Miscellanies. 183 



From a table appended to this paper, and furnished by Colin Dun- 

 lop, Esq., it appears that in 1829, the average weekly product of 

 the Clyde iron-works was 110 tons, 14 cwt. 2 qrs., and the average

 cold air; while in 1830, these numbers were respectively, 162 tons, 

 2 cwt., 1 qr., and 5 tons,. 5 cwt. 1 qr. with heated air ; and in 

 1833, 245 tons, and 2 tons, 5 cwt. 1 qr., also heated air. The fol-

 the cultivation of the vine, is also called in question. We here 

 transcribe this portion of the memoir, in order that botanists them-
