Discussion 187 



Zuckerman: Is it possible that you can get other effects in the end- 

 organ? Dr. Harrison Matthews has just cited the hummel, which never 

 grows any antlers at all. Experienced stalkers also believe that, if the 

 sensitive velvet is bruised in one season, and antler growth is deformed, 

 the animal will never grow points again in the corresponding part of his 

 antlers. I do not know whether Dr. Harrison Matthews can confirm 

 that? 



Matthews: Yes, that is so but is it a very close observation? The fact 

 is that the animal has a deformity in the same place every year, but it is 

 merely guesswork to say that it was caused in the first instance by 

 damaging. 



Zuckerman: That is certainly true. 



Matthews: Of course, there is another wonderful yarn that goes around 

 among deerstalkers and that is, if an animal gets accidentally uni- 

 laterally castrated the horn on the opposite side is always deformed or 

 even absent.
