Many rulers have 12

Usage examples of inches.

If we suppose the glassplate to stand at a distance of seven inches from the end of the shoot bearing the filament, the dots when joined, will give nearly the same figure as if a filament seven inches long, dipped in ink, had been fixed to the moving shoot, and had inscribed its own course on the plate.

The first seedling observed was nearly two inches in height and had been etiolated by having been grown in darkness.

With a seedling 2 inches in height it was obvious, even without the aid of any tracing, that the uppermost part of the stem bent successively to all points of the compass, like the stem of a twining plant.

It would therefore be very liable to be devoured by animals, were it not protected by being buried whilst young and tender, at a depth of some inches beneath the surface.

After a long period without any rain, the earth had become lightcoloured and very dry, but it was darkcoloured and damp, even in parts quite wet, for a distance of at least six inches all round each flowerstem.

The cotyledons of another seedling of the same age, 5 inches in height, with 4 welldeveloped leaves, behaved at night in exactly the same manner.

These massive radicles, one of which was above 2 inches in length and .

Some of the radicles which were experimented on were young and short, most of them of moderate length, and two or three exceeded three inches in length.

A more vigorous young plant, bearing only 4 leaves, was then selected, and a filament was affixed to the midrib of the third leaf from the base, which, with the petiole, was 5 inches in length.

Apex of leaf 12 inches from the vertical glass, so figure considerably magnified.

The petioles rise direct from the ground, and are from 5 to 7 inches in length.

Apex of leaf 11 inches from the vertical glass, so movement considerably magnified.

The movements of a young leaf, nearly one inch in length, on the summit of a seedling plant only 3 inches high, were traced from the early morning of June 2nd to the evening of the 7th.

The same little plant, when grown to a height of 5 inches, was again observed during four days.

Apex of leaf 12 inches beneath the horizontal glass, so figure considerably magnified.
