 or three days except with neuralgia ; no surgical 

 operations except inoculation, drawing of one 

 tooth, and cutting of corns." l

 late Sir Henry Holland, who was on my list : 

 "Certain it is, as all who have fallen in with 

 him by sea or land will attest, that he might

 a few days afterwards, he was killed by a fall down stairs 

 at Oxford!
