I’d call this a writing prompt. This item is from the summer 1867 issue of the Richmond Medical Journal. It’s quite sober in tone for something so sensational: quadruplets, identical (as there was only one placenta), and they were all boys. Five pounds each and healthy at birth.
I had a quick look but couldn’t find any mention of these quadruplets in any of the lists of multiple births online. It might never have come to the attention of the list-makers, I suppose. But it’s odd.
