Mounfey, with a farther account of the cafe of this 
fame Mr. Butler. 
Dr. Mounfey ’s Letter to Mr. Baker. 
Dumfries, Mar. 4th, 1763.

does not much attend to theory and conje&ure; fo I 
jfhall omit to give my opinion of caufes and their way 
of operating, and only fend a fimple narration of 
fads, in the fame order they happened, extracted 
from my notes taken upon this occasion.

handling of fome kinds of metallic inodorous bodies 
gave him anxiety, tremor, faintings, and many other 
uneafy fymptoms.

threw him into thefe diforders j and he affured me, 
that the handling copper or iron had the fame effed 
on
