    Heated with free access of air, it burns, leaving no residue. With sulphuiic acid it forms a colourless solution. -It is soluble in eighteen parts of boiling distilled water, forming a clear, neutral, inodorous solution which, when cool, is not affected by solution of perchloride of iron. Heated with soluiion of potash and a few drops of chloroform, the unpleasant odour of phen}l- isonitrile is develoj^ed. Dose.—3 to 10 grains. Therapeutics.—l^ebiifuge, anti-pyretic, anti-epileptic, anti- arthritic, a hypnotic sedative and nervine tonic. It has becTi given in delirium tremensj,; is stated to check the chills and fever of phthisis, and relieve the darting pains of locomotor ataxia. It has been recommended f'T diphtheria and scarlatinal and other forms of sore-throat, and also in the treatment of epilepsy. It is useful as a local application in psoriasis, ery- sipela.3, and acne (twenty grains to an ounce of lanoline or vaseline). Also said to be a valuable hypnotic for children. ADEPS LAN^. Wool-fat. This is the purified cholesterin-fafc of sheep's wool. Characters and Tests.—A yellowish tenacioiis unctuous sub- stance ; almost inodorous ; with a melting-point varying from lOO^Fabr. (37°'8 0.) to 112°rahr. (44°'4C.) ; readily soluble in ether and in chloroform, sparingly soluble in rectified spirit. Ten grains should dissolve almost completely in fourteen fluid drachms of boi'ing ethylic alcohol, the greater part separating in flocks on cooling. Ignited with free access of air, it burns, leaving but a trace of ash. Fifty grains dissolved in four fluid drachms of ether, and two drops of tincture of phenolphthaltin added, should not require more than two grain-measures of volumetric solution of soda to produce a permanent red colora- tion. The solution in chloroform poured gently over the surface of sulphuric acid acquires a purple-red colour. Heated with solution of soda, no ammoniacal odour should be evolved. Wool-fat is used in the following preparation : ADEPS LAN.ffi HYDROSUS. Hydrous Wool-fat. This preparation is commonly known as Lanoline. It is pre- pared as follows : Wool-fat (7 oz.) is melted in a warm mortar, distilled water (3 oz.) being stirred in gradually and thoroughly. Characters and Tests.—Yellowish white ; free from rancid odour. When heated it separates into an upper oily and lower aqueous layer. One hundred grains exposed over a water-bath until the weight is constant, yields not less than seventy grains, which should answer to the tests for wool-fat.
