Abstract
IF, in the early morning, when the eyes are first opened, one looks at the white ceiling, branching lines are to be seen resembling blood-vessels. These figures only persist for about one second. It seems necessary for the eyes to be closed, and have a long rest, to show them clearly. In the daytime quite a long rest is necessary for them to be visible at all.
