bodies as the Cotteswold Club. 
I asked the Secretary to give us a paper which might

Richardson’s suggestion, I have endeavoured to fill the 
gap by putting together a few notes on daily weather 
charts and the system of forecasting. 
The forecasting of weather is one of the oldest forms of 
prophecy, but it is one which is now, as more and more is 
understood of the conditions accompanying the incessant 
changes which have to be dealt with, gradually coming 
into the category of wise prophecy, z.e., of what is known 
only. 
Of all the instruments in use for the purpose, the 
barometer (invented about 180 years ago) is the principal
