I knew a gentleman who prided himself all his life on being a connoisseur of Lafitte.

Dunster removed the cigar from his teeth and gazed at the long white ash with the air of a connoisseur.

Pickup, employed in a lawyer's office, terrified us all by the information that a gentleman related to our venerable connoisseur had seen the Rembrandt, had pronounced it to be an impudent counterfeit, and had engaged on his own account to have the picture tested in a court of law, and to charge the seller and maker thereof with conspiring to obtain money under false pretenses.
