Not illustrated. 1900 Excerpt: ...material is the best for washing purposes, the dissolved substances in other specimens of tap water are by no means injurious to health when used to drink. On the contrary they are often beneficial; it is said that water which contains no chalk dissolved in it is not good for children because they require this substance in considerable quantities to build up their bones. Sea water.--As every boy and girl knows, sea water is often called salt water. The water of the ocean contains sufficient dissolved matter in it to make it taste, while in spring, rain, and river water the quantity is so small that the water is tasteless; for this reason the water of springs and rivers is often called fresh water. Streams and rivers are continually flowing into the sea and carrying into it the substances they have dissolved out of the land. Evaporation is unceasingly going on from the surface of the ocean, robbing it of pure water in the form of water vapour, with the result that there is an accumulation of soluble material in the water which is left. It would consequently seem at first as if the sea must everyday become Salter. This is certainly not the case. It would be so if it were not for the animals and plants which live in the ocean and extract from the water some of its dissolved material to build up their solid parts. Amount of dissolved material in different kinds of water.--The mass of a gallon of pure water is 70,000 grains, that is, 10 lbs. avoirdupois. It has been found by careful experiment that a gallon of water from the Dee, near Aberdeen, which flows SOLIDS IN DEE WATER, 3 GRAINS SOLIDS IN SEA WATER; 2450 GRAINS Fig. 18.--Comparative masses of a gallon of pure water, and of the solids found in river and sea waters. over a granite country, only contains th...
