Crystalline substance used to season food

Usage examples of salt.

Besides the glands, both surfaces of the leaves and the pedicels of the tentacles bear numerous minute papillae, which absorb carbonate of ammonia, an infusion of raw meat, metallic salts, and probably many other substances, but the absorption of matter by these papillae never induces inflection.

As such minute doses of the salts of ammonia affect the leaves, we may feel almost sure that Drosera absorbs and profits by the amount, though small, which is present in rainwater, in the same manner as other plants absorb these same salts by their roots.

We may infer that the carbonate of ammonia is absorbed by the glands, not only from its action being so rapid, but from its effect being somewhat different from that of other salts.

As, however, the aggregation caused by this salt travels down the tentacles at a quicker rate than when insoluble particles are placed on the glands, it is probable that ammonia in some form is absorbed not only by the glands, but passes down the tentacles.

This salt, when absorbed by the roots, does not cause the tentacles to be inflected.

If the volumetric method is to be used, the lead sulphate should be dissolved out with a solution of sodium acetate instead of with the ammonium salt solution.

In the case of ferric salts, half the quantity of acetic acid will be better, as then the ferric iron will be precipitated, and a colourless solution will be left, in which the end reaction is more readily distinguished.

From its behaviour with the dyes, and with tannic acid and metallic salts, it would appear that lanuginic acid contains both acidic and basic groups.

Cover with salted and acidulated water, bring to the boil, simmer for half an hour, drain, garnish with lemon and parsley, and serve with a parsley sauce.

Boil medium-sized sea-bass in salted and acidulated water, drain, and marinate with salt, pepper, and vinegar.

Cook the roes for five minutes in salted and acidulated water, drain, cut in two, and arrange around the fish.

Clean and trim a large striped bass, cut two incisions across the back, tie in a circle, and boil slowly in salted and acidulated water for forty minutes.

Clean and trim a striped bass and simmer half an hour in salted and acidulated water to cover.

Sew up the fish in a cloth dredged with flour, and boil in salted and acidulated water.
