I cannot conceive how the engages ever assimilated this animal with the buffaloe for there is not greater analogy than between the horse and the frog. this animal is found in greatest numbers in the sandy open parts of the plains, and appear in great abundance after a shower of rain; they are sometimes found basking in the sunshine but conceal themselves in little holes in the earth much the greater preportion of their time. they are numerous about the falls of the Missouri and in the plains through which we past lately above the Wallahwallahs. The Choke Cherry has been in blume since the 20th inst. it is a simple branching ascending stem. the cortex smooth and of a dark brown with a redish cast. the leaf is scattered petiolate oval accute at its apex finely serrate smooth and of an ordinary green. from 11/2 to 3 inches in length and 13/4 to 2 in width. the peduncles are common, cilindric, and from 4 to 5 inches in length and are inserted promiscuously on the twigs of the preceeding years growth. on the lower portion of the common peduncle are frequently from 3 to 4 small leaves being the same in form as those last discribed. other peduncles 1/4 of an inch in length are thickly scattered and inserted on all sides of the common peduncle at wright angles with it each elivating a single flower, which has five obtuse short patent white petals with short claws inserted on the upper edge of the calyx. the calyx is a perianth including both stamens and germ, one leafed fine cleft entire simiglobular, infrior, deciduous. the stamens are upwards of twenty and are seated on the margin of the flower cup or what I have called the perianth. the filaments are unequal in length subulate inflected and superior membranous. the anthers are equal in number with the filaments, they are very short oblong & flat, naked and situated at the extremity of the filaments, is of a yelow colour as is also the pollen. one pistillum. the germen is ovate, smooth, superior, sessile, very small; the Style is very short, simple, erect, on the top of the germen, deciduous. the stigma is simple, flat very short.
Any finer training or the use of the hands will develop the centre for the fore limbs, and, on the principles, may react on the more important region of the cortex. Hence in turning the fore foot into a hand, for climbing and grasping purposes, the primitive Primate entered upon the path of brain-development.
These changes are well brought out in skiagrams; instead of the well-defined narrow line which represents the epiphysial cartilage, there is an ill-defined, blurred zone of considerable depth. In the shafts of the long bones, owing to the excessive absorption of bone, the cortex becomes porous, the spongy bone is rarefied, and the bones readily bend or break under mechanical influences.
In dogs, the brain has been exposed, and the cortex of that organ has been observed to become anæmic during sleep. It is a matter of ordinary observation that in infants, during sleep, the volume of the brain becomes less, since the fontanelle is found to sink in.
There may be no normal fatigue, there may be no fatigue sensation, there may be no rest feeling on account of perceptions, or on account of associations, or on account of impulses to action; there may be no normal response in the subcortical center, there may be no physical effect in the cortex on account of an existing hyperæmia or on account of an abnormal condition of the cells.
In 1524 Cortex sent an officer "to reduce the people of Chiapas, who had revolted, which that commander effectually performed, for, when they could resist no longer, these desperate wretches cast themselves with their wives and children headlong from precipices, so that not above two thousand of them remained, whose offspring inhabit that province at this time."
The pituitary and the adrenal cortex are mutually assistant, alike in their influence upon the tone of the brain and sex cells. So there are combinations of glands to assist or restrain others, or to control a body function, or to determine the domination or abeyance of an instinct.
We also know that a certain rather small strip of the upper brain-surface, or cortex, about the size of two fingers, running upward and backward from just above the ear, controls the movements of the different parts of the body. One little patch of it for the hand, another for the wrist, another for the arm, another for the shoulder, another for the foot, and so on.
Thus, the walnut was regarded as clearly good for mental cases from its bearing the signature of the whole head; the outward green cortex answering to the pericranium, the harder shell within representing the skull, and the kernel in its figure resembling the cover of the brain.
If the process involving the adrenal cortex attacks it after birth, the symmetrical correspondence and harmony of the primary sex organs and the secondary sex characters are not affected. But there follows a curious hastening of the ripening of body and mind summed up in the word puberty, a precocious puberty, with the most startling effects.
