* The cardamine pratensis (lady’s smock) made into strong tea, whether in the 
green or dry state, and to be the only drink, is said to be a sovereign remedy foy 
convulsions in children. 
fin many of the species of cleome , there are more than six stamina, and not 
always unequal as to length ; that the only reason for introducing this genus to this 
v class, is the ngfjgnferpus,. glands being three, placed at each division of the calyx, 
except one; yet are often so very small, as scarcely tp be discovered by glasses. 
*The seed of th zsinapis arvensis (charlock or ketlock), according to Mr. Miller* 
is commonly sold under the title of Durham mustard . The common mustard is 
from the sinapis nigra , and grows four or five feet in hight. 
§ Sisymbrium nasturtium (water cress) is much admired as a sailed at Spring, 
arid is said to be preferable to all others against the scurvy; but as some people 
have suffered’by mistaking the creeping vjater parsnip for the true water cress, it 
may not be improper to give a short description of both.—The sisymbrium nas¬ 
turtium is of the class and order tetradynamia siliquosa , hath the pod declining, 
leaves feathered, leaflets somewhat hearted ; the small leaves have few indentures 
on the edges, are of a dark green, with a tincture of brown upon them, and the 
odd one at the end very large and roundish.—The sium nodijlorum (creeping water 
parsnip) is of the class and order pentandria digynia , hath the leaves feathered, 
umbels axillary sessile, the small leaves oblong, pointed, serrated on the edges, and 
are of a light green.
