ILFRACOMB, a town of Devonshire, seated on the Severn sea, almost opposite to Swansea in Glamorganshire, 181 miles from London. It has a considerable trade, especially in herrings, which are caught in the Bristol-channel. It is noted for maintaining constant lights to direct the sailors; for its convenience of building and repairing ships; and for the safe shelter ships from Ireland find here, when it is extremely dangerous for them to run into the mouth of the Taw. It had a quay or pier 350 feet long; but by time and the violence of the sea all went to decay; to remedy which, the parliament passed an act in 1731, and in 1765 it was partly rebuilt, lengthened and enlarged. It is governed by a mayor, bailiffs, &c., and consists chiefly of one street of scattered houses almost a mile long. The number of inhabitants in 1811 is stated at 1934. W. Long. 3° 10' N. Lat. 51° 11'.

ILLIAC PASSION, a violent and dangerous kind of colic; called also volvulus, miserere mei, and chordaplexus. It takes its name from the intestine iliac, on account of its being usually affected in this distemper; or perhaps from the Greek verb ἰλίας, "to wind or twist;" whence also it is the Latins call it volvulus.
