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

COMPOSITION OF WATER. 2 I 25 parts of muriate of soda (common salt). 3 „ muriate of magnesia. 2 „ sulphate of magnesia (Epsom salts). 1 ,, sulphate of lime (plaster of Paris). 1 ,, sundries. 32 „ saline matter. 968 „ ordinary water. 1,000 parts—Total. 8. Dr. 1 idy found that sea water at Margate (at high tide) contained :— Total solids, . Chlorine, . Lime, Magnesium, Silica, Hardness, Per cent. . 3343 . 1’7705 . 0035 . 0-205 . 0-0004 . 0-564 9. The Rivers’ Pollution Committee found that sea water contained approximately as follows :— Free and saline ammonia, . A trace. Total solids, .... 3’893 per cent. Chlorine,__________________1975 „ 10. From a large number of specimens of ocean water, taken at various points of the world, it was found that the total salts averaged 3*5 per cent., ranging from 3 7 in torrid regions to 3'2 in frigid regions, and that water from a depth is not quite so saline as that at the surface. These results are what one would expect—viz.,
