In a book published in the same year, William Berry noted the presence of an "iron hook of a gate hinge" on some rocks, approximately three miles out at sea from Lihou, along with the remains of old roads, and surmised that Lihou may have been significantly larger in the past but that the sea had eroded a considerable portion.
Nun libro publicado no mesmo ano, William Berry sinalou a presenza de ganchos de ferro das bisagras das portas nalgunhas rocas, aproximadamente a tres millas mar dentro desde Lihou, xunto cos restos de antigos camiños, polo que conxeturaron que Lihou podía ser significativamente maior superficie no pasado pero que o mar erosionara unha parte considerable.
