On imparting Durability to Timber. 
Some remarkable facts respecting the durability that may be 
given to timber, by 'artificial means, have been observed at Close- 
burn. The proprietor of that estate has for thirty years been in 
the constant practice of soaking all fir and larch timber, after it is 
sawed into plank, in a pond or cistern of water strongly impreg¬ 
nated with lime. In consequence of this soaking, the saccharine 
matter in the wood, on which the worm is believed to live, is 
altogether changed or completely destroyed. Scotch fir-wood 
employed in roofing houses and other in-door work, treated in 
this manner, has stood in such situations for thirty years sound, 
without the vestige of a worm. In a very few years fir timber so 
employed, without such preparation, would be eaten through b y 
that insect. It might, perhaps, be advisable, in all timber used 
for ship-building, to soak it for some days in lime-water.

On the Gases contained in Cattle inflated by 
feeding too freely on Green Food. 
In the “ Bulletin de Pharmacie,” it is stated that this gas, 
when analysed, yielded sulphuretted hydrogen 80 parts, carbo¬ 
nated hydrogen 15, and carbonic acid 5. 
According to a recent analysis by Mr. Plugh, it contained 
three-fifths of carbonic acid, and two-fifths of carbonic oxide gas ;
