Sometimes an ellipsis appears to be four dots rather than three. This is because the ellipsis is either preceded or followed by a period. Since the braille period is not the same as the dots of an ellipsis, it must be determined which of the four dots is the period.
If the sentence is incomplete, i.e., does not contain a subject and a verb and express a complete thought, then the ellipsis is taking the place of missing words within the sentence—in which case the period immediately follows the ellipsis, just as it would a word. If a sentence is grammatically complete, the first dot represents the period and the ellipsis represents a following missing sentence or sentences. In this case a blank cell is left between the period and the following ellipsis. Example:
As you can see, I have followed your career. . . . As to my own . . . . Well, you know the story.
