INFALISTACIO, an ancient punishment of felons, by throwing them among the rocks and sands, customarily used in port-towns. It is the opinion of some writers, that infalstacus did imply some capital punishment, by exposing the malefactor upon the sands till the next tide carried him away; of which custom, it is said, there is an old tradition. However the penalty seems to take its name from the Norman falsse, or falesta, which signified not the sands, but the rocks and cliffs adjoining, or impending on the sea-shore. Commisit feloniam ob quam fuit suspensus, utlegatus, vel alio modo morti damnatus, &c. vel apud Dover infalstacus, apud Southampton submersus, &c.
