THREADWORMS. 105 



Norfolk, about fifty years of age, has been a great 

 sufferer from oxyurides. The irritation thus occa- 

 sioned has sometimes been so extreme that his 

 public duties have been carried on with great 

 difficulty. He had been recommended to take 

 steel, but found its employment detrimental to his 

 general health ; on the other hand, he has derived 

 great advantage from the use of the natural waters 

 of Homburg, and during his occasional visits at the 

 spa he appears to have been perfectly free from 

 any parasitic annoyances. The entozoa have, how- 

 ever, invariably reappeared shortly after his return 

 to England. Partly in imitation of the mineral 

 water treatment I advised the taking of saline 

 aperients, followed by the frequent employment of 

 enemata of strong infusions of quassia and tansy. 

 This treatment had the effect of bringing away 

 great nnmbers of parasites; but he never feels 

 himself to be entirely free of his enemies except 

 when actually residing at Homburg. 



CASE LXIII. M. H., a young lady twenty years 

 of age, residing in the northern suburbs of London, 

 is subject to repeated attacks of threadworm. They 

 have tormented her for some six years past, during 

 which time she has been constantly dyspeptic; 

 being also subject to frequent bleedings at the 

 mouth in the early morning. Most of her symptoms, 

 however, were those of chlorosis. The marked 

 anaemia and puny state of the skin, together with
