At Blair Goivrie, and in the glens of the Shee and the 

 Airdle, situated in the mica and clay slate formations, about 

 forty miles N.E. of Comrie, the effects of the shock are thus 

 described by the same correspondent, whose account of the 

 shock felt on the 12th October has already been given. He 

 says, — *' This shock was much more severe, and was very sen- 

 sibly felt in this town and neighbourhood, and very jtrongly 

 in Glenshee and Strathardle. In this town and its vicinity, 

 the shock was preceded by a sound similar to that already de- 

 scribed, which was immediately followed by a tremor or vi- 

 bration of the earth, making the furniture rattle and tremble ; 

 and, in one or two instances, forcing open doors that were 

 partly shut. According to some, the floors of the houses were 

 felt distinctly to heave like a wave, and afterwards to tremble 

 violently for some seconds. In my own case, the feeling was 

 as if a strong gust of wind had suddenly swept over the house 

 with a hollow sound, making the doors and windows rattle. 



" In the valleys of Glenshee and Strathardle, as already 

 mentioned, the concussion was felt much more violently, more 

 especially in the former, where several persons were awakened 

 from their sleep by the motion, and felt very much alarmed. 

 Some who happened to be standing outside the houses, and 

 close to the walls, felt as if the houses would fall to the ground. 

 The person already mentioned, who felt the former shock in 

 the hill, states that he felt his bed as it were lifted up from 

 4:he west or north-west, and let down again, like a boat by a 

 wave, and immediately afterwards the plates and other furni- 

 ture rattled strongly. Another person, who happened to be 

 sitting with his back to a wall, which ran in «, direction from 

 north to south, felt it incline over from the west, and rose hi 

 great alarm, under the idea that it would immediately fall. 

 At the Spittal of Glenshee, and also at Kirkmichael in Strath- 

 ardle, the concussion was very strongly felt, and in the same 

 manner. The most general opinion seems to be that the noise 

 accompanying the concussion proceeded from above. The 

 sound continued for about half a minute, and the tremor nearly 

 a minute. The shock occurred about 20 minutes past 10 p.m. 

 Two other shocks were subsequently felt, one about 11 on the 

 same evening, and the other about 2 o'clock next morning,
