Abstract: Lateral and anteroposteror aspect X-ray films were used to study the volume o f cranial cavity in 104 ( male 67, female 37) adults (ag ed 18_ 76). The measurments including cranial maximum length (X1 ) , cranial height ( X2 ) , cranial breadth (X3 ) , sagittal arc (X6 ) were found to be the significant factors in calculating the brain volume. The multiple correlative coefficient is R= 0. 74( female)— 0. 79( male). P 0. 0001. The stepwise regressive equation is then obtained as
1. male: Y^ = 1. 71X1+ 9. 67X3+ 2. 88X6- 1788. 02 (cm3 )
2. female: Y^ = 5. 38X1+ 5. 36X2+ 6. 14X3- 1541. 73 ( cm3 )
The equation may be applied to calculate the volume of cranial cavity o f the adult.
