The auricles often beat many times more frequently than the ventricles, even two or three times as frequently, and, of course, these auricular contractions are not transmitted to the arterial system, and the radial pulse notes only the contractions of the ventricles. The phrase that is used to describe this nontransmission of the auricular stimulus to the ventricles is "heart block."
Before determining that the heart is slow, it must of course be carefully examined to determine if there are beats which are not transmitted to the wrist; also whether a slow radial rate is not due to intermitence or a heart block. While any pulse rate below 50 should be considered abnormal and more or less pathologic, still a pulse rate no lower than 60 may, be very abnormal for the individual.
Kennedy passed over the doubtful evidence of strangulation for the more profitable examination of the little gash in the wrist. "The radial artery has been cut," he mused. A low exclamation from him brought us all bending over him as he stooped and examined the cold form. He was holding in the palm of his hand a little piece of something that shone like silver.
On flexing the wrist, the hand is tilted to the radial side, but the paralysis of the flexor carpi ulnaris is often compensated for by the action of the palmaris longus. The little and ring fingers can be flexed to a slight degree by the slips of the flexor sublimis attached to them and supplied by the median nerve; flexion of the terminal phalanx of the little finger is almost impossible.
Stem simple till it becomes old, when it develops offsets at the base, broadly cylindrical, 8 in. high, 5 in. in diameter. Tubercles four-sided at base, prism-shaped, bearing pads of white wool in the corners at the base, and crowned with tufts of from four to seven spines, usually all radial, sometimes one central.
But the results of spectroscopic measurements of radial velocity are independent of the distance of the star. But let us not claim too much. We cannot yet say with certainty that the stars which form the agglomerations of the Milky Way have, beyond doubt, the same average motion as the stars in other regions of the universe.
There were no signs of external injury about his thoracic cavity and no fracture of the ribs could be detected, although carefully searched for; there was marked emphysema; the neck and side of the face were enormously swollen with the extravasated air; the tissues of the left arm were greatly infiltrated with air, which enabled us to elicit the familiar crepitus of such infiltration when an attempt at the determination of the radial pulse was made.
In Figs. 11 and 12, which show a few tracheæ and medullary rays of the ligneous bands of the same plant, we observe the same phenomenon. We might cite a large number of analogous examples, but shall be content to give the following: Figs. 13 and 15 represent radial and tangential sections of the bark of Syringodendron pes-capræ.
The hard-skinned "five finger," or common starfish, which we may pick up on any beach, while it never grew upon a stem, yet still preserves the radial symmetry of its stalked ancestors. Pick up your starfish, carry it to the nearest field, and pluck a daisy close to the head. How interesting the comparison becomes, now that the knowledge of its meaning is plain.
Beautifully tooled, light stone lintels with fine-scale radial scorings greatly enhance the beauty of the fenestration. Each lintel appears to consist of seven gauged or keyed pieces each, but is in reality a single stone, the effect being secured by deep scorings.
