Small dose of Chloroform, causes rapid, even spasmodic movement; & but if very small dose, be given & the tentacles do not reach centre, they are paralysed & do not move with meat on gland under from 2 to 4 hours.

Nitric Ether, sometimes causes a few tentacles to move; & then all are paralysed for some hours.

Sulphuric Ether, caused no movement, & tentacles were paralysed for one or two hours

Alcohol caused no movement; & tentacles were paralysed for about one hour.

Carbonic Acid: plant exposed for one hour; caused no movement, but I think slightly dulled power of movement

Turpentine, vapour of for 15' caused no movement, & entirely stopped subsequent action of meat.—

All substances used in fluid state

Stramonium Tobacco Henbane Hemlock Strong infusion of Tea} produced no effect; caused no movement, & subsequently meat caused usual rapid movement: I think tea rather dulled power of movement.—

Prussic Acid diluted Belladonna Digitalis} caused the tentacles to move rapidly.

Strychnine acetate of} caused no movement, & entirely stopped the subsequent action of meat & killed the glands. When a tentacle with an atom of meat had commenced moving the strychnine arrested the movement.

Veratria acetate of} caused no movement; & stopped for many hours any movement from meat; but some tentacles after several hours regained power of movement

Morphia acetate of, & common Opium} caused no movement, & stopped for one or two hours subsequent action of meat, & then the movement was excessively slow

Hemlock} caused no movement & stopped for some few hours subsequent action of meat

Poison from adder's fang} caused rapid movement; & produced no subsequent injury; perhaps acted merely like saliva, which from having some nitrogen causes movement

Poison from

Poison from an Ant {caused no movement, but stopped subsequent action of meat: concentrated acetic acid acts in same manner.
