454 C. Davison — British Earthquakes of 1890. 



After this prominent vibration, or " blow," the tremulous motion 

 was again felt, and lasted for five seconds. During the whole time 

 that the tremors lasted, a sound was heard " resembling the noise of 

 stones falling down a chimney," loudest at the moment when the 

 "blow" was felt, a dull "thud" being then heard "as of a sup- 

 pressed explosion." 



The intensity was V. at Clachan, and at Tarbert not less than IV. 



About noon on the same day, a second shock was felt at Clachan ; 

 but, so far as I know, by one observer only.

Earthquakes at Invergarry and Feddan. 

 The earthquakes at these two places ^ are interesting owing to 

 their possible connexion with the great fault which follows approxi- 

 mately the course of the Caledonian Canal. Invergarry lies about 

 a mile N.W. of the centre of Loch Oich, and Feddan about three 

 miles N.W. of the centre of Loch Lochy. For the following lists 

 I am indebted to the kindness of Mr. John Grant, of Invergarry, 

 and Mr. Murdoch Matheson, of Feddan, both of whom are doing 

 most valuable work in recording the occurrence of earthquake-shocks. 



Invergarry. 

 Jan. 5. 2h. 30m., a shock of intensity IV. 

 16h. 35m. 

 16h. 40m. 

 „ 16h. 47m., like a heavy carriage passing. 



Jan, 19. 16 h. 55 m., the same. 



Mar. 15. 8h. 45m., resembled the noise of a heavy train. 

 May 29. 16h. 45m., like a heavy carriage passing. 

 Aug. 8. 15h. 35 m., the same. 



Nov. 16. 20h. 30m., like a passing train. Though occurring at 

 the same time as the fourth shock of the Inverness 

 series, this must have been a distinct shock. 

 Dec. 1. lOh. 10m., a slight shock. 



Feddan. 



Nov. 19. Ih. 33m., a very slight shock, preceded by a low 

 rumbling noise. 



Dec. 26. ISh. 10m., a loud noise resembling thunder heard, 

 followed by a trembling motion, lasting fully two 

 minutes. Almost immediately afterwards, another 

 and louder sound was heard, without any accompany- 

 ing tremor. 



1 At both places, the shocks are recorded by only one observer, and should there- 

 fore, strictly, be regarded as doubtful shocks ; but I have placed them under a 

 separate heading, as both observers have for several years diligently, recorded the 

 occurrence of every shock felt by them.
