Rising, Southing, and Setting of the Principal Planets 

 at intervals of Seven Days in July. 



more than the whole number of Science-Gossip. 

 What weather there has been will be seen in the 

 weekly summaries which appear below, but I must 

 mention that the Iith of July was colder in some 

 places than the corresponding day in January, and 

 the rainfall was between four and five times the 

 average, so that nearly 1000 tons of water fell to an 

 acre. 



The unfavourable weather has militated greatly 

 against astronomical observations being made, so 

 that there is less to chronicle than otherwise would 

 have been the case ; but this exceptional weather has 

 greatly increased the interest in meteorological results. 



As I was unavoidably prevented from writing my 

 paper on Astronomy and Meteorology last month, I 

 have given here the meteorological results of the two 

 months, as I believe they will be found exceptionally 

 interesting.
