
lies just N.W. of York. The isobar of 29’2 ins. curves sharply 
round on the S.S.E.,and a corresponding bend affects the other 
lines passing through places where the barometer stood at 
levels differing by tenths of an inch. The points of such bends, 
for the isobars from 29T to 29-6 ins., form a curved line from 
Dumfries, through York, Leicester, Oxford and Weymouth, to 
S. of Land’s End. The main depression, with a record below 
29 inches, now lies N.W. of Malin Head.

The three following aneroidograms, as the traces of recording 
aneroid barometers may fitly be called (figs. 2, 4, 5), and the 
barogram of fig. 3, all show the passage of the secondary 
depression very clearly, forming a dip in the main curve of 
descent. Taking that at York (Fig. 2, about 10 mins, fast at
