It was thought that it would also be of interest to test cigars 
of commerce for oxidizing enzyms. 
Of the samples procured, which 
were probably of very different ages, not one contained oxidase or per- 
oxidase, but catalase was present in all, although the amount differed

As to cigarette tobacco, five different brands of 
cigarettes were examined, viz, Old Dominion, Sweet Caporal, Gold Leaf, 
Chesterfield, and Egyptian Prettiest, but only in the last named was 
any catalase fou
