When Bloom takes his seat in the funeral carriage, the narrative notes that "He passed an arm through the armstrap." Such things do not exist today, but the reader who is sufficiently focused to notice this small detail might suppose them to be similar to the loops that now keep standing passengers in subway cars and urban buses from being thrown about––and such was indeed the case. The fact that Bloom steadies himself in an as-yet unmoving carriage is probably worth noting.
