 and not entail any extra fatigue, we must conclude that the 

 part played by the stimulant may he quite innocent and 

 desirable. Several years ago a wise teacher suggested 

 that a whip is appropriate for the lazy, but not for the

In spite of Ilollingworth's impressive 1 findings, it would 

 be unsafe to conclude that all people can advantageously 

 use tea and coffee. Many exceptions are apparent. Even 

 among the members of Hollingworth's squad the larger 

 doses caused some feverish conditions, headache, and 

 sleeplessness. If such reactions were marked and long 

 continued, there can be no doubt that the favorable effect.- 

 of caffein would soon be exchanged for detrimental one<. 

 Only three or four of the subjects were non-users of 

 caffein before the experimental period. It is probable 

 that there are a good many abstainers from coffee who 

 have learned by disagreeable experience that they must 

 do witlfout it. 



While we may not condemn in a sweeping fashion the 

 taking of caffein, nor even the guarded indulgence in 

 alcohol, there is no room for two opinions regarding the 

 dangers of more active drugs. All use of morphin. cocain, 

 and their congeners is perilous. Temperance in their 

 employment is conceivable, but seems scarcely ever to be 

 realized. The tendency to increase the dosage is alnio-t 

 Si-resistible. There is hardly a -pectacle so tragic as that 

 of the drug victim, steadily deteriorating in character, until 

 his moral cowardice, dishone-ty. and lack of self-respect 

 are incredible to the member- of his family. Some one 

 has said that "the drunkard turns night into day and the 

 morphinist turn- day into night." The influence of cocain
