Sale. Transfer of property, or contract to transfer it, for a price in money; generally, in English law, movable personal property. It is sometimes difficult to determine whether a transaction is sale or bailment, lease or mortgage: but if it is to evenutate in the transfer of the general property in a chattel for a money consideration, it is a sale. In case of a contract for the present sale of a specific chattel, title passes upon the formation of the contract, though the seller has a right to retain the chattel until the price is paid; in case of a contract to sell in the future, title will pass as soon as the chattel is unconditionally appropriated to the contract by the act or assent of both parties. At common law, no one can give a better title to goods than he possesses (except in case of sales in market overt in England): but this has been modified to some extent by Factors' acts and other statutes.

Salmo. Genus of family Salmonidce, including S. salar, Atlantic Salmon, S. trutta, Sea-Trout or Salmon Trout, and the Black Spotted Trout of the rivers and lakes of Europe and w. N. America, of which S. fario, S. gairdneri, S. irideus, and <S. purpuratus are examples. The Atlantic Salmon is steel blue above, with black spots, most numerous in the female, distributed on the back. There are teeth on the vomer, which disappear with age. When the salmon runs up the rivers, the color fades and the male acquires orange patches and gets a more hooked under jaw. The average weight is less than 15 lbs., though an exceptional weight of over 80 lbs. is recorded. The salmon is rare in rivers s. of Cape Cod, although, before the Uudson, Delaware, and streams of N. J. were polluted by factory waste, they ran in these streams. After spawning.

the parents are called kelts, which, unlike the quinnat. do not perish, but return to the sea. The spawning is done in the fall and the eggs hatch as parrs the next spring. They remain in the river two years, descending the third spring. When a year old, the parr is called a pink, and when it descends the river, it is a smolt. In the sea it grows rapidly into a grilse, or young Sea Salmon. The parr has two or three black spots on the opercle, several black and orange spots on the back, and 12 to 15 bluish bars on the sides. As it becomes a smolt the fins get darker. The salmon which have become land-locked are the variety sebago. Salmo truttais a smaller, weaker fish, with smaller scales. Black Spotted Trout salmon of fresh water have the vomerine teeth persistent. S. fario is the European Trout, the corresponding American form being the

Rainbow Trout, S. irideus, which is believed to become the S. gairdneri or Steel-head as it grows older. It returns to the sea when the fall run of Quinnat occurs. These fish are small in small streams and in warmer waters, while in lakes and the north a weight of 20 lbs. (6 in the irideus) is attained. For the fish which is called Brook Trout, Lake Trout, etc., in e. U. S.( see SALVELINUS.

Salt. NaCl. Common salt is a chemical compound of sodium and chlorine. Though readily soluble in water, it is found abundantly in rock form as an important mineral component of the earth's crust. Rock salt, known mineralogically as halite, occurs in all the more extensive geological formations from the Silurian to the Tertiary, and is sometimes found in beds hundreds of feet in thickness and of great lateral extent. Salt is also obtained from the waters of the ocean, of salt lakes, and of salt springs, as well as from the deep-seated

Salts. Generally, crystalline compounds, formed by the treatment of an acid with abase. They consist of a metal and an acid radical; e.g., sodium sulphate, Na3SO<. Normal or neutral salts are those containing neither acid nor basic residues. They are derived from acids by the replacement of all the available hydrogen by a metal or metals. Acid salts are those derived from acids by replacing a portion of the available hydrogen by a metal; e.g., acid potassium sulphate, KHSOt. Basic salts are those derived from bases by replacing a portion of the hvdroxyl with an acid residue; e.g., basic bismuth nitrate, Bi(OH),NO„ derived from Bi(OH)s. Primary salts are those derived from polybasic acids by the replacement of one atom of hydrogen by a univalent metal; e.g., primary sodium phosphate is NaHjPO^ If the metal is bivalent, the primary salt is derived from two molecules of the acid: thus primary calcium phosphate is CaHi(P04)a. Secondary salts are those derived from the acid by the replacement of two atoms of hydrogen by the metal. In a tertiary salt the metal replaces three atoms, hydrogen, etc. Double salts are those
