Page 5 - For the invisible things of God from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead...
Page 109 - The above and similar facts constituted all the knowledge of the ancients on the subject of fertilization ; and it was not till the latter part of the seventeenth century that any thing like proper notions began to prevail.
Page 112 - In Euphorbia Lathyris the apex of the nucleus is protruded far beyond the foramen, so as to lie within a kind of hood-like expansion of the placenta : in all...
Page 128 - This plant has ternate leaves : the terminal leaflet, which is larger than those at the side, does not move, except to sleep ; but the lateral ones, especially in warm weather, are in continual motion, both day and night, even when the terminal leaflet is asleep. External stimuli produce no effect; the motions are very irregular ; the leaflets rise or fall more or less quickly, and retain their position for uncertain periods. Cold water poured upon it stops the motion, but it is immediately renewed...
Page 129 - But who can paint Like Nature? Can imagination boast, Amid its gay creation, hues like hers ? Or can it mix them with that matchless skill, And lose them in each other, as appears In every bud that blows...
Page 141 - ... of amylaceous matter, which, in some cases, is converted into sugar, no doubt, in consequence of the action of some acid, formed by the decomposition of the organic parts. 3. That the action of frost operates separately upon each individual elementary organ, so that a frozen plant contains as many icicles as there are cavities containing fluid ; the dilitation thus produced not being sufficient to burst the sides of the cavities.
Page 141 - Goeppert, he denies the truth of the statement generally made, that frost produces death in plants by bursting their vessels; and he assigns the effect to other causes. His more important conclusions are — 1.

Page 143 - Schultz supposes, this is the vital fluid of plants, such a fact would alone account for the fatal effects of a low temperature. In all the cases I have observed frost coagulates this fluid, collecting it into amorphous masses.
Page 45 - It does not, however, appear that this inquiry has led to any thing beyond the establishment of the fact, that, beginning from the cotyledons, the whole of the appendages of the axis of plants — leaves, calyx, corolla, stamens, and carpels — form an uninterrupted spire, governed by laws which are nearly constant.
Page 143 - It is well known, that the same plant growing in a dry climate, or in a dry soil, or in a situation thoroughly drained from water during winter, will resist much more cold, than if cultivated in a damp climate, or in wet soil, or in a place affected by water in winter. Whatever tends to render tissue moist will increase its power of conducting heat, and consequently augment the susceptibility of plants to the influence of frost; and whatever tends to diminish their humidity, will also diminish their...
