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, burf-boulder, now boy-folder, third-borrow, tything-man, chief-pledge, and borrow elder, according to the diversity of speech in different places. This office is now usually called a bigg-constable. The head-borrow was the chief of ten pledges; the other nine were called band-borrows, or plegi manusae, &c.

Head-Mould-shot, a disease in children, wherein the futures of the skull, generally the coronal, ride; that is, have their edges shot over one 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 divulsion of the futures.

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