1872.] The Physiological Position of Tobacco. 481 
After smoking 11 minutes—112, 108, 107, IOI, I0I, 100, 
100, 100, 100, 98, and gr. 
There was thus a maximum increase of 373 pulsations 
per minute. 
Experiment 2. 
(Smoking through camphor julep in a hookah). 
Pulsation before smoking, 79$ per minute. 
Smoking 6 minutes—8r1, 81, 81, 83, 82, 82 per minute = 81°6 
average. 
Smoking 17 minutes—85, 89, 89, 93, 96, 90, 94, 94, 93, 92, 
95) 95. 95» 96; 94, 97, 93 = 93. 
1 
The maximum increase was 175 pulsations per minute. 
Experiment 3. 
(Smoking an empty pipe). 
Pulsation before smoking, 78 pulsations per minute. 
Smoking Tr minutes—76, 78, 77, 76, 79, 79, 80, 80, 79,78, 
and 79. 
There was no increase in the rate of pulsations from the 
effort of smoking, or from its interference with the re- 
spiration. 
Experiment 4. 
(To ascertain if, after smoking 6 minutes, during which the 
effect is very small, and then ceasing smoking, any 
increase in the effect would follow). 
Pulsation before smoking, 75 pulsations per minute. 
Smoking 6 minutes—76, 75, 79, 79, 76, 78. 
Smoking I minute—82. Cease smoking. 
Smoking ro minutes—81, 88, 83, 82, 84, 83; 83, 80, 82. 
The rate of pulsations was maintained, but was not ma- 
terially increased. 
Experiment 5. 
(To prove if the rapidity of smoking causes a variation in 
increase of pulsation). 
a. Greater volume of smoke.— 
Pulsation before smoking, 70} per minute. 
Smoking 6 minutes—68, 70, 71, 70, 72, 74 = 70°8 average. 
Smoking 6 minutes—76, 77, 86, 89, 91, 94 = 85°5 average. 
Smoking 4 minutes—98, 95, 96, 95 = 96’0 average. 
The maximum effect was thus 273 pulsations per minute.
