Usage examples of grains.

Drosera in a state of nature cannot fail to profit to a certain extent by this power of digesting pollen, as innumerable grains from the carices, grasses, rumices, firtrees, and other windfertilised plants, which commonly grow in the same neighbourhood, will be inevitably caught by the viscid secretion surrounding the many glands.

A solution made with borax, two drachms, and morphine, fire grains, dissolved in six ounces of rose-water, makes an excellent lotion to allay the itching.

Twenty or thirty grains of the extract of male fern, followed by a cathartic is highly recommended for the destruction and removal of taeniae.

Instead of nutritive energy, which by assimilation produces perfect bodily textures, this function, in the scrofulous diathesis, is deranged by debility, and there is left in the tissues an imperfectly organized particle, incapable of undergoing a complete vital change, around which cluster other particles of tubercular matter, forming little grains, like millet seed, or growing, by new accretions of like particles, to masses of more extensive size.

The grains being then removed, and examined under the microscope, were found discoloured, with the oilglobules remarkably aggregated.

There could be no doubt that the secretion had penetrated the outer coats of the grains, and had partially digested their contents.

We have also seen that the delicate coats of pollen grains are not dissolved by the secretion.

On the other hand, in the slices surrounded by damp cottonwool, the grains of chlorophyll were green and as perfect as ever.

As I at first thought that the poison might not have been dissolved in pure water, one grain was added to 437 grains of a mixture of one part of alcohol to seven of water, and halfminims were placed on the discs of six leaves.

This leaf was now immersed in a little solution of one part of urea to 146 of water, or three grains to the ounce.

In the leaf itself, however, the grains of chlorophyll near the cut surfaces had run together, or become aggregated.

A stronger solution of two grains of this salt to an ounce of water, though exciting copious secretion, paralyses the leaf.

Even a very few grains which accidentally fell on a single gland caused the drop surrounding it to increase so much in size, in 23 hrs.

They thus differed in appearance from other grains kept in water for the same length of time.

Even a few grains of pollen on a single gland causes it to secrete copiously.
