Page 35 - A provision, of a very simple kind, is, in some cases, made to prevent the male and female blossoms of the same plant from breeding together, this being found to hurt the breed of vegetables, just as breeding in and in does the breed of animals. It is contrived, that the dust shall be shed by the male blossom before the female is ready to be affected by it, so that the impregnation must be performed by the dust of some other plant, and in this way the breed be crossed.
Page 1 - Providence, every part would be found in harmony with a plan of absolute benevolence. Independently, however, of this most consoling inference, the delight is inexpressible of being able to follow, as it were, with our eyes, the marvellous works of the Great Architect of Nature — to trace the unbounded power and exquisite skill which are exhibited in the most minute, as well as the mightiest parts of his system.
Page 43 - ... circumstances puts him out. Be the method ever so general, cases will always arise in which it must be varied, in order to apply; and if the workman only knows the rule without knowing the reason, he must be at fault the moment he is required to make any new application of it.

Page 32 - This is the thing required to be gained in the third eyelid, and the contrivance is exactly that of a string and a loop, moved each by a muscle, as the two strings are by the hands in the cases we have been supposing.
Page 47 - But if the knowledge of the doctrines unfolded by science is pleasing, so is the being able to trace the steps by which those doctrines are investigated, and their truth demonstrated: indeed, you cannot be said, in any sense of the word, to have learnt them, or to know them, if you have not so studied them as to perceive how they are proved. Without this you never can expect to remember them long, or to understand them accurately; and that would of itself be reason enough for examining closely the...
Page 46 - ... it grows in by night, and of an animal on the same air at any time, nay, and of a body burning in that air ; and yet all these are the same operation. It is an undeniable fact, that the very same thing which makes the fire burn, makes metals rust, forms acids, and...
Page 44 - The new process of Refining sugar, by which more money has been made in a shorter time, and with less risk and trouble, than was ever perhaps gained from an invention, was discovered by a most accomplished chemist,* and was the fruit of a long course of experiments, in the progress of which, known philosophical principles were constantly applied, and one or two new principles ascertained.
Page 34 - ... between the foot and the glass or wall. The consequence of this is, that the air presses the foot on the wall with a very considerable force compared to the weight of the fly ; for if its feet are to its body in the same...
Page 1 - Without perceiving the most extraordinary traces of design; and the skill, every where conspicuous, is calculated in so vast a proportion of instances, to promote the happiness of living creatures, and especially of ourselves, that we can feel no hesitation in concluding, that if we knew the whole scheme of Providence, every part would appear to be in harmony with a plan of absolute benevolence.
Page 47 - Without this you never can expect to remember them long, or to understand them accurately ; and that would of itself be reason enough for examining closely the grounds they rest on.
