_Middle lacerated foramina. Posterior lacerated foramina._—As repeatedly pointed out by the writer on former occasions, the middle lacerated foramina are structures of some importance. They are very small in the anthropoid apes, generally small in negro skulls, submedium to medium in the yellow-brown races and in less developed whites, and reach their maximum spaciousness in civilized modern white men. These differences are connected with the increase in the size of the brain. A growing brain not accompanied with a proportionate or equally rapid increase in the bony structures of the base of the skull (which seems to be most frequently the case) will cause a spreading and bulging of the basal parts, one result of which will be the increased size of the middle lacerated foramina. In the Munsee, in only two of the nineteen skulls in which the basal region is sufficiently well preserved for examination, the foramina about equal in size the average in whites; in nearly half of the remaining skulls they are submedium, and in slightly more than half they are small.
