To be converted by the sodium carbonate into a form of soap which is soluble in water. The emulsification of fat is known to occur in the small intestine. By this process the fat is separated into minute particles which are suspended in water, but not changed chemically, the mixture being known as an emulsion.

The treatment is to wash out the stomach with large and weak solutions of carbonate of sodium. Mucilaginous drinks may be given, and hypodermic injections of morphine are useful to allay the pain. Method of Extraction from the Stomach. Dry and incinerate the tissues in a porcelain crucible, digest ash in water, apply tests. Tests.

Physiologists generally admit water facilitates nutritive exchanges, which is explained by the elimination of a large quantity of urine; the experiments of Genth and Robin in this direction appear conclusive. Bischoff, Voit, and Hermann have shown that water increases, not alone the elimination of urine, but also of sodium chloride, phosphoric acid, etc.

Those of relatively-low molecular weights oxygen, hydrogen, potassium, sodium, &c., show great readiness to unite among themselves; and, indeed, many of them cannot be prevented from uniting under ordinary conditions.

Reeks has analysed for me some of the salt from the salina near the Rio Negro; he finds it composed entirely of chloride of sodium, with the exception of 0.26 of sulphate of lime and of 0.22 of earthy matter: there are no traces of iodic salts. Some salt from the salina Chiquitos, in the Pampean formation, is equally pure.

The dehydrating agents rapidly lose their efficiency on exposure to the air. It is often necessary in quantitative analysis to employ fluxes to bring into solution substances which are not dissolved by acids. The fluxes in most common use are sodium carbonate and sodium or potassium acid sulphate.

In this test the ordinary healthy man shows normal 30 to 50: the scurvy patient normal 90. Lactate of sodium increases alkalinity of blood, but only within narrow limits, and is the only chemical remedy suggested. So far for diagnosis, but it does not bring us much closer to the cause, preventives, or remedies.

The small doses of sodium iodid, perhaps 0.2 gm. Iodid in this dosage does no harm and may do a great deal of good.

Sodium chloride being the principal noxious element in sea water, and soda in combination with a vegetable or organic acid, such as citric acid, tartaric acid, or malic acid, being innocuous, the conclusion is that the element of evil to be avoided is chlorine.

Besides the characteristic substances of these three classes, protoplasm contains certain other chemical compounds, like the various salts of sodium, chlorine, magnesium and potassium, and a few others, which bring the list of chemical elements to the number twelve.
