The parasite should be vigorously attacked by an anthel mintie administered after a smart purge has cleared out the contents of the intestines, and 8 or io hours after any food has been swallowed. Thymol has been the routine agent; grs. should be given in a cachet to the lasting patient, and this dose repeated twice at intervals of 2 hours each (90 grs. in all). Some authorities recommend one colossal dose of oo grs. As a precaution against the absorption of the drug it is advisable to avoid the administration of any oily or fatty substance, though a small dose of Castor Oil can salely be administered 6 or 8 hours afterwards in order to expel the killed parasite, but upon the whole 5 grs. Calomel will prove more efficacious. 11, within a week or two, ova are detected in the faeces, the doses must be repeated as before. Daniels recommends
the administration of 15 mins. Oil of Eucalyptus and zo mins. Chloroform dissolved in 5 drs. Castor Oil after fasting, the dose to be repeated in one hour. Beta-Naphthol is believed to be less toxic than thymol, and may be given in similar dosage. _Manson reports favourably of Filix Alas in combination with Ether. Recently better results than those following thymol have been obtained by Oil of Chenopodium in doses of 6 mins., repeated three times at intervals of 2 hours each, the last being followed in 2 hours by 5 drs. Castor Oil and # dr. Chloroform, and this followed again in hali an hour by a i oz. dose of plain Castor Oil as advo cated by Billings and Hickey.
The after-treatment will embrace the administration of Iron, alone, or in combination with Arsenic, to combat the profound so con stantly present.
