53 'So degrees, or a little warmer in the days and a little colder in the 

 nights than usual in August month. 



On three days during the month the sun was not visible, the 

 winds were moderate except on the 14th and at the close of the 

 month. 



The excursion of the Royal Institution of Cornwall to Dolcoath 

 and Tehidy was made amidst this wind and rain ; few will forget 

 how they met those who were journeying over the hill near to 

 Redruth. Our rainfall during the excursion this year was not 

 continuous, the total rainfall being 0*30 inch, or under one-third of 

 an inch ; last year, when the excursion was to Padstow and Prideaux 

 Place, the downpour was 1*48 inches, nearly one and a-half inches 

 of rain, about five times as heavy as on this year's outing. 



Just after midnight on the morning of the i8th, earthquake 

 shocks were felt throughout Cornwall. Perhaps an epitome, 

 without any explanation of the causes of earthquakes, would be read 

 with interest. Direction : south to north. Duration of shock : 

 probably from three to thirty seconds. Effects : a general 

 awakening of people, rattling of windows, doors, and crockery, 

 shaking of houses, and earth tremors. The following are a few 

 Cornish impressions : — " Sharp shock " (Penzance) 3 "Perceptible 

 shake of the earth " (Redruth) ; " Perceptible motion of the earth, 

 bed seemed to be lifted from the floor, watch was thrown down 

 and glass smashed" (Truro) j "Furniture was in a state of 

 perturbation " (St. (Blazey) ; " Noise resembled that of a rumbling 

 waggon" (Lostwithiel) ; "Noise of falling bricks, a low 

 rumbling sound ' (Helland) ; " Curious trembling of houses without 

 any noise ' (Callington) ; "Walls vibrated, and china and other 

 articles distinctly rattled" (St. Cleer) 5 "Loud noise somewhat 

 resembling the sound of thunder " (Liskeard) ; " Slates on the roof 

 rattled" (Tregeare, near f.aunceston) 5 many in Truro say they 

 felt the shock, personally, I was totally oblivious. 



Further records of the occurence of the Clouded Yellow butterfly 

 Colias edusa., Fabr., in many localities have been sent me, and 

 Mr. Davey saw in Kennal Vale as pecimicn of the Pale Clouded 

 Yellow, Cvlias hyale, L. Although we have had so exceptional a 

 summer for butterflies — and these insects have been very common, 

 too — yet the dense flights of the Clouded Yellow, so frequent in 

 1877, have not been observed.
