By distilling the _Rosmarinus officinalis_ a thin limpid otto is procured, having the characteristic odor of the plant, which is more aromatic than sweet. One cwt. of the fresh herb yields about twenty-four ounces of oil. Otto of rosemary is very extensively used in perfumery, especially in combination with other ottos for scenting soap. Eau de Cologne cannot be made without it, and in the once famous "Hungary water" it is the leading ingredient. The following is the composition of HUNGARY WATER. Rectified alcohol, 1 gallon. Otto of English rosemary, 2 oz. " lemon-peel, 1 oz. " balm (_Melissa_), 1 oz. " mint, 1/2 drachm. Esprit de rose, 1 pint. Extract of fleur d'orange, 1 " It is put up for sale in a similar way to eau de Cologne, and is said to take its name from one of the queens of Hungary, who is reported to have derived great benefit from a bath containing it, at the age of seventy-five years. There is no doubt that clergymen and orators, while speaking for any time, would derive great benefit from perfuming their handkerchief with Hungary water or eau de Cologne, as the rosemary they contain excites the mind to vigorous action, sufficient of the stimulant being inhaled by occasionally wiping the face with the handkerchief wetted with these "waters." Shakspeare giving us the key, we can understand how it is that such perfumes containing rosemary are universally said to be "so refreshing!" SAGE.--A powerful-scenting otto can be procured by distillation from any of the _Salvieae_. It is rarely used, but is nevertheless very valuable in combination for scenting soap. Dried sage-leaves, ground, will compound well for sachets. SANTAL.--_Santalum album_. "The santal tree perfumes, when riven, The axe that laid it low." CAMERON. This is an old favorite with the lovers of scent; it is the wood that possesses the odor. The finest santal-wood grows in the island of Timor, and the Santal-wood Islands, where it is extensively cultivated for the Chinese market. In the religious ceremonies of the Brahmins, Hindoos, and Chinese, santal-wood is burned, by way of incense, to an extent almost beyond belief. The _Santala_ grew plentifully in China, but the continued offerings to the Buddahs have almost exterminated the plant from the Celestial Empire; and such is the demand, that it is about to be cultivated in Western Australia, in the expectation of a profitable return, which we doubt not will be realized; England alone would consume tenfold the quantity it does were its price within the range of other perfuming substances. The otto which exists in the santal-wood is readily procured by distillation; 1 cwt. of good wood will yield about 30 ounces of otto. [Illustration: Santal-wood.]
