Abstract
WAKING under my mosquito net one morning during a visit to India, I was surprised to find that the wall of the net before my eyes appeared to consist, not of a single vertical sheet of netting, but of three or more sheets. On closer examination, I found that these seemed to be arranged like the successive slats of a Venetian blind, and supposed this to be a binocular illusion—a variant of that mentioned by Prof. H. H. Dixon1—the nth mesh seen by one eye combining successively with the (n–l)th, nth, (n+1)th.... mesh fixed by the other eye.
