There are many breeds which transmit their characters more or less truly.

I will here interrupt my account of the movements of the leaves, and describe the phenomenon of aggregation, to which subject I have already alluded.

The revolving movement of a tendril is not stopped by the curving of its extremity after it has been touched.

I have kept alive all the most distinct breeds, which I could procure in England or from the Continent; and have prepared skeletons of all.

I wished, therefore, to ascertain whether heat alone would induce inflection, and what temperature was the most efficient.

As some naturalists may not be familiar with the chief breeds of the fowl, it will be advisable to give a condensed description of them.

Splinters of clean glass were scattered on a large number of leaves, and these became moderately inflected.

I shall not enter into so much detail on the variability of cultivated plants, as in the case of domesticated animals.

Having found that the salts of ammonia were so powerful, I was led to investigate the action of some other salts.

As in the last chapter, I will first give my experiments, and then a brief summary of the results with some concluding remarks.

I have briefly abstracted these opinions for the sake of showing those who have never attended to such subjects, how perplexed with doubt they are.

The backs of the leaves bear numerous minute papillae, which do not secrete, but have the power of absorption.

By this term I include all those sudden changes in structure or appearance which occasionally occur in full-grown plants in their flower-buds or leaf-buds.

Movement ensues if a gland is momentarily touched three or four times; but if touched only once or twice, though with considerable force and with a hard object,

If an insect is placed on the central glands, or has been naturally caught there, the apex of the leaf curls inwards.

This plant, commonly called Venus’ fly-trap, from the rapidity and force of its movements, is one of the most wonderful in the world.

The leaves arise from an almost woody axis; they are linear, much attenuated towards their tips, and several inches in length.

Pinguicula vulgaris.—This plant grows in moist places, generally on mountains.

The collar (called the peristome by Cohn) is evidently formed, like the valve, by an inward projection of the walls of the bladder.

The leaves are entire, instead of being much divided, as in the foregoing aquatic species.
