Reynolds Tobacco Company Winston-Salem NC 20712 USA. 4th July, 1989 Dear Pat, Re: Chronic nicotine administration increases tyrosine hydroxylation capacity selectively in the rat hippocampus I am enclosing a copy of a short manuscript which I, Jeffrey Gray and our co-authors plan to submit to 'Neuroscience Letters'. I don't think there will be anything in it which Reynolds will find contr oversial; we have acknowledged their support in the usual way. It would be very helpful if we could have Reynold's usual speedy reply on this one too. With thanks in anticipation. Yours sincerely, M.H.
