It was recently shown that in the photodisintegration of ${\mathrm{B}}^{11}$ certain expected $\gamma$ rays were missing. A partial explanation is offered here for the failure to observe these transitions. It is also pointed out that no conclusions about the strength of the $T=\frac{3}{2}$ giant resonance can be drawn from this experiment.
