170 ANIMAL PARASITES. 



expensivencss, which also shares all the disadvantages of Kousso, 

 especially that of expelling the worm in fragments, and which, 

 lastly, from its extraordinary slowness of action, from the neces- 

 sity of a tedious preliminary treatment, produces sickness, vomiting, 

 &c, as well as other remedies — if any one will nevertheless 

 employ it, then, according to Dr. Behrens, the following rules 

 are to be observed : 



1. Preliminary treatment. — For three or four days before the 

 cure, nothing but easily digestible food is to be taken ; all sorts 

 of flour gruel and cakes are to be avoided, as well as potatoes, 

 and all spirituous liquors ; because in dogs to which the latter 

 were administered, the Panna produced no result (!). For 

 habitual costiveness, Carlsbad salts or lavements are to be 

 administered. 



2. Day of cure. — In the morning, fasting, every quarter of an 

 hour, 20 — 30 grains of Panna powder in as little water as pos- 

 sible, or in light beer, until 5J — 5iss have been consumed, 

 according to the age and condition of the individual. If the 

 bowels are not moved, castor oil is given some time after the 

 last dose. Too early an administration of castor oil tears the 

 worm away, according to Behrens, in consequence of the too 

 early occurrence of peristaltic movements; if it be administered 

 too late it is also injurious; it should be given when the worm 

 has arrived in the colon, which is easily to be ascertained, as the 

 patients (by hoaxing the surgeon,) may indicate how the worm 

 passes down. It is best given two hours after the last dose. 

 "When the bowels are violently moved, and too much of the medi- 

 cine has been given, the worm passes in fragments (which it cer- 

 tainly does even with doses of only 5J.) When the worm 

 hangs out, Panna clysters are administered (which are also of no 

 use, K.) 



Disagreeable circumstances soon disappear — -they are, vomiting, 

 especially in men, which, however, may be suppressed by the 

 will, and is not injurious when it does not occur for an hour 

 after the taking of the remedy ; and congestion of the head for 

 about an hour and a half. Pregnancy is no counter-indication, 

 any more than lactation and menstruation. Hysteric patients 

 may take 2 — 3 grains daily for a considerable time, which stops 

 the passage of the segments for some weeks (but certainly will 

 not kill the worm.) 



Of course the remedy which furnishes such extraordinary
