Midline gages were placed in the posterior (P), middle-posterior (MP), middle (M) and/or anterior (A) sections of their respective sutures. Bone and coronal suture gages were placed on right (R) and/or left (L). Totals are given for total gage sites (number of subjects).

The interparietal sutures of pigs 155, 156 and 165 gave very low strains (less than 10 με) under all conditions. Examination of the dried skulls revealed synostosis in 155 and 165. Although the suture appeared patent in 156 (a sibling of 155), we assume that some internal fusion had occurred and was the cause of the low strains. Data from these gages were not used in the calculations.
