oil (common and refined), and Rape-cake. The oil is commonly known 
as Rape oil, and the crushed residuum is much used for fattening cattle, 
under the name of Rape-cake. E 
Mustard. Seed, oil (Camphine Company), prepared mustards, with 
the dran or husks, and lawn-sieve used in separating the mustard used 
at table from the bran. (Mr. Spencer.) Two species are in general 
use in England; Sinapis alba, L., yielding the white or Essex mustard, : 
and Sinapis nigra, L., Cambridge brown mustard, Spanish mustard is 
probably from one of the above, though the plant is called by Lawson 
S. Hispanica. In India oil is extracted extensively, according to Dr. 
Alexander Hunter, from Sinapis Chinensis and S. glauca, as well as 
S. nigra. 
Sea-kale. Crambe maritima, L. Europe. Wild in England. Seeds, 
and wax model. A well known and delicate vegetable, much improved 
by the skill of the gardener. : 
Crambe Kotschyana, Boiss. Seinde. (Dr. Stocks.) Roots of this 
we have received as an esculent; as Crambe tartarica, L., is considered 
in Hungary. 
 Radish. Raphanus sativus, Z. Of this familiar root there are many 
varieties, if not hybrids, models and seed. il is yielded abundantly 
from the seed. 
Ord. CapPARIDEX. CAPER FAMILY. 
A group or family of no great importance; properties considered 
similar to those of Crucifere: few kinds are employed in Europe, 
except 
.  Capers. These are the flower-buds of a suffruticose plant, common 
in the South of Europe on rocks and walls, the Capparis spinosa, L., 
_ which has a prickly stem, as its botanical specific name implies, and 
bears large white flowers. In the warm parts of France and in Italy 
it is much cultivated. The flower-buds are gathered before expansion, 
. and preserved in vinegar, and they constitute a very considerable 
article of trade. 
Gum of Capparis scabrida, H. B. K., is brought to us from Puna, 
by Mr. Seemann, but of its properties we are ignorant. 
Wood of Capparis grandis, L. Madras. (Dr. Wight.) — ruis of other 
and unknown species of Capparidee, only of botanical interest. Cap- 
. paris excelsa of Madagascar is said to afford planks four feet broad.
