and taste.”"—Dr. Duncan. Prunes, the dried fruit of 
Prunus domestica, are considered a mild laxative. Quince 
seeds, from the Pyrus Cydonia (Cydonia vulgaris), are sup- 
posed to have the power, in small doses, of repressing vo- 
miting: they are very acid. The fruit of the Dog-rose 
(Rosa canina) is said to contain citric acid. The petals of 
the Damask-rose (R. centifolia) are used for distilling rose- 
water. Brayera anthelmintica is said to be almost specific 
against tenia; it is an Abyssinian plant, and is much used 
at Constantinople.

Potsonous Properties. — The Amygdalee contain a* 
considerable quantity of prussic acid in the leaves and i in the 
seeds, and some of them are dangerous on this account. 
The Cerasus capricida proves fatal to goats which feed upon 
its leaves ; the leaves of the Cherry-laurel (Prunus Lauro- — 
‘cerasus, or Cerasus Laurocerasus) afford prussic acid by 
oe distillation ; and this acid may also be detected in Peach 
_ blossoms and leaves, and in the bark of the Bird-Cherry 
_ (Prunus Padus or Cerasus Padus). Bitter Almonds are oe 
_ dangerous in any considerable quantity, and their essential 
- ieee poisonous. Ee:
