to a red heat, and 31J cubic feet of olefiant gas came over. This gas wasnot fit for the purposes of illumination. Of crude pyrolignous acid, therewas 1J 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. Thepyrolignous acid, in the crude state, is sold in large quantities at 7 d. per gal-lon. It may be obtained from the loppings of the larch trees. Charcoal, inlarge quantities, varies in price from It. Id, to Is. 8 d. per bushel. Pieces ofwood 29 in. in length, and 4 in. in diameter, could easily be converted intocharcoal, for which there is a demand in this country to the value of10,000/. yearly.”

Some examples are next given of the elasticity, durability, strength, andresilience of larch timber ; but, as they are at great length, and illustrated byminute 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 originalpaper in the Highland Society’s Transactions , vol. xi. p. 165. to 219.
