A Practical Manual On Sea Water Distillation
With A Description Of The Necessary Machinery For The Process

i7 CHAPTER III . COMPOSITION OF SEA WATER. Generally. 1. The word “sea” is usually applied indiscriminately to the open sea, so as to include the Ocean, while “ Sea ” and “Sea Water ” are usually applied to every large area of salt water, however and wherever situated. For deal- ing with this water in a treatise on its distillation it is necessary to divide the subject of sea water into “ ocean water and “ inland sea water/’ the latter including such large areas of water as the Mediterranean, the Baltic, and other extensive seas, which are either large inland lakes, or so land-locked as to be of a different character from the ocean. (a) Ocean Water—Its Composition. 2. Ocean water is fairly uniform in its composition— the quantity of saline matter it contains is not only fairly uniform in its proportion to the water it is dis- solved in, but the salts (especially those which are most m evidence) are fairly uniform in their proportions amongst themselves. 3. The actual water in ocean water or in sea water *8’ of course, always the same. As already mentioned ln an earlier part of this book, water is composed
