192 A COLLECTOR'S EXPERIENCES 



Growing behind tlie two fangs in use are otlier 

 fangs, and still tlie embryos of others. Every six or 

 eight weeks the fangs are shed. By a wonderful pro- 

 vision of Nature, the serpent never loses an old fang 

 until the new member is strongly attached at its side, 

 and connected with the poison-gland ; then the old 

 fang comes loose from its socket, and is left deeply 

 embedded in the body of the next animal struck for

 made by the small jDalatine teeth Avould form excellent 

 sources for the absorption of the poison. 



Although much has been said concerning the 

 aggressive disposition of the venomous snakes, the 

 writer, after many years of experience, has failed to 

 note a single instance of the deliberate intention on 

 the part of a poisonous serpent to pursue. or exhibit 

 aggressiveness toward an enemy. The defensive is

 and although a specimen will occasionally show the

 It merely forms an anchor, and aids the reptile in
