1. Notice respecting the Drying-iip of the Rivers Teviot, 

 Clyde, and Nith, and their tributaries, on the 27th No- 

 vember 1838. By David Milne, Esq. 



The phenomenon was in the first instance described, and certain 

 views wei*e afterwards oiFered explanatory of it. 



It appears that, betwixt 10 p.m. on the ^6th November, and 

 6 A. M. on the 27th November, the channels of the Teviot, Clyde, and 

 Nith, became nearly dry i'or a great part of their course, so tliat 

 scarcely any current flowed in them. All tiie mills on the Clyde, as 

 far down as several miles below New Lanark, were stopped from 

 want of water. The Nith was nearly dry as far down as Enter- 

 kinefoot ; and the mills on it, and on its tributaries, were stopped. 

 This was the case also on the Teviot. The phenomenon was most 

 strikingly manifested in the higher parts of the rivers, near their 

 sources. The small streams from which they derive their supplies, 

 were in general completely dried up. Tiie rivers, in the lower 

 parts of their course, were not entirely deprived of their current ; 

 nor were the rivulets, which there supplied them, nearly so much 

 affected as the rivulets in more elevated districts. 

 . The desiccation continued all the morning, forenoon, and part of 

 the afternoon of the •27th November. When the current was re- 

 stored, it returned not with a sudden rush, but gradually ; nor when 

 the current was restored, did the waters rise much above their or- 

 dinary level.
