Rosa contifolia, L. 
The Cabbage Rose. Indigenous on the Caucasus and seem- 
ingly also in other parts of the Orient. Much grown in 
South Europe and South Asia for the distillation of Rose- 
water and Oil or Attar of Roses. From 12,000 to 16,000 
roses, or from 250 lbs. to 300 lbs. of rose-petals are required 
according to some calSulations, for producing a single ounce 
of Attar through ordinary distillation. The flowers require 
to be cut just before expansion ; the calyx is separated and 
rejected ; the remaining portions of the flowers are then 
subjected to aqueous distillation, and the saturated rose- 
water, so obtained, is repeatedly used for renewed distilla- 
tion, when from the overcharged water the oil separates on 
a cold place and floats on the surface. But some other 
methods exist for producing the oil, for instance it may be 
got by distilling the rosebuds without water at the heat of 
a saltwater bath. The odor may also he withdrawn by 
alcoholic distillation from the Roses, or be extracted by the 
“ enfluerage ” process. The latter is effected by placing the 
flowers, collected while the weather is warm, into shallow 
frames covered with a glass-plate, on the inner side of which 
a pure fatty substance has been thinly spread. The odor of 
the flowers is absorbed by the adipose or oleous substance, 
though the blossoms do not come with it in direct contact ; 
fresh flowers are supplied daily for Aveeks. The scent is 
finally Avithdrawn from its matrix by maceration with pure 
alcohol. Mr. Jos. Bosisto’s method for obtaining the most 
delicate and precious volatile oils will likely be applicable 
also to the Rose, and prove more advantageous both in labor 
and gain than any other process. Purified Eucalyptus-oil 
can be used for diluting Rose-oil, when it is required for the 
preparation of scented Soap. 
Rosa Damascena, Miller. 
Orient. Allied to the preceding species, and also largely 
used for the production of essential Oil of Roses. 
Rosa Gallica, L. 
The French or Dutch Rose. Middle and South Europe, 
Orient. The intensely colored buds of this species are par
