AS TO SOUNDNESS. 93 
happened that the gentleman who was selling the horse 
was an old.acquaintance of my friend, and persuaded 
him, in spite of my warning, to purchase the brute. 
When the horse arrived in Leeds I was requested to 
give him an alterative ball, which I did, containing two

employer’s friend Sir G. W.; but the latter was espe-

thought him just a little flat-sided,-but that I had nothin:
