234 TREATMENT OF 



to the mucous membrane of the intestines. Tliis 

 case also instructs us, that the same method will 

 certainly fail when the armed taenia, at full growth, 

 is strongly fixed to the membranes of the intestines;i 

 and consequently occasions more severe symptoms. 

 I have had occasion to prescribe for these tae- 

 niae, when the age of the armed taenia was differ- 

 ent from that just mentioned. 



This difl'crence has however required an oppo- 

 site mode of treatment ; if the instance is not rare, 

 it is certainly instructive. 



§ CL. Further, the root of the polypodium filix 

 mas, even before the method of Herrenschwand 

 was'known, and before the secret of J>^ouffer was 

 revealed, had been employed by different physi- 

 cians in cases of taeniae and other worms, as we 

 have already announced. (174) Re7iard,{i7&) m 

 these cases, used to prescribe, in the evening, an 

 enema of soap dissolved in water, and during the 

 five following days administered, fasting, a drachm 

 of the pulvis radicis iilicis maris, dissolved in some 

 purslain, and soon after a bolus, compounded of 

 submuriate of mercury, of jalap, rhubarb and honey ; 

 and for common drink a decoction of the male fern 

 root. Vogel affirms,(17«) that nothing is more ef- 

 fectual ia expelling taeniae than half a scruple of 

 this root, and three grains of gamboge, taken morn- 

 i„p- and evening, for several days : the same thing 

 Ub been observed by Alix,{i77) by Duncan,{i7S) 

 etc.
