new varieties, and chiefly by layers for continuing approved sorts. Tlicy 

 are also increased by budding, cuttings and suckers. Extracting tbe 

 stamens from one flower, and dusting the stigmas with the pollen of 

 another kind, will sometimes answer a most admirable pm"pose. The 

 tips generally ripen in October or November, and the seed does not 

 vegetate till the second year after sowing. 



Medical Properties and Uses. The petals of this rose possess a 

 very highly fragrant odor, which is not entirely dissipated by keeping, 

 but some of the flavor is lost unless used fresh ; the rose-water is dis- 

 tilled from petals recently gathered; their taste is sweetish and slightly 

 bitter. Water extracts the odor of the petals both by infusion and 

 distillation ; and when large quantities of them are employed in 

 the distillation, a very small portion of yellow, fragrant, butyraceous 

 essential oil is sometimes procured, which is of a very mild nature, 

 possessing no pungency. They also give out a bitter principle to 

 water, but alcohol is their best menstruum. They are chiefly used as 

 a perfume. The otto of roses, which is procured from this species, 

 has a most powerful and fragrant odor, and is exceedingly diff"usible. 

 They are slightly laxative, but are rarely administered medicinally, 

 except occasionally to children ; the chief use to which the petals are 

 applied in this country, is for the distillation of rose-water, which pos- 

 sesses no medicinal virtues, and is only used on account of its agree- 

 able odor 



Aqua Roscc. Rose-water. U. S. Dispensatory. Take of fresh 

 hundred-leaved roses, or petals, eight pounds, water two gallons ; mix 

 them and distil one gallon. The Dublin College orders a gallon of 

 the water to be distilled from eight pounds of the petals. The Lon- 

 don College takes ten pounds of roses, seven fluid ounces of proof 

 spirit, and two gallons of water, and distills one gallon. The Edin- 

 burgh College proceeds the same as the London, substituting three 

 fluid ounces of rectified spirit for seven of proof spirit, and adds the 

 following notice : " The petals should be preferred when fresh, but it 

 also answers well to use those which have been preserved by beating 

 them with twice their weight of muriate of soda."
