These remains are undoubtedly extremely ancient. The skulls ex- 

 amined, about fifteen in number, form an interesting group, somewhat 

 intermediate in form between the true Celtic and the roimd types. 

 The skuU figured is that of a child about eight years of age. The 

 bones are thin and delicate, and many of the sutures are slightly 

 separated. As in the former case, the posterior portion of this skull 

 is nearly normal, but the frontal region is greatly distorted. The 

 right external angular process of the frontal, and the right orbit are 

 forced downwards and inwards, and the left upwards and outwards. 

 The whole frontal bone is twisted round to almost exactly the same 

 degree, only in this case to the right, and in the other to the left. 

 The twist commences in both from the same line of comparative 

 weakness in the cranial arch, a line nearly coincident with, but not 

 involving the integrity of, the coronal suture. As shown in the wood- 

 cut, the physiognomy of the change in form in these two skulls is 

 almost precisely the same.
