 was U pint. Haifa gill of tar, of superior quality to that made from coal, 

 and 1 lb. 9 oz. of charcoal were the rest of the ingredients obtained. 1 he 

 pyrolignous acid, in the crude state, is sold in large quantities at Id. per gal- 

 lon. It may be obtained ti'om the loppings of the larch trees. Charcoal, m 

 large quantities, varies in price from l,v. id. to Is. Sd. per bushel. Pieces of 

 wood -29 in. in length, and 4 in. in diameter, could easily be converted into^ 

 charcoal, for which there is a demand in this country to the value ot 

 10,000/. yearly." 



Some examples are next given of the elastlcUy, dnrabUity, strength, and 

 resilience of larch timber ; but, as they are at great length, and illustrated by 

 minute tabular details, and as the general results have been given in a pre- 

 ceding part of this article, we omit them, and refer the reader to the original 

 paper in the Highland Society's Transactions, vol. xi. p. 105. to 219.
