[Footnote: _Are mighty monuments_, l. 450. The reader is referred to a few pages on this subject in Phytologia, Sect. XIX. 7. 1, where the felicity of organic life is considered more at large; but it is probable that the most certain way to estimate the happiness and misery of organic beings; as it depends on the actions of the organs of sense, which constitute ideas; or of the muscular fibres which perform locomotion; would be to consider those actions, as they are produced or excited by the four sensorial powers of irritation, sensation, volition, and association. A small volume on this subject by some ingenious writer, might not only amuse, as an object of curiosity; but by showing the world the immediate sources of their pains and pleasures might teach the means to avoid the one, and to procure the other, and thus contribute both ways to increase the sum total of organic happiness.] [Footnote: _How Life increasing_, l. 453. Not only the vast calcareous provinces, which form so great a part of the terraqueous globe, and also whatever rests upon them, as clay, marl, sand, and coal, were formed from the fluid elements of heat, oxygen, azote, and hydrogen along with carbon, phosphorus, and perhaps a few other substances, which the science of chemistry has not yet decomposed; and gave the pleasure of life to the animals and vegetables, which formed them; and thus constitute monuments of the past happiness of those organized beings. But as those remains of former life are not again totally decomposed, or converted into their original elements, they supply more copious food to the succession of new animal or vegetable beings on their surface; which consists of materials convertible into nutriment with less labour or activity of the digestive powers; and hence the quantity or number of organized bodies, and their improvement in size, as well as their happiness, has been continually increasing, along with the solid parts of the globe; and will probably continue to increase, till the whole terraqueous sphere, and all that inhabit it shall dissolve by a general conflagration, and be again reduced to their elements. Thus all the suns, and the planets, which circle round them, may again sink into one central chaos; and may again by explosions produce a new world; which in process of time may resemble the present one, and at length again undergo the same catastrophe! these great events may be the result of the immutable laws impressed on matter by the Great Cause of Causes, Parent of Parents, Ens Entium!]
