adulterated. I have abstained from it for many years, indeed for
nearly a lifetime, with great advantage. In our climate none of these
stimulants are needed, and I very much question whether they are more
necessary elsewhere.

Accept my thanks for the questions you have addressed to me.

In reply to your enquiry, I beg to say that I have never smoked, and
that I take wine only at meals, and in moderation. I have never
observed any noticeable effect from wine so taken on mental work, but
should think it quite insignificant.

W. SPOTTISWOODE.
