to a red heat, and 3U cubic feet of olefiant gas came over. This gas was 

 not fit for the purposes of illumination. Of crude pyrolignous acid, there 

 was H pint. Half a 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. The 

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

 lon. It may be obtained from the loppings of the larch trees. Charcoal, in 

 large quantities, varies in price from Is. r ld. 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 elasticity, durability, 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. 165. to 219.
