(St) HEAD, a promontory of land in the southern extremity of the firth of Forth, in Scotland, 10 miles north of Berwick, and nearly the fame di- stance ABUTALS, signify the buttions or boundings of land towards any point. Limits were anciently distinguished by artificial hillocks, which were called botemines; and hence buting. In a description of the site of land, the sides on the breadth are more properly adjacenter, and those terminating the length are abbutantes; which, in old surveys, were sometimes expressed by capitare, to head, whence abbutals are now called head lands.
