I strongly suspect not without some exceptions, as we do not in all the instances cited, find it 
combined with aromatic properties, any more than in Ranunculacee. It is sai however, to 
exist not only in all the Crucifere, but in all parts of these vegetables, varying only in inten- 
sity. To this active, but very volatile principle, of whatever nature it be, they owe their medi- 
cinal virtues, which are stimulant and antiscorbutic, but which, requires, them to be used fresh, 
Our cabbages, turnips, radishes, knolkoles, &e. which belong to this family, are all too well 
known to require notice here; they owe their fitness for food to their acrid properties being 
diluted by an abundance of mucilage. Several species, such as the rape and mustard, are culti- 
vated in Europe on account of the oil which their seeds contain, but could never be profitably 
figure was made from a native specimen. ‘T'wo species of the genus Cardamine are found truly 
native on both the Neilgherries and Pulney mountains, the Capseila (Sheepherd purse) is also 
found in abundance on the former of these ranges, but I suspect introduced with corn seed.
