![U.S.P. Sp. err. 0-725 to 0-738. Ph.G. Sp. gr. 0-720. iEther Aceticus. B.P., Ph.G. Sp. gr. 0-900 to 0-905. Consists chiefly of ethyl acetate. Obtained by distillation of a mixture of alcohol, sulphuric acid, and dried sodium acetate. Dose, 60 to 90 miiis., or in repeated doses 20 to 40 mins. U.S.P. Sp. gr. 0-893 to 0*895. C. Dried sodium acetate 10, alcohol (95 per cent.) 6, sulphuric acid 15. Add the sulphuric acid gradually to the alcohol contained in a flask, kept cool with cold water ; when thoroughly cold pour on to the powdered sodium acetate in a retort. Let stand in contact for 24 hours, then distil from a sand-bath. Shake the distillate with half its volume of saturated sodium chloride solution, decant, and then leave for 24 hours with one tenth its weight of dried potassium carbonate. Again decant, and re-distil from the water-bath. iEther Bromatus. Ph.G. Ethyl bromide. Mix sulphuric acid 12, alcohol (90 per cent.) 7 parts, and cool; then add potassium bromide 12 parts, distil on a sand-bath, wash the distillate first with 5 per cent, potassium carbonate solution, then shake cut twice with an equal volume of water, dry with calcium chloride, and distil from a water- bath. Sp. gr. 1-453 to 1-457. iEther Bromhydricus. C. Potassium bromide 12, sul- phuric acid 12, alcohol (95 per cent.) 7. Gradually add the acid to the alcohol in a capacious flask, kept cool by means of water. When cool, gradually add the bromide in powder, still keeping the mixture cool; then attach to a condenser and distil from a sand-bath into a receiver containing a little water. Wash the distillate with 5 per cent, solution of potash, decant, and wash thoroughly with water. Separate, and add calcium chloride to dry, leaving in contact for 24 hours; then transfer to a retort, add one tenth the volume of oil of sweet almonds, and re-distil from a water-bath at a temperature not exceeding 39° C. (102° P.). Keep in well-closed bottles in the dark. .aither Cantharidatus. A. S])anisc'hfiiegendt}ier. Can- tharides 10, ether (Ph.G.) 15. Pack in a percolator, and after macerating for 24 hours allow percolation to proceed until 10 parts are obtained. iEther Kydriodicus. C. Iodine 40, alcohol (95 per cent.)](https://iiif.wellcomecollection.org/image/b20401012_0029.jp2/full/800%2C/0/default.jpg)
