July 20th The globular head, unicellular, the glands on margin & on valve have a nucleus & a layer of protoplasm all round walls. This layer in all the spec those immersed in solutions of N. of amm & C. of ammonia & raw meat is shrunk & sometimes ruptured, & no movement can be seen.— Can this be due to water of foot-[illeg] having become foul? The glands of quite young & clean bladders are in this state (a). They certainly were not so when we began our examination. — I can now judge of the effect of no solution. The glands on sides of orifice turn towards opening — The glands with long footstalks, which rise from the valve, also point towards the orifice.

I left glands in this condition for 3 or 4h in sol. of 4 gr. to 1 oz of C. of ammonia & the aggregation did not in the least increase. Neither Frank nor self could ever see any movement in protoplasm in this state.

These globular headed hairs can hardly & called "glands".—

Yet the plants are flowering & growing & seem perfectly healthy.

Huxley looked at quadrifid spines, at the little oval or globular body in each, undergoing Brownian movement & never saw such a thing, more like similar bodies in Chara.— [illeg] only 1 in each spine, but sometimes 2 or 3. Generally at base, but sometime in middle or near apex of spine.

C. of Amm makes lining of protoplasm of quadrifid hairs to shrink. — little spheres in pedicels of long glands on Valves
