Observations have been made of the proton groups resulting from the deuteron bombardment of a carbon target enriched to 60% in ${\mathrm{C}}^{13}$. A total of twenty-four such groups was observed, of which eleven have been assigned to levels in ${\mathrm{C}}^{13}$ and thirteen to levels in ${\mathrm{C}}^{14}$. The experimental angular distributions are compared with the predictions of stripping theory. The excitation values for twelve previously unreported levels have been obtained with probable errors of ±0.02 Mev. These levels are at 7.47, 9.50, and 9.90 Mev in ${\mathrm{C}}^{13}$ and at 6.59, 7.35, 8.32, 9.80, 10.43, 10.50, 12.60, 12.85, and 12.96 Mev in ${\mathrm{C}}^{14}$.
