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 ewt. 2 qrs., and the average 
of coals used to 1 ton of cast iron was 8 tons, 1 cwt. 1 qr. with the 
cold air; while in 1830, these numbers were respectively, 162 tons, 
2 ewt., 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-

no palms in the part of Palestine indicated by the memoir.” But, 
_ nevertheless, I find farther on in the Marshal’s communication, “ that 
there are a few at Jericho ;” that at Jerusalem, he saw three “ nearly
