This cord is connected with groups of ganglia and nerve fibres in the abdominal region, and this in turn is connected with terminal ganglia in distant tissues. This system of nerves is distributed to the vital organs of the body. Bilateral facial paralysis. It may be either active or passive. The cause of anaemia of the brain is an insufficient blood supply.
The fastigiate trees and shrubs are a counterpart of the weeping forms. Here the tendency to grow in a horizontal direction is lacking, and with it the bilateral and symmetric structure of the branches has disappeared.
A well- composed picture calls up in the spectator just such a balanced relation of impulses of attention and incipient movements as suits an organism which is also balanced bilateral in its own impulses to movement, and at the same time stable; and it is the correspondence of the suggested impulses with the natural movement that makes the composition good.
The lowest class of Mollusks has been named Acephala, to signify the absence of any distinct head; for though their whole organization is based upon the principle of bilateral symmetry, it is nevertheless very difficult to determine which is the right side and which the left in these animals, because there is so little prominence in the two ends of the body that the anterior and posterior extremities are hardly to be distinguished.
The power of grasping was partly developed from and partly added to the old locomotor function of the fore limbs; the jerky aimless automatisms, as well as the slow rhythmic flexion and extension of the fingers and hand, movements which are perhaps survivals of arboreal or of even earlier aquatic life, are cooerdinated; and the bilateral and simultaneous rhythmic movements of the heavier muscles are supplemented by the more finely adjusted and specialized activities which as the end of the growth period is approached are determined less by heredity and more by environment.
In a bilateral involvement of this kind, weight may be frequently shifted from one foot to the other, or in chronic cases, where no marked pain is experienced, the subject stands squarely upon both front feet and no peculiar shifting of weight or pointing is evident. In some cases of hip or shoulder involvement, complete relaxation of all parts of the affected member may be noticed.
Such are possibly nevoid in formation. The ordinary anomalies of the palate are the fissures, unilateral, bilateral, median, etc.: they are generally associated with hare-lip. The median fissure commencing between the middle incisors is quite rare. Many curious forms of obturator or artificial palate are employed to remedy congenital defects.
Such symbolism will harmonize with the peculiar reproduction, before mentioned, of heads in the body of certain annelids, with the facts of serial homology, as well as those of bilateral and vertical symmetry.
Thus we may regard the elements as both attracting attention to a certain spot and dispersing it over a field. The ideal composition seems to combine the dynamic and static elements, to animate, in short, the whole field of view, but in a generally bilateral fashion. The elements, in substitutional symmetry, are then simply means of introducing variety and action.
The autopsy showed little save chronic myocarditis with brown atrophy, calcification of part of thyroid, non-united fracture of neck of left femur, moderate coronary arteriosclerosis. "Acute mania." Death from bilateral phthisis with numerous cavities and bilateral pleuritis.
