wine as two or more glasses of port a day at my age (72) is that it
produces no perceptible or measurable effect when taken for, say,
three weeks or a month at a time, when compared with the like period
of total abstinence. 4. It may be said in favour of temperance or even
of extreme abstinence, that some of those men who have done most work
in their day--John Howard, Wesley, and Cobbett, for example--have been
either very moderate, or decidedly abstemious. But on the other hand,
such men as Samuel Johnson, who was a free liver and glutton, and
Thackeray, who drank to excess, have also got through a great amount
of work.

PROFESSOR ERNST HAECKEL,
JENA.


I find strong coffee very useful in mental work. Of alcohol, I take
very little, because I find it of no value as a stimulant. I have
never smoked.
