Cassia neglected neglecta June 8th (was awake at 6. 45' a.m)

Left Hand Cot 5° 1/2 above horizon at (8° ( 9' am) rubbed delicately on upper side with pointed stick for 1.'

(after 10' from commencement of rubbing 11° above horizon, so on risen only 5° 1/2

(after 19' from do 12° above horizon.)

(at 8° 48' had sunk again (ie after 39') & stood at only 8° 1/2 above horizon

[Rest of the data not transcribed]

But now at 4° 15 a cot which was hardly was not touched has gone to sleep ─ So the most the rubbing did was to accelerate going to sleep

June 9 Cots. by no means open at 6° 45 a.m. fully open at 7° 45' a.m

pollen brought from another plant at Chatsworth contained from respectively 60 and 75 seeds. I have given these statements because Prof. Caspary advances this plant as a case opposed to the doctrine of the necessity or advantage of cross-fertilisation: see Sitzungsberichte der Phys.—oko. Gesell. zu Konigsberg, B. VI. p. 20.)

Delphinium consolida (Ranunculaceae) produces many capsules, but these contain only about half

June 9th Cassia neglected (see before

8° 49. a.m rt hand Cot of fresh fresh plant 6° above, (line from apex to joint) rubbed for 1' with same stick but supporting Cot on nail of other hand.

After 10' (counting from commencement of rubbing) 28° above horizon ie. rose 18°

→ (opposite Cot equally affected)

at 2.52' P.m. 10° above horizon, rubbed in same manner for 1' (N.B this is about same time hour before sleep, as the morning rubbing was before fully awaking)

After 5' (from time of rubbing) 26° angle above horizon ie. rose 16° → (opposite Cot. equally affected)

After 10' angle 25°

(So it does not appear that Cot move more readily in evening about alm 1 1/2 before sleeping time, than shortly after waking in the morning.)

Papaver alpinum. (d0), H. Hoffmann (Speciesfrage 1875 p. 47) states that this species produced seeds capable of germination only on one occasion.

Corydalis cava (Fumariaceae), sterile: see my the previous discussion on self-sterile plants.

Corydalis C solida. (do), I had a single plant in my garden (1863), and I saw many hive-bees sucking the flowers, but not a single seed was produced. I was much surprised at

C. neglecta

3°. 55

(1) Pin Cot on this side Horizontal (a young & fresh seedling)

4° 31' rubbed with stick for 30" supporting lower surface

4. 37 decidedly a little risen

4 45 29° above Horizon, & opposite Cot. equally risen—

5° fallen to 39° above Horizon, but sleep now coming in as some of other Cots. beginning to rise—

This case proves that Cots not insensible & yet not acted on by 1/2° of sun not very bright— so I conclude burning with lens 1 Cot did cause both Cots to rise, as much as stated

(after 10' no effect) — sun not very bright

4° 30' no effect

the flowers which were visited by bees produced between five and six times as many seeds as those which were protected. The covered-up plants not having been much exhausted by seed-bearing, bore a second considerable crop of flower-stems, whilst the exposed plants did not do so.

Cytisus laburnum (do), Seven flower-racemes of flowers ready to expand were enclosed in a large not bag made of net and they did not seem in the least injured
