The fingerprint patterns and palmar creases of 100 Chinese medical students were studied. It has shown that, of the fingerprints the ulnar Ioops(49.1?1.58％)and whorls (46.8?1.58％) are more abundant, while the arches (2.7?0.51％)and the radial loops (1.4?0.37％) are less frequent. The radial loops are primarily showed in the index finger (12/14).The arches appear in equal number among the index and middle fingers.There is a significant sexual difference in the fingerprint patterns. The male whorls are more abundant than female(P0.5).

0.01). The equation of regression is: =12.13—0.011X_1—0.07X_2+0.09X_3+0.21X_4. (——length of the brain, X_1 and X_2——the areas of left and right angular gyri, X_3 and X_4——the areas of left and right supramarginal gyri) There are three to four temporal transverse gyri found in 80?4％ of all the. specimens, The thickness of cortex here is 2.2-3.3 mm. In sections it shows the characteristicts of the granular cortex.
