223. oldal - Lieutenant Robertson, in a letter to the Honourable Captain Napier of Merchistoun, has spoken of it in the following manner : " The Sympiesometer is a most excellent instrument, and shews the weather far better than the Marine Barometer. In short, the barometer is of no use compared to it. If it has any fault, it is that of being too sensible of small changes, which might frighten a reef in when there was no occasion for it ; but, take it altogether, in my opinion it surpasses the mercurial barometer...

It is sufficient to plunge meat for a few moments into this acid, even slightly empyreumatic, to preserve this meat as long as you may desire.
145. oldal - London, and in every favourable situation, I preserve a large number of the young shoots, which are emitted in a proper direction in early spring by the yearling wood, shortening each where necessary, by pinching off the minute succulent points, generally to the length of one or two inches.

The quantity of quicklime required for the absorption of a cubic foot of carbonic acid, or of the same volume of sulphuretted hydrogen gas, will be found on calculation not to exceed 1050 grains, or about 2| ounces avoird.
