CHAPTER XXI.
_CERTAIN DENTAL EXPERIENCES .-- AN UNFORTUNATE OFFICIAL_.
Mr.Potts has suffered a good deal from the toothache, and one day he went around to the office of Dr.Slugg, the dentist, to have the offending tooth pulled.

The doctor has a very large practice; and in order to economize his strength, he invented a machine for pulling teeth.

He constructed a series of cranks and levers fixed to a movable stand and operating a pair of forceps by means of a leather belt, which was connected with the shafting of a machine-shop in the street back of the house.

The doctor experimented with it several times on nails firmly inserted in a board, and it worked splendidly.

The first patient he tried it on was Mr.Potts.When the forceps had been clasped upon Potts' tooth, Dr.Slugg geared the machine and opened the valve.
