p 3.    narrow lining of Protoplasm in unaggragated cell

   { a    do    in cell in which there was a sphere of Protoplasm.    (Index 73)

{ In crushed cells the pulpy & granular matter may be in part the moving layer.

p.4 Liquid with spheres quite colourless.

   Huxley, Hooker & B. S. much struck with phenomenon.

p. 5.    lay some egg. after 2O. 45' raw meat.—

―    Purple contents aggregate externally at first, giving appearance of lining of cell separating form walls; (but not true as above I saw flowing current after spheres formed. The bag travels glides slowly, & spheres besides the bag travelling more quickly.

p 6 Repeat aggreg. of short central tents & greenish bags & greenish atoms — no grains of chlorophyll

p. 8. Raw meat    25O in strong infusion of raw meat — much agg. splendid circulation    spheres within bags— & spheres within spheres— —tails

p. 9.    2 gr. of C. of A. for 26O. 30'    no inflection no inflection. splendid aggregation    Central Tentacles central tents . not inflected aggr. ( circulation not observed) do gr. to 2. oz. No inflection

―    1 gr t 1 oz spheres running up & down same side — reaching round each other — & at unequal distances.

p. 10    Short central Tentacles aggregation current increased by C. of Am. (?)

―    spheres increasing in size as they circulated — Layer too narrow to fuse all the masses.

p. 11.    formation of little spheres in very pale leaf    — current of Protoplasm — greenish matter in very pale leaves.   

(Index 1873)

p 12    appearance of walls contents of cells shrinking form walls

13    after 2O 30; form immersion— a spheres 2/3 diameter of cell    small spheres travelling quicker than sheaf of Protoplasm    after 4O 25' spheres nearly filling up cell.

p 14th    After 5O  6    cells colourless —no flowing protoplasm, yet spheres smaller yet travelling

   15 & 16    continued aggregation for 22O of spheres —fluid now absolutely colourless. —No protoplasmic current p.16 characteristic visible. — it is certain granules are all aggregated— purple spheres almost touch walls.

p. 16    Crushing & splitting of sphere — 2 colours 17 so — small spheres of same colour as envelope of large spheres.

18.    Crushing very old & very red leaf — contents quit homogeneous.    pulpy pale & dark purple & greenish matter — not diffused.

(19 description of laminae little else)

p. 19    Phosphate of Ammonium & Put bit clasped meat for 24O. mass, not spherical & currents

p. 20    Crushed & them in C. of Am.
