Of the total number 44 per cent, are smokers and 56 per cent, are 

 non-smokers. Of 213 students examined by Dr. Meylan at Columbia 

 University 52 per cent, were smokers and 48 per cent, were non- 

 smokers. 



From the following tables it will be observed that the two classes 

 of men are of practically the same age and weight.

While the differences in age and in weight are very slight, it should 

 be noted that they both are in favor of the smoker. This point will be 

 considered later.

It will be observed that smokers of the same age as non-smokers and 

 3.3 pounds heavier have a lung capacity of 22.6 cubic inches (7.3 per 

 cent.) smaller. Inasmuch as the smokers are heavier than the non-
