Head-Borough, signifies the person who is the chief of the frank pledge, and had anciently the principal direction of those within his own pledge. He was also called burrow-head, burshoulder, now borow-holder, third-borow, tything-man, chief-pledge, and borow-elder, according to the diversity of speech in different places. This officer is now usually called a high constable. The head-borow was the chief of ten pledges: the other nine were called hand-borows, or pleggi manuaxes, &c.

Head-Mould-shot, a disease in children, wherein the sutures of the skull, generally the coronal, ride; that is, have their edges shot one over another; and are so close locked together, as to compress the internal parts, the meninges, or even the brain itself. The disease usually occasions convulsions, and is supposed to admit of no cure from medicine, unless room could be given by manual operation or a division of the sutures.

The head-mould-shot is the disorder opposite to the horse-shoe head.
