THE HORNED ADDER. 107 



tobacco jiiice with impunity. The Hottentots will often kill the Puff Adder by spitting in its 

 face the juice of chewed tobacco, or making it bite the end of a stick which has been rubbed in 

 the tobacco oil found in all pipes that have been long used without being cleaned. 



The Bushmen are in the habit of procuring from the teeth of tliis serpent the poison with 

 which they arm their tiny but most fearful arrows. In the capture of the Puff Adder they 

 display very gi-eat courage and address. Taking advantage of the reptile's sluggish habits, 

 they plant their bare feet upon its neck before it has quite made up its reptiUan mind to 

 action, and, holding it firmly down, cut off its head and extract the poison at their leisure. 

 In order to make it adhesive to the arrow point, it is mixed with the glutinous juice of the 

 amarylUs. 



There seems to be no certain remedies for the bite of the Puff Adder. Ammonia appears 

 to be the least inefficacious substance for that purpose, and the natives occasionally attempt 

 to heal the injury by splitting a living fowl across the breast, and applying the still 

 palpitating halves to the wound. There is a Idnd of seed called the "gentleman bean," 

 wliich is said to have a beneficial effect. If one of these beans be placed on the recently 

 inflicted wound, it adheres with great finnness, and is said to absorb the poison from the 

 system, and to f aU off as soon as this object is achieved. The Bushmen are in the habit of 

 swallowing the poison whenever they kill a Puff Adder and do not need its venomous store 

 for their arrows, hoping thereby to render themselves proof against its effects. AATien exam- 

 ined under the microscope, the poison resolves itself into minute crystalline spiculse, not 

 unlike those of Epsom salts, which must be kept perfectly dry or they will soon vanish from 

 the glass on which they are placed. 



The color of the Puff Adder is brov\Ti, chequered with dark browTi and white, and with 

 a reddish band between the eyes. The under parts are paler than the upper. 



Several other deadly seri:)ents of the same country are closely allied to the puff adder. 

 The first is the Das Adder, or River Jack {Clotho naslcorids) of the colonists, remarkable 

 for the long curved horn or spine upon the nose, formed by the peculiar development of the 

 scales over the nostiil. This curious structure is only found in the male. In color it is much 

 darker than the puff adder, being black, marbled with a paler hue, and decorated with 

 sundry lozenge-shaped spots along the back. 



The Berg Adder {Clotho dtropos) is another of these fearful reptiles. As its name 

 denotes, it is found more among the hills and stony ranges than on the plains, but is not 

 unfrequently found upon the flats, and will sometimes intrude into very awkward positions, 

 such as the floor of a hut, or even the bed upon which some wearied man is about to cast 

 himself. It is not quite so jioisonous as the puff adder, though its looks are quite as unpre- 

 possessing, and it never bites unless purposely irritated or trodden upon. 



It is an ugly, thick-bodied, slow-crawling creatui'e, with a suddenly tajiering tail and a 

 most e\al looking head. It is not a large reptile, its average length being about eighteen 

 inches. Its color is olive-gray, marbled on the sides, and decorated along the back with four 

 rows of dark squared spots. 



Yet one more species of this genus deserves a passing notice. This is the Horned Adder 

 {Clotho cornutd), sometimes, but erroneously, called the Cerastes, a term that is rightly applied 

 to another Serpent shortly to be described. It sometimes goes by the popular name of 

 HoRNSMAN. It derives its name of Horned Adder from the groups of little thread-like horns 

 that are seen on the head, one group appearing above each eye. In some works of Natural 

 History, it is called the Plumed Yiper, in allusion to these curious groups. It is not very 

 graceful in form, being decidedly short, squat, and puffy in shape, but is very prettily 

 marked, its body being richly marbled with chestnut, covered with a multitude of minute 

 dots, and variegated with four rows of dark spots along the back, two rows running on each 

 side of the vertebral line.
