In fair weather, when the mercury falls much and low, and thus continues for two or three days before the rain comes, then expect a great deal of wet, and probably high winds.
The unsettled motion of the mercury denotes uncertain and changeable weather.
The words engraved on the register plate of the barometer, it may be observed, cannot be strictly relied upon to correspond exactly with the state of the weather; though it will in general agree with them as to the mercury rising and falling.
When the thermometer and barometer rise together in summer, with rain in large drops, a wholesome state of the atmosphere is at hand.
A great and sudden rising of the barometer, that is to say, a great accession of atmospherical pressure, will, in some persons, occasion a slight temporary difficulty of hearing and tingling in the ears, similar to that which is experienced in descending from high mountains, or from the air in balloons.—Foster.
Barrel, s. A round wooden vessel to be stopped close; a vessel containing liquor; anything hollow, as the barrel of a gun; a cylinder.
Barrel-making has occupied the attention of gun manufacturers from the first invention of fire-arms to the present time. Experiments in the material as well as the construction of barrels, have been extensively tried by the artists of every country. A gradual and progressive improvement was the result, until the slub-barrel of the present day has superseded every other kind, and seems to have reached the utmost perfection that human ingenuity can accomplish.
The peculiar formation of barrels at different periods, and by different artists, will be interesting to sportsmen generally.
Spanish barrels have always been held in great esteem, as well on account of the quality of the iron—which is generally considered the best in Europe—as because they possess the reputation of being forged and bored more perfectly than any others. It should be observed, however, that of the Spanish barrels, those only that are made in the capital are accounted truly valuable; in consequence of which a great many have been made at other places, especially in Catalonia and Biscay, with the names and marks of the Madrid gunsmiths. They are also counterfeited at Liege, Munich, &c.; and a person must be a good judge not to be deceived by these spurious barrels.
These barrels were formerly in such high repute, that the price of them was enormous. Those of Belen, Fernandez, and Bez, sold in France for a thousand livres, or 43l. 15s.; while the barrels of artists of lesser name produced three hundred, or 13l. sterling.
