  <dc:title>Letter from N Giarman to J H Gaddum</dc:title>
  <dc:description>Letter from Giarman thanking Gaddum for identifying Mitchell; discounts Gaddum's suggestion that the effects of atrophine are due to general stimulation of the brain; suggests instead that it is due to drug-induced release of ACh [acetylcholine]; mentions recent research showing that the increase in ACh is localised in the quadrigiminal bodies of the brain stem.</dc:description>
