 so portable in its form, but is more durable in its construction. 

 In fact, it produces the features of the ordinary stable muzzle 

 which we have already mentioned. 



The apparatus of CarHsle is also one of EngUsh invention, for 

 which great merit is claimed. We have used it, and the trial has 

 shown it to possess many features of marked superiority over the 



others.
