VOL. XV. (2) NOTES ON A DAILY WEATHER CHART 159 
indication, and then, when downstairs having looked at the 
barograph, if you use your wits, a walk, especially in thin 
shoes, of 200 yards, over gravel, grass and turned-up 
‘garden mould, will enable you, remembering or referring 
to yesterday's temperature, and recognising and valuing 
all personal and other indications, to say, within a degree, 
what reading you will find in the screen. 
There is a satisfaction in doing this right for several 
days together, perhaps even to one degree, and when you 
go wrong by 5° or more, you may put it down to some 
cause not sufficiently recognised and estimated, and learn 
to do better; you must, also, expect to find your per- 
ceptions varying with, and indeed largely dependent upon, 
a fairly healthy state.of body and mind. 
The rainfall can, also, by observation of the tread of the 
soil, be estimated, and, in a time of much rain, it is easy 
to judge the number of hundredths of an inch in the 
bottle before measuring it in the small glass. 
In the course of a discussion, which followed the reading 
of these notes, Mr Embrey drew attention to a conclusion 
which he had arrived at, by a study of a long series of 
weather charts, viz., that when a system of parallel isobars 
from east to west are shown, an uncertain forecast will 
follow, and constant changes may be expected ; but that if 
the isobars are north and south, and there is an anti-cyclone 
to the west, then settled weather will follow. But it is 
important that the isobars should show a regular curve ; 
for, if they are indented, secondary cyclones are indicated, 
and uncertain weather will follow.
