We are sorting antiquarian books in our Westport, NY storefront this afternoon, and encountered this peculiar illustration in the book The Story of Exploration and Adventure in Africa Compiled from the Most Authoritative Sources, Philadelphia: Henry Altemus, 1896.
The accompanying text read: "The natives of [Kalai] have a curious way of saluting strangers. Instead of bowing, they throw themselves on their backs on the ground , rolling from side to side and slapping themselves on the thighs, while they utter the words, "Kina bomba! kina bomba!" In vain Livingston implored them to stop."
Presumably "Kina bomba" translates to "Dr. Livingston, I presume."
