imulating effect on the
brain is so brief that tobacco can not properly be termed a stimulant.
Its effect is narcotic or deadening. Those who fancy that their thoughts
flow more readily under the use of tobacco are in the same case with any
other habitue whose thoughts can not flow serenely except under his
accustomed indulgence. That a sound healthy man, who has never been
accustomed to the use of tobacco, can do better mental or physical work
with tobacco than without it has never been shown. Indeed, such
experiments as have been made on students and others show to the
contrary.[46]

The statistics presented by Prof. Fred. J. Pack are of interest in this
connection.

football team were grouped as follows:
