To cut the Nails of the Toes in the Water
"It is possible to perform actions in the Water, which one cannot do on Land; I my self have often brought my Great Toe to my Lips in the Water, which I could never do on Land, not on my bed. You must hold your knife in your right hand (if you are right-handed) and take up your left Leg, and lay the Foot on the right Knee; there you make take if from the left hand, and with the right cut your Nails without any danger. Thus you may also pick your Toes; and if this way has no other use or advantage, yet the dexterity of the management may serve to recommend it."
