bly prevented my feeing that ftrange phasnVDmenon : 
but the beft account I have got of it is from Angus 
M‘Diarmid, inn-keeper at Tarbat, who was an eye- 
witnefs, and was with his watch in his hand all the 
time of the agitation ; and his account is as follows : 
On the firft day of November laft, Loch Lom- 
mond all of a fudden, and without the leaft guft of 
wind, rofe againft its banks with great rapidity, but 
immediately retired, and in five minutes time fub- 
fided, till it was as low in appearance as any body 
then prefent had ever feen it in the time of the greateft 
fummer -drought ; and then it inftantly returned to- 
ward the fhore, and in five minutes time rofe again 
as high as it was before. The agitation continued .at 
this rate from half an hour paft nine in the forenoon 
till fifteen minutes after ten, taking five minutes to 
rife, and as many to fubfide; and from fifteen mi- 
nutes after ten, till eleven, every rife came fomewhat 
fliort in height of the one immediately preceding, 
taking five minutes to flow, and five to ebb, until 
the water fettled as it was before the agitation. Angus 
M‘Diarmid meafured the height, to which the loch 
rofe, and found it to be two feet four inches perpen- 
dicular. Loch Long and Loch Ketterin were alfo 
agitated on the fame day, and about the fame time ; 
but the phaenomenon was not fo minutely obferved 
as that any exadf account can be got of it. 
It appears, by communications fent from abroad, 
that the like agitations of the water were ob- 
ferved at the Hague, Leyden, Harlem, Am- 
fterdam, Utrecht, Gouda, and Rotterdam, and 
alfo alfo at Bois-le-Duc’ ; about eleven of the 
clock on the ifl: of November; and likewife
