The puff-adder (vipera inflata) was not uncommon in Namaqua-land and Damara-land. My saddle-ox had an exceedingly narrow escape from being bitten by one. The reptile was lying at length across the path, and I did not discover it until the ox almost trod on it. Any serpent less slow in its movements must have fixed its fangs in the animal.

The common people at the Cape have some very singular notions and superstitions about the different reptiles indigenous to the Cape Colony, but more especially with regard to
