The concluding observations of the last paper [1 — 28.] had 

 reference to some examples of the connection of the winds and 

 terrestrial heat which occurred in September, 1834. I shall 

 commence the present communication with observing, that an 

 earthquake occurred at Comrie, in Perthshire, on August 25. 

 1834, concurrent with the gale of wind experienced by 

 H.M.S. Thetis in the Irish Channel (VIII. 12.). The phe- 

 nomena observed in Europe about August 27. (VIII. 12. and 

 13.) were also very peculiar. I have been favoured with the 

 following additional particulars : — The weather at Rome 

 and Naples, during the whole of the summer of 1834, was 

 extremely hot. The thermometer at the former place was 

 constantly (with the exception of a few rainy days) from 25° 

 to 30° R. (89° to 100° F.) ; and at Naples from 25° to 28° R. 

 (89° to 95° F.), up to August 25. ; and, afterwards, at Naples, 

 during the three following months, at 82°, 77°, 71° F. On 

 August 27. the weather at Rome was so extraordinary, that 

 no parallel to it was remembered : the air appeared filled 

 with dust; the thermometer mounted up to 32° R. (104° F.), 

 the wind blowing strong from the south. At the elevation of 

 100 ft. above the earth, the thermometer at the Observatory 

 marked 29° R. (98° F.) Several persons were taken ill 9 and 

 several died suddenly. This was, at the time, attributed to an 

 eruption from Vesuvius (the distance is 154 miles), which,
