cumscribed groups of muscles, with unconsciousness, advancing 

 to other brain disorders, and finally exhaustion and death. 



(d) Peritoneal Invasion. With development of the fluke in 

 the peritoneum (omentum, mesentery, etc.) no special symptoms 

 were observed. The lesions were discovered post-mortepi. 



Prevention. In our case, with small areas only of a large con- 

 tinent invaded by the parasite, every means should be taken to 

 extirpate it, and thus prevent a general diffusion which could 

 only mean a public calamity. 



Menox animals arriving from infested countries should be de- 

 tained in quarantine and under a rigid scrutiny to detect any 

 cough with rusty or bloody expectoration containing the elliptical 

 fluke-eggs. Animals showing such invasion should be at once 

 sacrificed and their carcases burned or boiled. The human vic- 

 tim should be kept under strict sanitary supervision, by prefer- 

 ence on a salt marsh, and compelled to expectorate only into a 

 .sputum box to be burned. If cuspidors are used indoors, they 

 should be dry and filled with salt which can be roasted or, if need 

 be, deeply buried. Any escape of the sputum into the soil, or 

 into fresh water, is only an invitation to the extension of the Para- 

 gonimus. 



Cats, dogs or hogs coughing up a rusty or bloody sputum, 

 should have the latter examined for the fluke eggs, and if found, 

 the host of the parasite and all of the same genera that have lived 

 with it, together with all susceptible animals in the same place, 

 or on the water shed from it, should be secluded and destroyed at 

 public expense, and the carcases safely disposed of as indicated 

 above. 



In case of hogs being found to be infested when killed, their 

 lungs, and viscera, together with those of all others coming from 

 the same source, should be rendered or otherwise thoroughly de- 

 vitalized. While it is perfectly true that the ova found in such 

 specimens cannot directly infest the persons who may eat them, 

 but must ( according to all analogy in trematodes), pass through 

 an intermediate invertebrate ho.st to fit them to infest the mam- 

 mal, yet if infested products are allowed to pass into consumption 

 at all, uncooked scraps are thrown out, the ova develop the 

 embryo, the latter finds its suitable invertebrate host, and the 

 propagation of the parasite and the di.sease follows. It is such
