parasite can be seen. In the mucus from the smaller tubes 

 a few of the adult worms occur, and on spreading it out on 

 glass slips, and examining with a low power, a few ova and 

 free embryos are seen. 



" Blood of heart and veins contains no parasites. 

 " Nothing abnormal in the stomach or intestines ; a 

 large specimen of taenia elliptica in the latter, also a few as- 

 carides. 



" Case 6. — A thin, badly nourished dog pup, six months 

 ■old. Lungs present numerous patches of consolidation, in- 

 volving on the right side the lower half of the anterior lobe 

 and a large piece of the posterior lobe. On the left side 

 the free borders of the anterior and middle lobes for almost 

 two inches from the margin, and a broad strip along the 

 upper part of the posterior lobe. 



" Trachea and bronchi healthy ; mucous membrane of 

 the tubes in the affected parts congested, but no parasites 

 in the membrane or in the lung-tissue. 



" Stomach and intestines appear natural ; a few ascarides 

 in the latter. Nothing abnormal found in the blood. 



" Case 7. — Dog pup, seven months old. The autopsy, 

 which was made at the same time as the previous case, re-

 sence of any parasites either in the tubes or in the paren- 

 chyma of the lungs. Nothing ' unusual in the abdominal 

 organs. The taenia elliptica and five or six ascarides in the 

 iejunum. 



" Case 8. — A fine, well-grown dog pup, eight months 

 ■old. Had been ill a week. 



"Lungs contain pneumonic areas of considerable extent; 

 in the right involving the entire apex with the dependent 

 border, and a small portion of the posterior lobe near the
