1(»1<1 1110 iliat during llie lifetime of his fallier tlipy liad at several (lilVeiriit 

 limes tried to raii-e slieep Imt they would all die in the course ol" a few 

 years. T foinid Ihree calves visilily diseased. The most serious one 

 presented ilic fnllowinji- symptoms: (';ilf somewhat emaciated, tem]>. 

 normal, resp. highly accelerated and through mouth; calf stood with 

 he^d slightly extended downward and forward; had severe dry cough, 

 visible mucosae somewhat anemic and bowels loose. I suspected lung 

 wonn infestation but on aiit(»psy of this calf to my great sur[»rise not 

 a lung worm was found, but one of the most extensive cases of gen- 

 eralized vesicular emphysema T have seen, and a large number of 

 stomach woi-ms in the abomasum. An interesting question arises in 

 connection with this case: Has the em[)hyseiiiatons condition of the 

 lungs any relation to the parasitic infestation? Probably the most 

 common causes of cm])hysenia are increased ditliculty of expiration 

 (as would occur in chronic bronchitis) and diminished elasticity of the 

 alveolar wall. However, in human pathology many cases of emphysema 

 seem to follow cases of malnutrition.
