 hens. Barrow-hogs have also small tusks 

 like sows. 



Thus far it is plain that the deprivation 

 of 'masculine vigour puts a stop to the growth 

 of those parts or appendages that are 

 looked upon as its insignia. But the in- 

 genious Mr. Lisle, in his book on husbandry, 

 carries it much farther ; for he says that 

 the loss of those insignia alone has some- 

 times a strange effect on the ability itself: 

 he had a boar so fierce and venereous, that 

 to prevent mischief, orders were given for 

 his tusks to be broken off. No sooner had 

 the beast suffered this injury than his 

 powers forsook him, and he neglected 

 those females to whom before he was pas- 

 sionately attached, and from whom no 

 fences could restrain him.
