P., Cadaveric, of the vocal bands, the position which they a ume in paralysis of the recurrent laryngeal nerve. The affected band is in the median position, and is perfectly motionle . P. of the Fetus, the relation of the presenting part to the cardinal points of Capuron. For the vertex, the face and the breech, there are each four positions: a right anterior, a right posterior, a left anterior and a left posterior. For each of the shoulders there is an anterior and posterior position. In order to shorten and memorize these positions, the initials of the chief words are made use of as follows: For vertex presentations the word occiput is indicated by the letter O., and preceded by the letter R. or L., for right or left, and followed by A. or P., according as the presenting part is anterior or posterior. We thus have the initials L. O. A., left-occipito anterior, to indicate that the presenting occiput is upon the anterior left side. In the same way are derived the terms, L. O. P., P. O. A., R. O. P. For facial presentations we have in the same way, L. F. A. (left fronto-anterior), L. F. P., R. F. A., R. F. P. For breech or sacral presentations, L. S. A., L. S. P., R. S. A., R. S. P., and for shoulder (dorsal) presentations, L.D. A., L. D. P., R. D. A., R. D. P. See Table of Fetal Positions, under Fetus. P., Primary (of the eyes), that position in which the eyes can move laterally and vertically without rotating the vertical axis. P., Roser (of the head), the head dependent over the end of a table. P., Secondary (of the eyes), that position in which the vertical meridian is rotated away from its vertical position. P., Shoe-and-Stocking, a position so named by Allis, in which the limb of one side is cro ed upon the other, as in putting on the shoe and stocking, with the external malleolus of one side upon the patella of the opposite side. Inability to do this is diagnostic of disease in the hip-joint on that side. P.-test, a test for the function of coordination. If a normal individual be placed in a strictly erect position, with the heels and toes of the two feet closely approximated, a certain amount of swaying of the body occurs, especially if the eyes be shut.
