 health was good, his habits very regular, his diet ordinary and

While the writers who have done me the honour to notice my

 those from the galvanic experiments have, by some, been called 

 in question. I have carefully considered what has been brought 

 against them, without being able to perceive its force. I cannot 

 help ascribing it, in some degree, to the novelty of the subject, 

 and to the circumstances which originally induced me to trouble
