THE VAAL RHEBOK 
to the diamond fields in September, 1871, shooting several vaal rheboks, 
the skins of whose backs were full of small holes, and embedded in the 
flesh under each hole was a large white maggot hatched from the egg 
deposited by a kind of bot-fly in the upper parts of their bodies, after a 
hole had first been drilled through the skin.
