Drosera

June 20 8˚ A.m.

4 Leaves very fine Hot-House with bits of rawish meat & saliva on Backs. — (21' 7˚ 30' not one of these have acted in the least.)

July 4th. Put drops of sugar & bit of meat on back of 5 or 6 leaves & kept damp under bell glass, after 36˚ I think some reflexion of tentacles & certainly of whole lam. of leaf backwards i.e. in direction opposite to what occurs when meat or fly caught — After 48˚ leaves injured & glands drying on disc— evidently exosmose & injured.
