SEIDLITZ WATER, the product of certain saline springs in Seidlitz or Sedlitz, a village of Bohemia near Bilin, used as an agreeable and effective aperient. The solid contents in a wine pint, according to Bergman, are 192*8 grains, consisting of sulphate of magnesia, 180 grains ; sulphate of lime, 5 ; chloride of mag- nesium, 4'5 ; carbonate of magnesia, 2'5 ; car- bonate of lime, 0*8. To prepare an artificial Seidlitz water, dissolve from -J to 1J oz. of sulphate of magnesia in three times its weight of water, and, after filtering, introduce it into a bottle, to be filled with water charged with carbonic acid gas. SEINE (anc. Sequana}, a river of France, rising in the department of C6te-d'Or, on the slope of Mt. Tasselot, flowing first N. W., then W. 8. W., and again N. W., through the depart- ments of Aube, Seine-et-Marne, Seine-et-Oise, Seine, Eure, and Seine-Infdrieure, and falling into the English channel between Havre and Honfleur. The direct distance from its source to its mouth is 250 m., but its windings make it nearly 500 m. long. It is navigable for large vessels to Rouen, and for small vessels 350 m. to Mery-sur-Seine. It is connected by canals with the Loire, the Saone and Rh6ne, the Somme and Scheldt, and the Ourcq. Its ele- vation at its source is about 1,500 ft. above the sea. At Paris its width is from 300 to 500 ft., and at its embouchure about 7 m. Its chief tributaries on the right are the Aube, Marne, and Oise, and on the left the Yonne, Loing, Essonne, Eure, and Rille. The princi- pal towns on its banks are Chatillon, Bar-sur- Seine, Troyes, Nogent, Melun, Paris, Poissy, Mantes, Rouen, and Havre.

The Seine flows through the department very circuitously from S. E. to N. W., and the Marne joins it from the eastward. The most valuable mineral pro- ductions are excellent building stone and gyp- sum, producing plaster of Paris. The soil is fertile, and cultivated with great care. Capi- tal, Paris.

Millstones, sand- stone, paving stone, gypsum, chalk, and pot- ters' clay are found; and there are sulphur springs. The soil is not naturally very fer- tile, but it is carefully cultivated. The manu- factures include cloth, hosiery, paper, fire- arms, and Sevres porcelain, the last, which is conducted by the government, being the most important.
