CHAP. 34.—HOW ARTIFICIAL SEA-WATER MAY BE MADE IN PLACES AT A DISTANCE FROM THE SEA.
I am by no means unaware that these details may very possibly appear superfluous to persons who live at a distance from the sea; but scientific research has made provision against this objection, by discovering a method of enabling every one to make sea-water3099 for himself. It is a singular fact in connexion with this discovery, that if more than one sextarius of salt is put into four sextarii of water, the liquefying properties of the water will be overpowered, and the salt will no longer melt. On the other hand, again, a mixture of one sextarius of salt with four sextarii of water, acts as a good substitute for the efficacy and properties of the very saltest sea-water. The most reasonable proportion, however, is generally thought to be eight cyathi of salt, diluted in the quantity of water above mentioned; a preparation which has been found to have a warming effect upon the sinews, without in any degree chafing the body.
