Página 259 - 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.

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...
Página 237 - Mange has discovered that the pyroligneous acid, obtained by the distillation of wood, has the property of preventing the decomposition and putrefaction of animal substances. 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.
Página 177 - 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.

Página 176 - Every bunch of grapes commences its formation as a tendril, and it is always within the power of every cultivator to occasion it to remain a tendril. The blossoms are all additions, the formation of which is always dependent upon other agents : and if any considerable part of the leaves be taken off the branch prematurely, or if the vine be not subjected to the influence of the requisite degree of heat and light, the tendrils will permanently retain their primary form and office; and it is very frequently...

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.

The objects, which I have had it in view to determine by the following course of experiments, are, whether, on the large scale of manufacture, there is a decline in the value of the aeriform products of coal, from the beginning to the end of the distillation, similar to that which takes place on a small scale; — at what stages...
