On Forecasting the Weather; by B. G. Jenkins. 
In forwarding the accompanying chart, which almost 
speaks for itself, 1 beg to call attention particularly to 
twọ points : 
First, it proves that not only has the moon an influence 
upon the weather, but that our satellite is the actual cause 
of it, and in that case an astronomical discovery of the 
highest importance has been made; an 
Secondly, if we can refer to a year which had practically 
the same weather as that which we are experiencing this 
year, it is of the greatest importance that the astrono- 
mical authorities of each country should utilise that know- 
ledge to the advantage of the commercial and agricul- 
tural industries of the community generally. 
By a process which it is not necessary for me to 
enter into now, I have found that the barometric and 
thermometric readings for London for this year, 1887, 
will be practically the same as those which have been 
recorded for the year 4825. If so, then those for 1885 
and 1886 should be practically the same as those for 
1823 and 1824. I find this is so. I have prepared a chart 
for these two sets of years, superimposing the readings of 
1885 on those for 1823, and the readings for 1886 on 
those for 1824. It is a matter of too great expense for me 
to have this chart reproduced in its entirety, but I have 
selected two months from each set of years, and a glance 
at the electro-photo, which accompanies this, will con- 
vince you that the similarity of features cannot be acci-
