That the amount of pleasure we receive is in exact proportion to the appearance of vigor and sensibility in the plant, is easily proved by observing the effect of those which show the evidences of it in the least degree, as, for instance, any of the cacti not in flower. Their masses are heavy and simple, their growth slow, their various parts jointed on one to another, as if they were buckled or pinned together instead of growing out of each other, (note the singular imposition in many of them, the prickly pear for instance, of the fruit upon the body of the plant, so that it looks like a swelling or disease,) and often farther opposed by harsh truncation of line as in the cactus truncatophylla. All these circumstances so concur to deprive the plant of vital evidences, that we receive from it more sense of pain than of beauty; and yet even here, the sharpness of the angles, the symmetrical order and strength of the spines, the fresh and even color of the body, are looked for earnestly as signs of healthy condition, our pain is increased by their absence, and indefinitely increased if blotches, and other appearances of bruise and decay interfere with that little life which the plant seems to possess. The same singular characters belong in animals to the crustacea, as to the lobster, crab, scorpion, etc., and in great measure deprive them of the beauty which we find in higher orders, so that we are reduced to look for their beauty to single parts and joints, and not to the whole animal. Sec. 5. This sympathy is unselfish, and does not regard utility.
