f Lactuca sativa. (garden lettuce) as observed by Dr. Carradorri, shews great 
sensitive irritability at certain periods of its growth, for when it is in flower or in 
seed, if it be gently touched with the finger, a blade of grass, or any pointed body, 
it will emit a milky liquor, in the form of very minute drops ; but this phenomenon 
is said to occur only in the small amplexicaul leaves of the branches, or the leaf¬ 
lets of the calyx.
