The point of interest is that in our previous experience we have found that the greatest number of pulmonary infarcts complicating cigarette smoking has occurred in dogs that have :.:noked a high nicotine cigarette. This occurred much less in the lightsmokers and also in smokers which~ a filtered cigarette was used. The other findings were minimal„ Pulmonary fibrosis and emphysema, slight, in the lungs as well as a passive congestion of a slight to moderate degree. ~t t OSCIIR •AUERaACH, ?t• D.
